PTC resettable fuses are electronic devices that provide over-current protection to electrical circuits and systems. The YQS8120 is a resettable fuse that is used to protect from over-currents and other power related issues. It is a bidirectional device with a trip current of 4.2A ± 30%.

The YQS 8120 is a polymeric positive temperature coefficient device, meaning it has a self-resetting capability. This device offers high current capability with a low hold current and fast response time. It can be used in many different applications as it is well suited for use in appliances such as washing machines, dryers, dishwashers, and HVAC systems.

The PTC resettable fuse YQS 8120 has two terminals, one for each direction. It is a two-wire device, meaning both polarity combinations are possible. It operates over a temperature range of -40°C to +125°C and has a maximum voltage rating of 250V DC. The fuse is 4.2A ± 30% trip current rating and a hold current rating of 0.1A.

The YQS 8120 resettable fuse is ideal for protecting electrical circuits in various low power applications such as toys, consumer electronics, small appliances, and LED lighting. It provides a safe and effective current limiting solution and ensures compliance to safety standards such as UL/CSA and ENEC. The device also provides excellent over-voltage protection and enhanced ESD protection.

The resettable fuse YQS 8120 works on the principle of a positive temperature coefficient (PTC). When the temperature increases due to overcurrent, the fuse rapidly reacts and opens up the circuit, thus preventing further damage. When the short circuit is removed, the device thermally resets back to its normal operating temperature, and the circuit can be use as normal. The device is designed to be mechanically and thermally robust, meaning it can withstand repeated thermal excursions within its current and voltage ratings.

The YQS 8120 is a reliable, cost-effective current protection solution for low power applications. It is easy to use, highly reliable and has a long life. It provides a safe and effective protection from over currents and over voltage. It also ensures that the circuit remains safe from short-circuits and power surges. This device can be easily integrated into existing circuits and offers a low-cost solution to replace traditional fuses.
