3.3 µF, 25 V, 1 Ohm ESR — molded tantalum in 1206
The TPSA335K025R1000: This is a KYOCERA AVX TPS series molded tantalum capacitor rated at 3.3 µF with ±10% tolerance and a 25 V DC voltage rating. The 1 Ohm ESR at 25°C sets the ripple current ceiling — for a 100 kHz switching regulator output, the self-heating stays manageable below 200 mA RMS ripple. The 1206 (3216 Metric) case is a standard footprint for reflow assembly, with a seated height of 1.80 mm max.
