Bourns MF-MSMF Polymer PTC Resettable Fuses

Bourns MF-MSMF Series Polymer PTC Resettable Fuses provide circuit protection through Polymeric Positive Temperature Coefficient (PPTC) technology in surface-mount packages. These components deliver overcurrent protection with a self-resetting feature once fault conditions are eliminated. The design allows for low-profile installation and resists mechanical stresses in compact electronic assemblies. These devices support a maximum voltage of 60VDC, a maximum interrupt current of 40A, and an operating temperature range from -40°C to +85°C. The MF-MSMF fuses are suitable for networking devices, battery protection, and general electronic assemblies.
