ekThe A72-300 with PTC Resettable Fuses Through Hole RoHS from JDTek is an electronic component used for protecting circuits from undesirable overcurrent conditions. This component is designed with polymeric positive temperature coefficient (PPTC) technology and incorporates a bidirectional positive temperature coefficient current sensing element and a capacitor. It provides high accuracy current protection with a short response time and provides electronic circuit protection to AC/DC, IT, medical, LED lighting, power supply, and other applications where overcurrent protection is required. The component also features RoHS (Restriction on the use of hazardous substances in electrical and electronic equipment) compliant tin-plated lead-free and flame retardant material.
