In a 35 V rail decoupling a switching converter, the ripple current through the ESR raises the internal temperature; the 125°C ceiling provides margin for derating, but the designer should calculate I²R heating against the ambient profile.","metaTitle":"TPSB155M035R2500 KYOCERA AVX Molded Tantalum Capacitor","metaDescription":"Active TPS series molded tantalum capacitor, 1.5 µF ±20%, 35 V rated, 2.5 Ohm ESR, -55°C to +125°C.
