The MF-RX135-2 is a PTC resettable fuse with radial leads engineered for overcurrent protection in low-voltage applications up to 60V. This device features a hold current (Ihold) of 1.35 A at 23°C and a trip current (Itrip) of 2.70 A, with an initial resistance of 0.12 Ohms and a post-trip resistance of 0.19 Ohms. The fuse is constructed with cured, flame-retardant epoxy polymer insulating material meeting UL 94V-0 requirements and is RoHS compliant and halogen-free. It operates reliably across a temperature range of -40°C to +85°C with a maximum device surface temperature of 125°C in the tripped state. The MF-RX135-2 is ideal for protecting security and fire alarm systems, loudspeakers, and power transformers, offering automatic reset capability and reliable circuit protection without requiring manual intervention.
