F4901 1.1a 24v Schematic

, you're likely dealing with a protection component on a 19V-24V power rail. What it is: A resettable PTC fuse or a fast-acting surface-mount fuse. Common Symptom:

The F4901 is a Polymeric Positive Temperature Coefficient (PPTC) device. Unlike a traditional glass fuse that "blows" and must be replaced, the F4901 increases its resistance dramatically during a fault, cutting the current to a safe level. Once the fault is removed and the power is cycled, it "resets" to a low-resistance state. Key Specifications: Hold Current ( Iholdcap I sub h o l d end-sub f4901 1.1a 24v schematic
