RUEF400 PTC Resettable Fuse 30V 4A Through Hole

From the shop's description

RUEF400 PTC Resettable Fuse 30V 4A 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.
