RUEF185 PTC Resettable Fuse 30V 1.85A Through Hole
The RUEF series is a radial-leaded, PolySwitch® resettable fuses (PPTCs) providing reliable overcurrent protection. These components automatically switch to a high-resistance state during a fault and reset once the condition is cleared and power is cycled. Rated for 30V, they offer a versatile and maintenance-free alternative to traditional single-use fuses for a wide variety of electronic applications.
Features
- RUEF series is for balance of voltage rating (30V) and hold current.
- Lead-Free and Halogen-Free.
- Resettable Overcurrent Protection: Automatically resets after a fault condition is cleared, reducing maintenance and replacement costs.
- Fast Time-to-Trip: Quickly interrupts excessive current flow to protect downstream components.
- Low Resistance: Features a low initial resistance, minimizing its impact on circuit performance under normal operating conditions.
