LITTELFUSE PolySwitch miniSMDC Resettable Fuse 24V DC 1.5A

The LITTELFUSE PolySwitch miniSMDC Resettable Fuse is a surface-mount device (SMD) designed to save valuable board space and reduce costs, whilst offering higher voltage ratings for broader application use. This resettable PPTC (Polymeric Positive Temperature Coefficient) device is fully compatible with high-volume electronics assembly and assists in meeting strict regulatory requirements.

Featuring a robust construction with 100% matte tin over a nickel underplate, this fuse ensures reliable solderability and performance. It provides a holding current of 1.5A and a trip current of 3A, with a fast time-to-trip of 1.5 seconds to protect sensitive circuits from overcurrent faults. The device can handle a maximum current rating of 20A and operates reliably across a wide temperature range from -40°C to 85°C.
