PTC Resettable FusesPTC resettable fuses, also known as polymeric positive temperature coefficient (PPTC) devices, are self-resetting fuses that offer a unique safety protection measure for a variety of electronic devices. These types of fuses are also known as PolySwitch™, PolyFuse™, SIDACtor™ and Fusite™. In comparison to traditional fuses, PTC resettable fuses are designed to automatically reset when the element cools to a safe temperature. This unique design results in fewer circuit interruption and fewer manual reset events.The PTS120616V025 is a PTC resettable fuse with an extended temperature range that covers temperatures from -40°C to +85°C. This fuse is rated at 12V and 0.25A. The device has an operating resistance of 1 ohm and a trip current of 0.3A. The fuse has a typical hold current of 0.13A. The device is housed in a 1206 chip-size package and is ideal for low current applications such as USB, audio, computer peripherals, and consumer products. The working principle of the PTS120616V025 is essentially the same as all other PTC resettable fuses. It works by combining a positive temperature coefficient (PTC) polymer with a metal oxide varistor (MOV). When the current flowing through the device exceeds the hold current rating, the MOV element creates a voltage drop that heats up the PTC polymer element. This heating in turn increases the resistance of the element and restricts the current flow. Once the current drops below the hold current, the heating subsides and the PTC polymer element cools down and the resistance decreases resulting in the current flowing through the device. This process repeats over and over again until the device is no longer able to reset and must be replaced.Due to the unique characteristics of the PTC resettable fuse, they are ideal for use in a variety of applications. For example, they can be used to protect devices such as batteries from being overcharged or discharged, they can be used to protect circuit designs from over-heating or short-circuiting, and they can be used in automotive applications to protect circuits from overcurrent or surges. Additionally, the PTS120616V025 is ideal for use in consumer products such as electronic toys, power tools, and other devices that require a low current rating.In summary, the PTS120616V025 is a PTC resettable fuse with an extended temperature range and a low current rating. This fuse is designed to protect circuits from over-current, over-charging, over-heating and short-circuiting. It is ideal for use in a variety of applications and consumer products. The device works by combining a PTC polymer element with an MOV element and is capable of resetting on its own until it can no longer reset.
