SMD150F/33-2

PTC resettable fuses offer a simpler solution for overcurrent protection. The SMD150F/33-2 is a resettable fuse which offers excellent overcurrent protection with a wide temperature range and wide operating voltage that makes it suitable for many applications. It is composed of a Polymer Positive Temperature Coefficient (PPTC) and a current limiting device, eliminating any need for periodic replacement of the fuse.

Features and Benefits

The SMD150F/33-2 has a wide operating temperature range of -40°C to +125°C and is capable of withstanding high surge currents. Its low profile design and surface mount package allows easy integration into existing electronic designs. The UL V-0 rated package is highly resistant to flame and is superior to the traditional mounted fuses. This resettable fuse can be used with a wide range of applications where space is at a premium.

Working Principle

The working principle of the SMD150F/33-2 is fairly simple. When a current passes through the device, it is broken up into smaller currents that are split between both terminals. When the current reaches a threshold, the device will generate heat and swell up. This Increase in volume breaks the circuit, stopping the flow of current and protecting the circuit. The users can reset the device by removing the power supply and allowing the device to cool down. Once the device has cooled down, the circuit will resume normal operation.

Applications

The SMD150F/33-2 is designed for use in a wide range of applications, including consumer electronics, automobile, power supplies, LCD displays and medical equipment. The device can be used to protect against short circuits, overvoltage, and reverse current. The design of the resettable fuse makes it suitable for highly sensitive applications where current protection is needed. It\'s also ideal for portable consumer electronics, providing superior protection against power surges and outages. The SMD150F/33-2 is also suitable for use in automotive applications, providing overvoltage and short circuit protection.

Conclusion

The SMD150F/33-2 is an effective overcurrent protection device. Its wide operating temperature range and voltage range make it suitable for many applications where conventional mounted fuses are not suitable. It has a wide range of uses from consumer electronics to automotive applications. Its design provides superior protection against power surges and outages, making it the ideal choice for power sensitive applications. The SMD150F/33-2 is the perfect choice for users who need reliable overcurrent protection.
