PTC Resettable Fuses
PTC Resettable Fuses, also known as "Polyfuse," are specialized fuses that are used primarily in electronics and other devices. These fuses are designed to trip and then reset themselves once the current returns to a nominal level. The PTC resettable fuse is made up of two parts; a coil and a ceramic material. PTC fuses, due to their inherent characteristics, are well-suited for a variety of electronics applications, including port protection, power supplies, and component protection.
1206L450SLWR Application Field and Working Principle
The 1206L450SLWR is a PTC resettable fuse with a ceramic body and a round nickel-plated plated pin anchored to a silver-plated copper disc. The PTC Resettable fuse operates through a proprietary lockout mechanism which functions to repeatedly protect against over-current and short circuit events. The 1206L450SLWR resettable fuse features excellent thermodynamic stability with a high overload current capability, a fast short-circuit response, a low voltage rating, and a long service life.
The 1206L450SLWR resettable fuse is designed for use in electronic applications such as signal and power protection for automotive, communications, industrial, medical, and consumer electronics. The fuse can be used in DC systems with a working voltage up to 24V, with an operating temperature range from -55°C to +85°C. The fuse is RoHS compliant and is UL recognized, VDE approved and CUR certified.
In normal operation, the 1206L450SLWR resettable fuse is in a low resistance state, allowing electric current to flow through the device unhindered. When an over-current or short-circuit condition occurs, the ceramic body rapidly increases in resistance, which limits the current to a safe level. Once the current drops sufficiently and the device cools, the PTC resettable fuse returns to the original low resistance state, allowing current to again flow through the device.
Conclusion
The 1206L450SLWR PTC Resettable Fuse is specifically designed for use in electronic devices with a working voltage up to 24V. This fuse has excellent thermodynamic stability with a high overload current capability, a fast short-circuit response, and a long service life. The 1206L450SLWR is RoHS compliant and is UL recognized, VDE approved and CUR certified. It is an ideal choice for applications such as signal and power protection for automotive, communications, industrial, medical, and consumer electronics.
