PTC Resettable Fuses have a wide range of application fields and working principles. RUEF090S is an easy to install, rugged, and reliable fuse that is used in various applications. The PTC fuse is a self-resetting fuse that is designed to protect circuits from hazardous current levels. It can provide an effective and reliable protection against overcurrent faults and provide quick and automatic reset after the fault condition.

The PTC Resettable Fuses provide high current interrupting and overcurrent protection in applications such as consumer electronics, automotive electronics, digital equipment, and industrial control applications. It helps to ensure safe and efficient operation of the circuit. It is easy to install and can be used in both on-board and off-board fuse holders.

RUEF090S is designed to protect against overcurrents, overvoltages, and short circuits. The PTC component is designed to allow a certain amount of current through the device, when that current exceeds a predetermined value, the PTC begins to heat up. The heat generated by the PTC is used to open the circuit, stopping all current flow through the device. This quickly reduces the amount of energy flowing through the circuit, protecting the system from excessive currents.

The PTC resettable fuse is easy to use and does not require a large amount of maintenance or special installation. The thermistor element in the PTC exhibits a positive temperature coefficient, which means that as current through it increases, its resistance increases. This increases the thermal energy being dissipated and eventually opens the circuit.

Once the circuit is opened, a latched element in the PTC keeps the circuit open until the fault is cleared. A reset switch needs to be pressed to restore power flow in the circuit. The device also includes an active current limiter that limits the current in the circuit to the rated value, and a thermal shut-off mechanism that disables the device if it exceeds the rated temperature.

The PTC device is typically packaged in a sealed plastic body to prevent mechanical damage. The current and voltage ratings of the PTC fuse are determined by the size and resistance value of the PTC device, which are usually expressed in amperes and volts. The fuse is typically installed in circuit board designs where a wide variety of currents and voltages can be used.

RUEF090S are designed to limit potentially damaging over current and overvoltage conditions in a circuit. They are an ideal solution for protecting circuits against short circuits, power surges, and over current events. They are widely used in a variety of application fields including consumer electronics, automotive electronics, industrial control, aviation, and medical devices. They are also particularly well suited for use in circuit boards that are exposed to moisture and/or harsh environments.

The PTC Resettable Fuses provides effective protection against hazardous current levels and can help ensure safe and efficient operation of the circuit. Its simple installation, maintenance, and resetting capabilities make it an attractive solution for a wide range of applications. The device is reliable, rugged, and easy to install.
