PTC Resettable Fuses

The PTC Resettable Fuses are a type of safety device that serves as a special type of overcurrent protection device. The PTC Resettable Fuses are also known as Polymeric Positive Temperature Coefficient (PPTC) Fuses. These devices are capable of providing overcurrent protection in a wide variety of consumer, industrial and automotive applications.

LVR005S application field and working principle

The LVR005S PTC Resettable Fuse is a low-cost, surface mount resettable fuse with 5mm x 5mm package dimensions. This PTC resettable fuse is designed to break high-current short circuits to protect electronic systems from being damaged and to limit fire hazards. The LVR005S has a wide variety of applications, including automotive, consumer electronics, home appliances and industrial equipment.

The working principle of the LVR005S is quite simple. This device contains a specially engineered thermoplastic which will expand in response to increased temperature. Once the current passes through the PTC Resettable Fuse, the temperature of the thermoplastic rises and causes the plastic to expand. This expansion creates a permanent break in the circuit and cuts off the current.

When the current is cut off, the system will reset the PTC Resettable Fuse to its original state, allowing the current to pass through once again. The reset is triggered by the cooling of the thermoplastic. As the temperature decreases, the thermoplastic will shrink back to its original shape and reset the device.

The LVR005S is designed for use under harsh conditions and offers excellent protection against high-current short circuits. This device is tested to handle up to 30 volts and 15 amps of current. It is the perfect solution for consumer, automotive and industrial electrical systems which need reliable, resettable overcurrent protection.

The LVR005S is RoHS compliant and UL certified. It is a great choice for applications that require reliable protection from high-current short circuits, and which require a small-size, low-cost solution.
