Tantalum &
high-V caps.
Hybrid Electronics sources tantalum and high-voltage capacitors on allocation — Vishay, KEMET, AVX (Kyocera), Panasonic, EPCOS/TDK, Cornell Dubilier — for defense, aerospace, industrial power supplies, and long-qualification platforms where substitution isn't an option.

The 2026 tantalum & high-voltage capacitor shortage in one paragraph.
Tantalum is a raw-materials story on top of a defense demand story. Tantalum ore supply and refining capacity haven't kept pace with defense platform ramps, and 2026 lead times on solid tantalum (SMD chip and radial) and wet tantalum (hermetic, hi-rel) sit at 30–52 weeks on the tight P/Ns. High-voltage film and ceramic capacitors follow a similar allocation curve driven by grid, EV, and industrial power.
For MIL-PRF-55365 (SMD tantalum), MIL-PRF-39006 (wet slug tantalum), and MIL-PRF-49470 (high-V ceramic) qualified parts, redesign is rarely a real option — qualification cycles run 12–18 months and drop-in equivalents don't exist across manufacturers. We source the exact P/N against Tier 1 excess and defense-prime cancellations.
Tantalum capacitor sourcing.
Solid tantalum SMD (Vishay 293D, KEMET T491, AVX TAJ) and wet tantalum hermetic (Vishay 189D and 138D, KEMET T110 wet slug) are on formal allocation with the top-tier manufacturers. Polymer tantalum (KEMET T520, T525) similar. Defense-grade CWR series (MIL-PRF-55365 M-level and above) is spot-channel primary.
We source against defense-prime cancellations, industrial excess, and legitimate OEM overstock. Full manufacturer traceability, date codes, and MIL-PRF certificates of conformance where the source can provide them.
Common part families we source
- T491 · T495 · T520 (KEMET SMD)
- 293D · 592D · 789D (Vishay solid)
- TAJ · TCJ · TPS (AVX solid & polymer)
- T110 · T111 · T322 (KEMET wet slug)
- CWR06 · CWR09 · CWR11 (MIL-PRF-55365)
- M39006 wet-slug hi-rel
High-voltage film & ceramic sourcing.
High-voltage DC-link film capacitors (EPCOS/TDK B32774, Vishay MKP1848, Cornell Dubilier 947C) drive the EV and grid inverter demand. High-voltage ceramic MLCCs at 1kV, 2kV, and 3kV ratings (Murata GRM, TDK CGA HV series, KEMET C-series HV) follow.
We source these against EV Tier 1 excess and canceled utility-scale solar and wind builds. AEC-Q200 automotive grades on the same lane. Full documentation and spec match — DC-link and snubber capacitors are safety-critical and we don't substitute without engineering sign-off.
Common part families we source
- B32774 · B32778 (EPCOS/TDK DC-link)
- MKP1848 · MKP184X (Vishay film)
- 947C · 946C (Cornell Dubilier)
- GRM32 · GRM43 (Murata high-V MLCC)
- CGA9 · CGA11 (TDK high-V MLCC)
- C0G · X7R HV ceramic (KEMET)

Common questions.
Can you source MIL-PRF-55365 M-level tantalum?
Yes. Defense-grade CWR-series and M39006 wet slug are the tightest tantalum P/Ns we source. Full MIL-PRF certificate of conformance where the source can provide it. We prefer full BOM quotes with program name and cycle horizon for defense work.
What documentation comes with a hi-rel capacitor quote?
Manufacturer certificate of conformance, MIL-PRF slash-sheet reference, date code, country of origin, RoHS/RoHS-exempt status, and lot-level traceability. For defense programs we can also route testing (electrical, X-ray, hi-pot) through a partner lab.
Do you handle EV DC-link capacitor quotes?
Yes. EV traction inverter DC-link and DC fast-charger capacitors are a regular quote lane. AEC-Q200 documentation, spec match on capacitance/voltage/ESR, and current-handling paperwork on request.
Why is redesign rarely an option on tantalum?
Because qualification runs 12–18 months for defense and aerospace, and drop-in tantalum equivalents almost never exist across manufacturers — dielectric behavior, ESR, and voltage derating curves all differ enough that a substitute part triggers a full requal. Sourcing the exact P/N is nearly always cheaper.
