PTC Resettable Fuses are an important part of circuit protection and are used to provide reliable and cost-effective circuit protection. The RUSBF185 is a polymeric positive temperature coefficient (PPTC) fuse designed for providing both over-current and over-temperature protection. It is an ideal choice for start-up and resettable protection of industrial equipment, telecommunications, consumer electronics, and automotive electronics. The RUSBF185 is designed to trip fast during a surge or over-current event. After the fault is cleared, the fuse can be reset manually, eliminating the need to replace the fuse. The RUSBF185 has a low failure rate and provides excellent protection against short circuits, overloads, and overheating. The working principle behind the RUSBF185 is based on the fact that polymeric materials, like plastic and rubber, have special electrical properties. When an electric current is passed through these materials, the temperature of the material rises. This is known as the PTC (positive temperature coefficient) effect, and it is the basis for the fuse\'s reliable operation. At normal current levels, the RUSBF185 remains in a reset mode and acts like an open switch. If the current exceeds the set threshold, the temperature of the fuse increases and the thermal fuse trips. This interrupts the flow of electricity and reduces current to a safe level, protecting the connected equipment from damage.The RUSBF185 is designed for wide range of applications. It can be used as an over-current protector in lithium ion batteries, as an over-temperature protector for industrial control systems and motor controllers, and as an inrush current limiter for LED lighting and florescence ballast. It is also used in telecommunications, consumer electronics, and automotive electronics. The RUSBF185 is also popular for protecting junction boxes from voltage spikes and surges. The RUSBF185 is easy to install. It is designed with a 2.8mm x 4.2mm ultra-small footprint to fit into tight spaces. It is also RoHS compliant, withstanding temperatures of up to 125°C and is fully recyclable.The RUSBF185 is a reliable and cost-effective solution for over-current and over-temperature protection. Its small size, low power consumption, and ability to be reset make it an ideal choice for a wide range of applications. Whether you need to protect a single circuit or an entire system, the RUSBF185 is a great choice for reliable circuit protection.
