TE CONNECTIVITY - RAYCHEM Radial Lead Resettable PolySwitch - 3.75A

The TE CONNECTIVITY - RAYCHEM Radial Lead Resettable PolySwitch is a compact, reliable, and self-resetting overcurrent protection device. Featuring through-hole mounting, it provides robust circuit protection for a wide range of sensitive electronics by automatically responding to fault currents and resetting once the fault is cleared and power is cycled. This eliminates the need for manual fuse replacement, significantly reducing maintenance time and costs.

Designed for precise voltage balancing and a stable hold current down to 50mA, with a high voltage rating of up to 72VDC, this device is ideal for integration into high-volume automated assembly processes. It offers a low initial resistance, contributing to minimal power loss during normal operation, and is compliant with stringent regulatory standards, including UL94V-0 flammability, ensuring safety and material stability.

A key advantage is its rapid trip time, responding to overcurrent events in seconds to protect downstream components from damage. The device is constructed with tin-plated copper leads for excellent solderability and reliable electrical connections. Its radial leaded design and standard pin spacing facilitate straightforward PCB integration, making it a versatile and dependable choice for protecting circuit boards across numerous demanding applications.
