It is rated for 32 VDC and can interrupt fault currents up to 50 A at that voltage, which covers most low-voltage DC rail protection needs in telecom, industrial control, and consumer electronics. The melting I²t of 0.009 is the energy required to open the fuse — a low value that means it responds quickly to short-duration overcurrents, making it suitable for protecting sensitive circuits where fast clearing is needed. ## DC cold resistance and operating range DC cold resistance is 0.15 Ohms, which sets the voltage drop and self-heating under normal load. At 1.25 A, the I²R loss is about 0.23 W — negligible for most boards, but worth checking if the fuse sits in a high-ambient or tightly packed area.","metaTitle":"F1206A1R25FWTR KYOCERA AVX 1.25A Fast Blow Fuse 1206","metaDescription":"KYOCERA AVX Accu-Guard® F1206A1R25FWTR: 1.25 A fast-blow fuse, 32 VDC, 50 A breaking capacity, 0.009 I²t, 1206 SMD.
