PTC resettable fuses are semiconductor devices that act like traditional fuses by providing passive thermal protection. They are also referred to as polymeric positive temperature coefficient (PPTC) devices, resettable fuses, polyfuses, or multilayer fusible resistors (MLFRs). PTC resettable fuses are ideal for overcurrent protection in circuits that need to be reset quickly and often.

The YPCJ0015T is a PTC resettable fuse designed for the protection of circuits exposed to open- or short-circuit conditions. This device monitors the load current and has an internal protection mechanism that trips the circuit when the current exceeds its rated value. When the device trips, the internal resistance increases significantly, bringing the current down to a safe level. The device automatically resets when the overload condition has been removed.

The YPCJ0015T is available in a variety of packages, such as a radial leaded version and a surface-mount style. It has an operational voltage rating of 15VDC, a rated current of 5A, and a trip current of 7.5A. The device’s thermal resistance is relatively low, which makes it suitable for use in high ambient operating temperatures. It also features a low leakage current, ensuring that the device’s resistance remains high when the device is turned off. This provides an extra layer of protection against the short-circuit currents that can occur during the startup period of some electronic systems.

The YPCJ0015T is an ideal solution for overcurrent protection in a wide range of applications, including portable electronics, communications hardware, automotive electronics, consumer electronics and power supplies. It is extremely easy to install and requires minimal maintenance, as it is able to reset itself automatically when the overload condition has been removed. Its versatility and reliability make it a popular choice for circuit protection in today’s electronics industry.

The YPCJ0015T’s working principle is based on the use of a Polymer Positive Temperature Coefficient (PPTC) device. An internal heating element is activated when a predetermined current level is exceeded. This causes a polymer-filling material to expand, which increases the device’s resistance to the current immediately. The device turns off when the current decreases to a safe level, thereby preventing damage or malfunction of the protected circuit. Once the fault condition is removed, the device automatically resets itself and is ready for further use.

The YPCJ0015T PTC resettable fuse is an efficient and reliable device for overcurrent protection in many circuits and appliances. Its easy installation and simple reset process make it an ideal solution for a wide variety of applications. Its ability to effectively respond to overload and short circuit conditions makes it an excellent choice for protecting circuits in consumer electronics and other applications.
