100 µF, 6.3 V — the bulk cap for low-voltage rails
The TPSW107K006R0100: The 100 mOhm ESR is the spec that governs ripple current handling — at this impedance, the cap can absorb a few hundred mA of AC ripple before self-heating becomes a derating concern. The ±10% tolerance is standard for tantalum electrolytics — the actual capacitance at 6.3 V bias will be near the nominal value, unlike MLCCs which lose 50-70% under DC bias. That stability makes this a predictable choice for timing circuits or filter poles where the absolute capacitance matters.
Temperature range and board-fit
Rated for -55°C to 125°C operation, this capacitor spans the full industrial and military temperature envelope. Available on tape and reel (as well as cut tape), it feeds directly into pick-and-place lines without manual kitting. The molded construction gives better mechanical robustness than conformal-coated chips — less risk of corner cracking during board flex or thermal cycling.
