The BK30-900 with PTC Resettable Fuses DO-214 RoHS is an electronic component manufactured by Yageo. It is a resettable polymeric positive temperature coefficient (PPTC) fuse. The device is designed to protect against short circuit, over current and/or over voltage conditions and is easily mounted using standard surface mount technology. The package is RoHS compliant and is qualified to AEC-Q200 automotive standards. Operating temperature range is -55°C to +125°C and the rated voltage is 9V. The rated current of the fuse is 900mA. The resettable nature of the device allows it to reset when the external fault condition is removed. This is a ‘green’ device, making it an ideal choice for consumer electronics applications where design size, cost and thermal dissipation are important factors.
