Bulk decoupling for low-voltage rails
The TPSE477M006R0100V: The 100 mOhm ESR at 100 kHz limits the ripple voltage: for a 1 A ripple current, the ESR drop is 100 mV, which is within the tolerance of most POL converters. Fits the standard tantalum land pattern for this case size; no layout surprise.
Temperature profile and life expectancy
Rated for 2000 hours at 125°C with the full rated voltage applied. The -55°C to 125°C operating range covers military temperature extension — this cap lives through the cold start and the hot soak in an engine bay or an outdoor radio head. ±20% tolerance is the standard for tantalum electrolytics in this class — the capacitance change over temperature and DC bias is accounted for in the derating guideline. Plan for 80% of rated voltage maximum for best reliability.
For high-reliability or automotive builds, confirm the buyer's own derating and screening requirements.
