Littelfuse 3425L Series PolySwitch Resettable PPTCs
Littelfuse 3425L Series PolySwitch Resettable Polymeric Positive Temperature Coefficient (PPTC) offers surface-mount overcurrent protection for high-voltage devices that require resettable protection. The 3425L surface mount PPTCs have a low-profile design, provide a fast response to fault currents, and are RoHS compliant. These devices have a dissipated power rating of 2.5W and are compatible with high-volume electronics assembly. The 3425L series resettable PPTCs operate over a temperature range from -40°C to +85°C and a resistance range from 0.01Ω to 0.2Ω. These PPTCs are ideal for various applications, including automotive electronic control module protection, IEEE 1394 port protection, low-voltage telecom equipment protection, and portable electronics.
