The BSMD0805-005-15V is a surface-mount PTC (positive temperature coefficient) resettable fuse with 0805 RoHS certification from BHFUSE. It is a highly reliable, overcurrent protection device that is designed to protect against overload and short circuit current conditions. The device is composed of a positive temperature coefficient (PTC) thermistor located in the device case. When current through the device exceeds its rated value, the thermistor rapidly heats up, creating an approximate open circuit that trips the device. When the current decreases, the PTC cools off and allows the current to resume, resetting the device. The BSMD0805-005-15V has a working voltage of up to 15V and a rated current of 5A. It also has a ceramic case and is lead-free and RoHS compliant. The device is ideal for applications that require overcurrent protection, including automotive, industrial, and consumer electronics.
