PTC Resettable Fuses: RUEF160S

RUEF160S, a PTC (Positive Temperature Coefficient) resettable fuse, is a circuit-protection device designed for protecting your design against surges and fault current. It can provide a low response time when opened due to over-current or over-temperature and then reset once the fault is corrected.

The applications of RUEF160S primarily are in storage devices such as USB sticks, flash memory drives, USB cards, and other such devices. This device also finds itself in many applications involving charging and discharging circuitry, such as laptop power supplies, medical devices, and more.

RUEF160S, being a PTC fuse, works on the principle of thermal expansion and contraction. When the fuse is in its normal working state, the flow of current induces a heating effect, which causes the fuse element to expand and constrict the current flow.

However, when the current exceeds the rated level, the circuit\'s temperature starts to increase, resulting in further expansion of the fuse element, which further restricts the current flow. This leads to further rise in the temperature, resulting in the activation of the circuit protection and opening of the fuse terminal.

Once the fault is rectified and the current is stabilized back to its normal level, the fuse element cools down, gradually allowing the flow of current and resetting the circuit. Thus, PTC resettable fuses can provide reliable, repeatable, and fast response times.

RUEF160S has several significant features that make it suitable for applications where quick response times are critical. It has a low power consumption of 0.05W, relatively high interrupt currents up to 3A, and a response speed of 10ms which allows it to quickly respond to fault situations.

The RUEF160S is mostly used in applications where rapid response time is essential, and a fail-safe reaction is necessary. It can be used in portable electronic devices such as cameras, chargers, laptop power supplies, and industrial control products. Furthermore, it is also used in medical and LED devices, providing excellent protection against over-current and over-temperature due to its resettable characteristics.

RUEF160S is easy to install and use, making it convenient for use in various applications. It has two terminals, one of which is the output terminal, and the other one is the input terminal. Moreover, it also has a red indicator light that glows when the fuse is in operation.

To sum up, PTC-RUEF160S is a high-quality, resettable fuse with several features that make it suitable for applications where fast response times are essential. It has a low power consumption, relatively high interrupt currents, and a response speed of 10 milliseconds, making it ideal for various applications. Moreover, it is easy to install and use for added convenience.
