68 µF, 10 V, 100 mOhm ESR — D-case tantalum for power-rail decoupling
The TPSD686M010R0100: The 100 mOhm ESR is the key figure for bulk decoupling: it sets the ripple current capability and self-heating under AC load. A lower ESR means the cap can handle higher ripple without exceeding its internal temperature rise, which is critical for output filtering on switching regulators or bus capacitors near high-frequency converters.
Rated for -55°C to 125°C operating temperature, this capacitor spans the full industrial and military temperature envelope. The 100 mOhm ESR is specified at 25°C and 100 kHz; at elevated temperatures the ESR rises slightly, but the tantalum dielectric's stability keeps the capacitance within ±20% across the range. The ±20% tolerance is standard for tantalum electrolytics — the capacitance at 10 V bias will be near the nominal value, but derating to 50% of rated voltage (5 V or less) is recommended for reliability in long-life applications, as tantalum capacitors are sensitive to voltage stress.
Active production — sourcing for BOM fill
Because this part is molded and tape-and-reel packaged, it ships in standard EIA-481 embossed carrier tape suitable for automated assembly. The D case is a common size, so reel quantities are typically 500 or 1000 pieces per reel — confirm the reel quantity at quote to match your batch size.
