68 µF at 16 V — the ESR drives the decoupling decision
The TPSY686K016R0150: That ESR figure is the spec that determines ripple current handling and transient response in a DC-DC converter output filter or a processor core rail — lower ESR means less self-heating and better high-frequency decoupling. The ±10% tolerance holds the capacitance within a tight window for filtering applications where the corner frequency needs to stay predictable across temperature and aging.
Temperature grade and package footprint
Rated for -55°C to 125°C, this capacitor covers the full industrial and military temperature envelope — suitable for engine-bay electronics, avionics power supplies, and outdoor telecom equipment where the ambient swings wide. This is a standard tantalum footprint shared across multiple manufacturers, so the PCB land pattern is well-established and the part drops into existing layouts without a pad revision. The Y case code (manufacturer size code) corresponds to this specific 2917 footprint and height — verify the code against your assembly house's pick-and-place tape dimensions before committing the reel.
