10 µF, 16 V — TPS series molded tantalum in 1411 case
The TPST106K016R0800: The 800 mOhm ESR at 100 kHz is the figure that governs ripple current handling in a buck converter output or power rail decoupling — a lower ESR means less self-heating for the same AC ripple, and this value is typical for a general-purpose tantalum in this case size. The surface-mount package ships on tape and reel, compatible with automated pick-and-place lines.
Temperature range and operating environment
The molded construction provides mechanical protection against board flex and vibration, though the tantalum anode itself is polarity-sensitive — reverse bias or excessive inrush current can cause catastrophic failure, so the circuit design must respect the rated voltage and include a current-limiting source impedance. The TPS series is marked as general purpose, meaning it does not carry a low-ESR or high-reliability classification. For designs requiring tighter ESR control or surge current testing per MIL-PRF-55365, a different series from the same manufacturer would be specified. For standard decoupling and filtering where the 800 mOhm ESR is acceptable, this part is a direct fit.
Sourcing and lifecycle — active production
No official successor or pin-compatible cross-reference is needed — the part is the current offering. The manufacturer code T indicates the 1411 case size, which is a common footprint shared across multiple tantalum suppliers, simplifying second-sourcing if needed.
