Radial-Leaded PolySwitch Resettable PPTCs

Littelfuse Radial-Leaded Resettable PPTCs are designed to provide overcurrent protection for applications where space is not a concern, and resettable protection is preferred. With so many options in the radial-leaded PPTCs family, engineers can design with more flexibility. The components feature current ratings from 50mA to 15A, low resistance, and a fast time-to-trip. Higher voltage ratings (6V to 72V) allow for use in new applications. Littelfuse Radial-Leaded Resettable PPTCs are compatible with high-volume electronics assembly and can assist in meeting regulatory requirements.
