Active production — BOM-fit note
The TPSY227K006R0100: The 100 mOhm ESR at 100 kHz is the figure that governs ripple current handling — for a 6.3 V rail, the ripple current capability at 85 °C is roughly 1.1 A RMS, limited by the self-heating from this ESR.
Case size and board footprint
The surface-mount footprint matches the standard 2917 land pattern — the anode pad on the long side, cathode on the shorter side, with the polarity mark on the top face.
Temperature grade and derating
Rated for -55 °C to +125 °C operation, the TPSY227K006R0100 spans the full industrial temperature range. At 125 °C the applied voltage must be derated to two-thirds of the rated 6.3 V — a standard derating practice for MnO₂ tantalum capacitors to maintain reliability against dielectric breakdown.
