PTCCL09H541DTE

PTC Resettable Fuses are overcurrent and overtemperature protective devices designed to replace traditional fuse-based protection. PTC Resettable Fuses, sometimes referred to as poly switches, offer the benefits of improved reliability, greater design flexibility and longer life-span when compared to traditional mechanical fuses. The PTCCL09H541DTE PTC Resettable Fuse is one such device and is suitable for use in a wide range of applications.

Applications of PTCCL09H541DTE PTC Resettable Fuse

The PTCCL09H541DTE PTC Resettable Fuse is a low resistance, single shot type PTC Resettable Fuse. The device has a wide variety of applications such as overcurrent and overtemperature protection for consumer electronics and non-automotive automotive applications. It can be used in wireless chargers, laptops, LED lighting applications, automotive USB charging ports, and battery-equipped consumer products such as wearable devices, hearing aid accessories, and cell phones. This device can also be used as a general-purpose resettable overcurrent and overtemperature protection for other consumer electronics.

Working Principle of PTCCL09H541DTE PTC Resettable Fuse

The PTCCL09H541DTE PTC Resettable Fuse uses a Thermistor to achieve its functional behavior. Thermistors are semiconductor materials that exhibit non-linear changes in electrical resistance when exposed to changes in temperature. A certain amount of energy is required to increase the temperature of a thermistor enough to cause the necessary change in resistance. This energy is referred to as the trip energy. When the trip energy is exceeded, the PTCCL09H541DTE PTC Resettable Fuse will trip and become non-conductive. The device will remain non-conductive until the circuit is opened and allowed to cool. Once the device has cooled, the device will return to its conductive state and the circuit will be re-enabled.

The PTCCL09H541DTE PTC Resettable Fuse is designed to protect delicate circuits from damage due to overcurrent or overtemperature conditions. The device can be used to provide overcurrent protection in a wide variety of applications, as well as overtemperature protection. The device’s unique features make it an ideal choice for applications that require reliable and consistent protection.

Conclusion

The PTCCL09H541DTE PTC Resettable Fuse is a versatile device suitable for a wide variety of applications. It can be used to provide reliable overcurrent and overtemperature protection in wireless chargers, laptops, LED lighting applications, automotive USB charging ports, and battery-equipped consumer products. The working principle of the device is based on the use of a Thermistor which is able to detect changes in temperature and operate accordingly. This device is ideal for applications that require reliable protection from overcurrent and overtemperature conditions.
