Active production — BOM-fit note
The TPSE476M020R0125: The 125 mOhm ESR at 20 V rated voltage means it handles ripple current in a DC-DC output filter or hold-up cap application without excessive self-heating — the ESR is low enough to keep the temperature rise within the molded-case limits under typical switching-regulator ripple.
Temperature range and deployment context
Rated for -55°C to 125°C operating temperature, this is an industrial/military-grade tantalum — suitable for outdoor telecom, engine-bay electronics, or avionics power rails that see wide thermal cycling. The molded case and surface-mount 2917 package keep the part stable on the board under vibration. The ±20% tolerance is standard for tantalum electrolytics in bulk decoupling roles — the capacitance drift with temperature and DC bias stays within the tolerance band, so the downstream regulator's phase margin is not compromised.
