The LITTELFUSE 0997010.WXN is a MINI blade fuse engineered for applications requiring a compact and reliable overcurrent protection solution. Designed for use in 42V systems, this fuse incorporates a rejection feature to ensure proper fuse selection and prevent accidental insertion of lower voltage-rated fuses. It offers a time-current characteristic consistent with the 32V MINI fuse, providing predictable protection. The fuse's construction includes Ag plated zinc alloy terminals and PA66 housing, meeting SAE J2077, SAE 2576, ISO 8820, and UL 248 standards. Its interrupting rating is 1000A at 58VDC, and it operates effectively within a component level temperature range of -40°C to +125°C and a system level temperature range of -40°C to +105°C.
