PTC Resettable Fuses, also called Polymeric Positive Temperature Coefficient (PPTC) Fuses, are becoming increasingly popular due to its capability of offering current protection for electronic products and personal devices. The RUSBF160-AP is one of the most widely used variants of PTC Resettable Fuses, and can be used in a variety of applications. In this article, we will take a look at the applications and the basic principles of operation of the RUSBF160-AP.

RUSBF160-AP is a one-time-programmable PTC Resettable Fuse. It is ideal for applications where flexibility in overcurrent protection is needed, with its adjustable trip current ranging from 0.05A to 1.25A. It is available in different packages such as surface mount, through-hole and dual in-line. It can also be used to protect system, battery and cable assemblies from over-current related problems.

One of the most common applications of RUSBF160-AP is in power supplies, where its programmable parameters can be set to protect the power supply from short circuits by limiting the current flow. It can also be used in networking equipment such as routers, switches and hubs, to help prevent damage by over-current or short circuit events. Additionally, the RUSBF160-AP can be used in mobile devices such as smartphones and tablets, to protect the device from over-current and overcharging.

The basic working principle of the RUSBF160-AP is that it contains a Polymeric Positive Temperature Coefficient (PPTC) thermistor which acts as a current limiter. When the current exceeds the predetermined level, the PPTC thermistor will begin to increase in temperature, eventually reaching the melting temperature of the PPTC material and opening the circuit. When the fault condition is removed, the PPTC thermistor will cool down to its normal operating temperature, allowing the circuit to reset and operate normally again.

The RUSBF160-AP is an ideal choice for applications where over-current protection and flexibility is needed. It is an effective and reliable solution for protecting electronic devices from short circuit and over-current related problems. Its adjustable trip current feature makes the RUSBF160-AP very versatile, and it can be used for a variety of applications with its different form factors and adjustable trip current. Its cost-effectiveness and small form factor makes it an ideal choice for protecting personal devices, electronic systems and battery assemblies.
