PTC (Positive Temperature Coefficient) resettable fuses are protective devices designed to prevent overcurrent conditions by automatically resetting after a fault is cleared. These fuses contain a special polymer or ceramic material that increases its resistance significantly when exposed to excessive current, thereby limiting the current flow and protecting the circuit. Once the overcurrent condition is resolved and the fuse cools down, its resistance decreases, allowing normal current flow to resume. PTC resettable fuses are commonly used in electronic devices, power supplies, and automotive applications to provide reliable and self-resetting overcurrent protection. Trust Lisleapex to provide high-quality PTC resettable fuses that offer effective protection and durability for your electronic systems.
