330 µF, 10 V, 40 mOhm — the low-ESR bulk decoupling fit
The TPSE337M010R0040: That ESR figure is the headline parameter — at 40 mOhm this part sits in the low-ESR band for a 330 µF tantalum, meaning it handles ripple current without excessive self-heating and keeps the voltage ripple low on a 10 V rail.
Rated for -55°C to 125°C, this capacitor covers the full military temperature range — it operates in an engine bay, an outdoor radio head, or a satellite power bus without derating for ambient extremes. The molded case construction means the epoxy encapsulation resists mechanical stress and moisture ingress better than a conformal-coated chip, though it is not hermetically sealed. Surface-mount reflow profile follows standard tantalum recommendations — preheat ramp rate under 3°C/s to keep the internal anode from thermal shock.
Active lifecycle — no end-of-life signals on this line
The TPS series is a standard molded tantalum line with broad distribution coverage, so this part is sourced through franchised channels and independent surplus equally. No official successor or cross-reference exists because none is needed; the part is current production.
