PTC resettable fuses are a type of protective device that can reset its protection function after the original overcurrent fault has been removed. They are used in a variety of applications, including medical, industrial, consumer, automotive and appliance. The PTC resettable fuse is a type of electronic circuit protection device that prevents a power supply from being damaged due to excessive current and thereby not working for prolonged periods of time. The PTC resettable fuse that we are talking about here is the CMF-SD25-10-2.

The CMF-SD25-10-2 is designed for providing over-current protection in a variety of DC power supplies, such as stand-alone DC/DC converters and AC/DC power supplies. It is able to protect the supply voltage from over-current and short circuit conditions, as well as detect any excess current in the system, preventing it from causing damage. It can also provide reverse polarity protection to the system.

This PTC resettable fuse offers a low resistance when the current is normal and a high resistance when over-current occurs. This prevents any damage to the power supply by limiting the fault current. The fuse is designed to withstand up to10A and has a rated voltage of 25V. It is available in a variety of sizes, from 15.5mm x 8.3mm to 13.5mm x 5.35mm.

The CMF-SD25-10-2 PTC resettable fuse also has a low temperature coefficient which ensures stable performance over wide temperature ranges. It has a fast reaction time and requires a short reset time, minimizing the risk of nuisance trips. This fuse has a long life expectancy and is designed to provide reliable over-current protection.

In terms of application, the CMF-SD25-10-2 PTC resettable fuse can be used in a wide variety of applications, such as power supply, medical equipment, backup power supply, DC motor control systems, electronic transformer, electronic switch, and other electrical and electronic devices. Moreover, this product is UL approved and is certified according to the EIA-595 and EN643 standards.

The working principle of the CMF-SD25-10-2 resettable fuse is fairly simple. The fuse is connected in the line between the power supply and the electrical device. When the current exceeds the fuse’s overload rating, the fuse will trip, thereby limiting the current and protecting the device from over-current damage. After the fault is removed, the fuse will reset itself and return to its normal operating condition.

To sum up, the CMF-SD25-10-2 resettable fuse is a reliable and effective overcurrent protection device that offers a long lifetime and wide application field. It is easy to install, and its simple working principle makes it the ideal choice for protecting your electronic equipment from overcurrent and short circuit damage.
