330 µF, 6.3 V, 100 mOhm — the ESR drives the fit
The TPSE337K006R0100: That ESR figure is the parameter that decides whether this cap works in a DC-DC converter output filter — lower ESR means less ripple voltage at the same ripple current, so the downstream regulator sees a cleaner rail.
Temperature range and lifecycle
A power supply in an outdoor telecom cabinet or an engine-bay ECU sees ambient well above 85°C; this cap holds its rated capacitance and ESR through that range.
Sourcing and availability
Available in Tape & Reel (TR) for volume production or Cut Tape (CT) for prototype runs.
