PTC resettable fuses are highly-durable power protection devices used to protect circuit elements from physical damage and/or electrical short circuiting. PTC devices typically contain a reset switch that, when tripped, interrupts the current flow or overloads to restore a normal electrical state. By providing protection against high-current surges, PTCs can prevent system damage and ensure that the system remains operating efficiently and safely. YPCL0025N is a PTC resettable fuse designed to provide reliable protection to a system’s critical path components, such as monitors, processors, and other electronics.

YPCL0025N is an 8A PTC resettable fuse that can be used in any system or device requiring a reliable, low-impedance, current limit protection. The fuse also offers a low operating temperature range of -25°C to 85°C, making it an ideal solution for protecting sensitive electronics in extreme temperatures. The device is designed to provide reliable short-circuit protection, eliminating the need for a separate circuit breaker or surge suppressor. Additionally, YPCL0025N offers long-term protection—it can enable up to 200 cycles of reset operations before reaching its maximum temperature limit.

YPCL0025N features a working principle that can be explained as follows. When the current running through the device exceeds the rated protection level (8A in this case), the PTC fuse rapidly heats up due to the extremely small package size, creating a thermal runaway reaction. The resulting heat causes the fuse’s resistive element to open the circuit, interrupting the current flow and disconnecting the critical circuit components. Once the thermal runaway reaction is complete, the device will cool back down and the circuit will be restored. The device can also be manually reset once the fault has been cleared, ensuring that the system remains operational.

As mentioned above, YPCL0025N is designed to provide reliable and low-impedance protection to microprocessor-based systems, monitors, PLCs and other equipment that require reliable overcurrent protection. The device can also be used in medical and military applications where consistent and high-quality power protection is needed. Additionally, it can be used in automotive applications, providing overcurrent protection for ECM, A/C compressors and starter motors. The reset switch of the device can be connected to any onboard computer system, allowing it to detect any abnormal event and reset the device quickly and reliably.

Overall, YPCL0025N is an 8A PTC resettable fuse designed to offer low-impedance current limit protection and long-term protection against extreme temperatures. By providing reliable electrical safety, the device ensures that critical systems and components are protected from physical damage and/or electrical shorting. Additionally, the device can be used in a variety of automotive, medical, and military applications, providing a reliable source of power protection.
