The 8 Ohm ESR is a design parameter: higher ESR damps ringing in power-supply filters but also contributes self-heating under ripple current. For a 1206 case, the 25 V rating leaves margin above the rail voltage, reducing the risk of field failure from voltage surges. ## 1206 footprint and temperature range The 1206 (3216 Metric) case measures 3.20 mm x 1.60 mm with a seated height of 1.20 mm.","metaTitle":"TAJS105K025RNJ KYOCERA AVX Molded Tantalum Capacitor 1 µF","metaDescription":"TAJS105K025RNJ from KYOCERA AVX: Molded tantalum capacitor, 1 µF, 25 V, ±10%, 1206 case, -55°C to 125°C, 8 Ohm ESR.
