10 µF, 16 V, 800 mOhm — the ESR drives the decoupling decision
The TPST106K016H0800: The 800 mOhm ESR is the parameter that governs ripple current handling and self-heating in power rail decoupling — a lower ESR means less voltage ripple for a given load transient, but also less internal temperature rise under AC ripple. For a 16 V rail with a 100 kHz switching regulator, this ESR keeps the capacitor's ripple current within its thermal budget without oversizing the package.
Rated for -55°C to 125°C, this part covers the full industrial temperature range — suitable for outdoor telecom, automotive under-hood (with appropriate derating), and engine-bay enclosures. The molded case provides mechanical protection and consistent standoff height for cleaning under the component.
