Manufacturer profile
Hybrid Electronics sources Littelfuse circuit protection and power semiconductors — 3AG / 5x20mm / 6x32mm cartridge fuses, Nano2 & 0805L surface-mount fuses, ATO / Mini / Micro2 automotive blade fuses, POLYFUSE PTC resettables, SP-series TVS diode arrays, MOV varistors and gas discharge tubes, Hamlin reed switches, IXYS-heritage SCRs / IGBTs / MOSFETs, LSIC SiC MOSFETs, Clare photo-MOSFET solid-state relays, U.S. Sensor thermistors, Cole Hersee commercial-vehicle switches, C&K precision switches, and Symcom / SSAC motor-protection controllers — from current stock to obsolete Slo-Blo, Wickmann heritage, and pre-2018 IXYS parts. Same-day quotes and traceable OEM excess since 1995.
Littelfuse, Inc. (NASDAQ: LFUS), founded in 1927 by Edward V. Sundt in Chicago, Illinois, is the global leader in circuit protection — the company's original invention was the small-diameter "little fuse" for early automotive and radio electronics. With approximately 17,000 employees worldwide and roughly $2.3 billion in annual revenue, Littelfuse now spans three business segments: Electronics (fuses, TVS diodes, MOVs, PTCs, ESD suppressors, gas discharge tubes, reed switches, sensors, and precision electromechanical switches), Industrial (power semiconductors, industrial fuses, and protection relays), and Transportation (automotive, commercial-vehicle, and off-highway blade fuses, switches, and sensors).
Littelfuse's product breadth reflects decades of aggressive acquisition — Wickmann-Werke (1998, European ceramic and Slo-Blo fuse heritage), Heinrich Industries (1998), Efen (1999), Fusetel (2000), Startco (2007, motor protection), Cole Hersee (2010, commercial-vehicle switches and relays), Accel AB (2011, automotive sensors), Selco (2011, reed switches), Terra Power Systems (2010, became the Hamlin brand), Hamlin, Inc. (2013, reed switches and sensors), U.S. Sensor Corp. (2014, thermistors), Menber's SpA (2015, commercial-vehicle switches), Monolith Semiconductor (2016, SiC MOSFET technology), Symcom / SSAC (2017, motor protection controllers), the massive IXYS Corporation (2018 — SCRs, thyristors, MOSFETs, IGBTs, fast-recovery diodes, plus the Clare solid-state relay line and IXYS Integrated Circuits Division), Carling Technologies (2022, switches), and C&K Switches (2022, precision electromechanical and Cherry-heritage switches).
Hybrid Electronics has stocked and quoted Littelfuse excess since 1995. We support customers who need obsolete pre-2005 3AG glass cartridge fuses, legacy Wickmann Slo-Blo lot codes, pre-2018 IXYS SCR and IGBT revisions, discontinued Hamlin MRPR reed relays, early RXEF PPTCs, obsolete Cole Hersee 24 VDC contactors, legacy Clare LAA127 solid-state relays, C&K Alco-branded switches from before the 2022 Littelfuse acquisition, early PGB ESD suppressors, obsolete SP0304 TVS arrays, and pre-2017 Symcom pump switches — the parts still keeping motor drives, medical equipment, defense electronics, telecom power, and industrial control systems in service after authorized distributors have moved on.
Our Littelfuse line card spans the full circuit-protection and power-semiconductor portfolio — from current AEC-Q-qualified automotive fuses and SiC MOSFETs to legacy Wickmann, Hamlin, Clare, Cole Hersee, and C&K acquisitions still supporting long-lifecycle industrial, defense, and transportation BOMs.

Automotive AEC-Q-qualified fuses and semiconductors, MIL-QPL parts, and traceable date-code stock available — specify your target date-code window, packaging (tape & reel, ammo, tube, bulk), and any lot-traceability requirements on the RFQ.
Littelfuse's product line spans nearly a century and 18+ acquired brands — and legacy families still ship into defense, medical, industrial motor drives, telecom, and commercial-vehicle BOMs long after authorized channels move on. Hybrid Electronics sources these end-of-life and hard-to-find Littelfuse parts from OEM excess, contract-manufacturer surplus, and traceable secondary channels:
Send an RFQ with quantity, target date-code range, packaging preference, and any traceability requirements (COO, MSL, factory sealed, MIL QPL) — we return same-day availability from stock or an ETA from our sourcing network.
3AG (0313), 5x20mm (0217/0218), and Nano2 (0451/0466) cartridge and SMD fuses; ATO / Mini / Micro2 automotive blade fuses; POLYFUSE PTC resettables (60R, 250R, 1210L); SP-series TVS diode arrays and SMBJ / SMCJ discrete TVS; V275LA MOV varistors; Hamlin reed switches; and IXYS-heritage IGBTs, MOSFETs, and SCRs are our highest-volume Littelfuse quote lines. Clare photo-MOSFET SSRs, LSIC SiC MOSFETs, Cole Hersee automotive relays, C&K precision switches, and Symcom motor-protection controllers are steady sourcing lines across industrial, defense, telecom, and commercial-vehicle customers.
Yes — we regularly quote AEC-Q-qualified 0287 ATO, 0297 Mini, 0483 Micro2, and 0454 Micro3 automotive blade fuses; AEC-Q100 / Q101 IXYS-legacy MOSFETs and IGBTs; and AEC-Q200 POLYFUSE PTCs and MOV varistors for tier-1 automotive and EV builds. Note the specific automotive suffix and date-code window on the RFQ — part-marking and lot-traceability requirements are commonly enforced by tier-1 QMS audits.
Yes — original IXYS-branded SCRs, IGBTs, MOSFETs, and Clare / IXYS ICD solid-state relays; Hamlin MRPR reed relays and 59125-series reed sensors; and Cole Hersee 24 VDC solenoid contactors and battery-disconnects from before their respective Littelfuse acquisitions are steady sourcing lines. Provide the original independent-brand part number and any lot-date-code requirement and we return stock and cert package on the quote.
Yes when available — most of our OEM-excess and CEM-surplus Littelfuse stock is factory sealed with original date codes, moisture-barrier bags (for SMD Nano2 and TVS arrays), ammo-pack packaging (for blade fuses), and full lot-traceability paperwork. For downgraded stock we disclose condition (open reel, partial reel, cut-tape, opened ammo, tested-pull) on the quote. Customers requiring MSL data, COO, or DPAS-rated delivery should note it on the RFQ.
Same day for parts in stock — typically within 2 hours during business hours (9am–6pm ET). Sourced quotes on out-of-stock or obsolete parts return within 24–48 hours with an availability window. Email sales@hybridelectronics.com or call (407) 542-3995 to open an RFQ.
No — we're an independent distributor and excess-inventory buyer sourcing from OEM excess, CEM surplus, and traceable secondary channels since 1995.
