22 µF, 35 V, 200 mOhm ESR — bulk decoupling in a 2917 footprint
The TPSE226M035R0200V: The 200 mOhm ESR at 100 kHz is the figure that governs ripple current handling and filtering effectiveness — lower ESR means less self-heating and better high-frequency decoupling in a power rail. This is the standard footprint for a bulk tantalum cap on a dense PCB — the E case gives you the capacitance and voltage rating without taking up more board real estate than necessary.
Full military temp range and 2000-hour endurance at 125°C
Operating from -55°C to 125°C, this cap covers the full military temperature band — it works in outdoor telecom, engine-bay electronics, and industrial control where the ambient swings wide. The 2000-hour lifetime at 125°C means it survives sustained high-temperature operation without premature failure, which is the typical wear-out mechanism for tantalum electrolytics. The molded construction and general-purpose feature set make it a drop-in replacement for many 22 µF / 35 V tantalum positions in existing BOMs. No special derating curve needed beyond the standard tantalum voltage derating practice (typically 50% for reliability).
Active production — no end-of-life pressure for this BOM line
For a procurement decision, that means no last-time-buy clock ticking, no scramble for a replacement before the line goes dark. This part is a standard catalog item in the TPS series, so supply continuity is predictable through authorized and independent channels.
