DC cold resistance is 0.75 Ohms, a value that affects the voltage drop across the fuse at rated current — at 250 mA the drop is under 0.2 V, negligible for most 3.3 V and 5 V rails. ## Melting I²t and operating temperature Melting I²t is 4E-05 A²s, a low value consistent with a fast blow fuse that opens quickly on overcurrent — important for protecting sensitive ICs where the energy let-through must be minimal.","metaTitle":"F1206A0R25FSTR KYOCERA AVX Accu-Guard® 250 mA Fast Blow Fuse","metaDescription":"KYOCERA AVX F1206A0R25FSTR Accu-Guard® series, 250 mA fast blow surface mount fuse in 1206 package.
