PTC Resettable Fuses are a type of fuse that are designed to open in an overcurrent situation and reset, or automatically restore to an operational state. The RUSBF090-AP is a Polymeric Positive Temperature Coefficient (PPTC) device, designed specifically as an overcurrent protection device for the mobile market.

This PTC fuse, also known as a polyfuse, is ideal for protecting high-end electronic devices from short-circuit damage and over-current conditions. Polyfuses are designed to significantly reduce the risk of damage from an over-current condition compared to other types of fuses or protective devices. It will trip in a fraction of a second in the case of an over-current situation, and then reset when the current decreases, allowing the device to continue to operate normally.

In terms of RUSBF090-AP application field, this fuse is especially suitable for the protection of Lithium-ion Battery Packs used in a wide variety of portable electronics from smart phones, tablets, laptop computers, GPS navigation devices to digital cameras. The device not only protect against shorts, but also provides protection against high temperature and overcharge/overdischarge. This makes it a great choice for devices where the risk of overheating and battery damage is a concern.

The working principle of the RUSBF090-AP device is based on its PTC resistor. When the current passes through the PTC, its resistance increases, effectively protecting against an over-current condition. The resistance of the RUSBF090-AP device can be adjusted depending on the desired current limit. The device is designed to remain in a “reset” state until the current exceeds the set limit, at which point the device will trip and open the circuit. When the current drops to a safe level, the device will reset and allow the circuit to become operational again.

In addition to its high current protection, the RUSBF090-AP can also serve the purpose of low impedance current shunt and voltage clamp. The device can also serve as a fuse for an electronic device. The device is rated to two different voltage ratings, making it very versatile in many applications.

Overall, the RUSBF090-AP is a reliable and cost effective solution for protecting Lithium-ion cells and other high-end electronic devices from overheating and other overcurrent conditions. The device is easy to use and is designed to operate over a wide temperature range, making it a great choice for many different applications.
