TDK Corporation distributor & excess inventory

About TDK Corporation

TDK Corporation was founded in December 1935 in Tokyo, Japan as Tokyo Denki Kagaku Kogyo K.K. (Tokyo Electrochemical Company) to commercialize ferrite, the magnetic ceramic material invented in 1930 by Yogoro Kato and Takeshi Takei at the Tokyo Institute of Technology. Headquartered in Nihonbashi, Chuo, Tokyo, TDK employs roughly 100,000 people worldwide and runs one of the broadest passive-component, sensor, magnetics, power-supply, and battery portfolios in the industry — C-series MLCC and CGA automotive MLCC, EPCOS B-series aluminum electrolytic, film, PTC / NTC, EMC / EMI filter, and SAW / MEMS product lines, InvenSense MEMS motion and audio sensors, Micronas HAL Hall-effect sensors, Chirp Microsystems ultrasonic ToF sensors, Densei-Lambda industrial power supplies, ATL lithium-polymer cells for smartphones, and Headway Technologies HDD magnetic read / write heads.

What ships today as "TDK" is the result of an aggressive multi-decade acquisition strategy that customers still search for by legacy brand name. The EPCOS merger in 2008 — the Siemens / Matsushita passives spin-off — brought MLCC, film capacitors, aluminum electrolytics (B-series), PTC / NTC thermistors, EMC filters, SAW filters, and MEMS microphones into the TDK line card, and TDK-EPCOS remains a major sub-brand for European industrial and automotive customers. The InvenSense acquisition (2017) added MEMS gyroscopes, accelerometers, and IMUs — the ICM-20xxx and ICM-42xxx families plus legacy MPU-6050 / MPU-9250. Micronas (2016) brought the HAL Hall-effect sensor franchise (HAL 15xy / HAL 24xy / HAR direct-angle). Chirp Microsystems (2018) added the CH101 / CH201 ultrasonic time-of-flight sensor line. Tronics MEMS (TAS) brought industrial MEMS gyros. Densei-Lambda / TDK-Lambda (2008) added the HWS, RWS, DPP industrial power-supply lines. Amperex Technology Limited (ATL) (majority owned) supplies Li-polymer cells for smartphones. Headway Technologies supplies HDD magnetic heads. Faraday Battery supplies specialty cells. Each of these legacy franchises still ships product under its original brand on many long-lifecycle BOMs.

Hybrid Electronics has channeled excess and legacy TDK / EPCOS / TDK-Lambda / InvenSense / Micronas material since 1995. We support customers who need AEC-Q200 CGA automotive MLCC, CNA high-cap MLCC, and CEU wide-terminal MLCC in allocation, EPCOS B41xxx / B43xxx aluminum electrolytics and B32xxx DC-link film capacitors still specified on legacy inverter and drive BOMs, N87 / N95 / PC40 ferrite cores for SMPS transformer builds, InvenSense MPU-6050 / MPU-9250 legacy IMUs after their discontinuation, Micronas HAL 8xx legacy Hall sensors, TDK-Lambda HWS / RWS / DPP industrial PSUs including pre-acquisition Lambda-branded and Densei-Lambda-branded units, and older EPCOS-branded MLCC and thermistors that predate the TDK rebrand. Same-day quotes, factory-sealed reels where possible, and full traceability documentation on request.

Notable TDK part numbers we track

Hybrid Electronics quotes and sources the following TDK, TDK-EPCOS, TDK-Lambda, InvenSense, Micronas, and Chirp parts across MLCC, aluminum electrolytic, film, thermistor, ferrite, inductor, EMI-filter, SAW, MEMS, Hall, ultrasonic, PSU, and battery segments. TDK uses C, CGA, CEU, CNA prefixes for MLCC; EPCOS uses B4x, B3x, B5x, B6x, B8x for passives; TDK-Lambda uses HWS, RWS, DPP for PSUs; InvenSense uses ICM- / MPU- / ICS-; Micronas uses HAL; and Chirp uses CH. Contact us for the exact reel size, date code, temp grade, or AEC-Q200 tier you need.

Additional reels available across the full C-series / CGA / CEU / CNA MLCC library, the complete EPCOS B41 / B43 aluminum electrolytic and B32 film catalog, the N87 / N95 / N97 / PC40 / PC44 / PC47 ferrite core inventory, the full MLK / TFM / MLZ / VLS / SPM inductor portfolio, and the complete InvenSense ICM / MPU, Micronas HAL, Chirp CH, and TDK-Lambda HWS / RWS / DPP line cards — plus legacy EPCOS-branded MLCC and thermistors, Densei-Lambda / Lambda pre-acquisition PSUs, older Micronas HAL 8xx Hall sensors, and 3C90 / 3C94 legacy ferrite grades on request. Date codes, factory of manufacture, and full traceability documentation on every quote.

TDK quote & sourcing FAQ

What TDK products does Hybrid Electronics quote most often?

C-series and CGA automotive MLCC, EPCOS B41xxx / B43xxx aluminum electrolytics, EPCOS B32xxx film and DC-link capacitors, B57xxx NTC thermistors, N87 / N95 / PC40 ferrite cores, MLK / TFM / VLS / SPM SMD power inductors, InvenSense ICM-20948 / ICM-42688-P IMUs, Micronas HAL 15xy / HAL 24xy Hall sensors, and TDK-Lambda HWS / RWS / DPP industrial PSUs are our highest-volume TDK quote categories. Legacy EPCOS-branded MLCC and thermistors, MPU-6050 / MPU-9250 discontinued IMUs, older Densei-Lambda and Lambda-branded PSUs, and Micronas HAL 8xx Hall sensors are steady low-volume sourcing lines for medical, defense, and locked-BOM industrial customers.

Can Hybrid Electronics source TDK parts in allocation?

Yes. When TDK MLCC (especially CGA automotive), EPCOS aluminum electrolytic, film DC-link, or B57xxx thermistor allocation tightens — typically driven by EV inverter builds, solar / storage inverter growth, or industrial drive rebuilds — we quote from OEM excess, contract-manufacturer surplus, and traceable secondary channels rather than waiting on a 30+ week authorized-distribution lead time. Include target part number, quantity, date-code window, and any packaging constraints (7in vs 13in reel, tray, ammo pack) and we return an availability window and quoted price the same business day.

Do you carry AEC-Q200 automotive TDK parts?

Yes. We regularly source AEC-Q200 TDK parts including CGA-series auto MLCC, CEU wide-terminal high-vibration auto MLCC, B32774 auto DC-link film capacitors, B57560 auto NTC thermistors, B82789 / B82790 auto CAN / LIN CMCs, SPM molded auto-grade power inductors, and Micronas HAL 24xy AEC-Q100 auto Hall sensors. TDK's Japanese, Hungarian, and German fabs are IATF 16949 certified with PPAP submission on request. Ask us to match a specific date-code range, temp grade, packaging, or termination style on your RFQ.

Do you stock legacy EPCOS, Densei-Lambda, Micronas, and InvenSense (MPU) parts?

Yes. We routinely source EPCOS-branded MLCC, aluminum electrolytic, film, and PTC / NTC thermistors that shipped before the 2008 TDK integration, Densei-Lambda and pre-acquisition Lambda-branded industrial PSUs, Micronas HAL 8xx / 10xx / 11xx Hall sensors pre-TDK rebrand, and InvenSense MPU-6050 / MPU-9250 discontinued IMUs from OEM excess and CEM surplus. These families are common on locked-BOM industrial, robotics, medical, and defense builds where a form-fit-function replacement is not allowed.

Are your legacy TDK / EPCOS parts factory sealed and traceable?

Yes when available. Most of our OEM-excess and CEM-surplus TDK / EPCOS / TDK-Lambda / InvenSense stock is factory sealed with original date codes and full traceability documentation. For downgraded or partial-reel stock we disclose condition (open reel, tested-pull, refurbished) on the quote. Customers requiring MSL data, COO, DPAS-rated delivery, or full C of C should note that on the RFQ.

How fast is your TDK quote turnaround?

Same day for parts in stock — typically within 2 hours during business hours (9am to 6pm ET). Sourced quotes on out-of-stock parts return within 24 to 48 hours with an availability window. Email sales@hybridelectronics.com or call (407) 542-3995 to open an RFQ.

Is Hybrid Electronics an authorized TDK distributor?

No — we're an independent distributor and excess-inventory buyer sourcing from OEM excess, CEM surplus, and traceable secondary channels since 1995.
