RUEF090 PTC Resettable Fuse 30V 900mA Through Hole
The RUEF Series (30 V) are radial-lead, resettable PTC (Polymeric Positive Temperature Coefficient) fuses engineered to provide reliable overcurrent protection across a wide range of consumer, industrial and communication electronics. RUEF devices automatically limit fault currents by increasing resistance when a trip occurs and return to a low resistance state after cooling, reducing downtime and maintenance costs compared with single-use fuses.
Features
- Resettable and single-use overcurrent device.
- RUEF series is for balance of voltage rating (30V) and hold current.
- Device is compatible with high-volume electronics assembly.
- Lead-Free and Halogen-Free.
