SMD2920P030TSA

PTC Resettable Fuses are devices used to protect against overcurrents in a variety of electronic systems. They can be used in lieu of fixed-value fuses or are sometimes integrated into circuit designs to act as heat-activated switch elements. One such PTC device is the SMD2920P030TSA. This particular fuse offers good electrical performance over a wide temperature range and has a self-resetting capability that makes it an ideal choice for many electronic applications.

SMD2920P030TSA Application Field
The SMD2920P030TSA is designed for a wide range of applications, including power supplies, DC-to-DC converters, AC/DC adapters, and consumer electronics. This PTC fuse can be used in both primary and secondary protection schemes, and it is suitable for use in automotive, telecom, medical, office automation, and industrial systems. The SMD2920P030TSA has a nominal current rating of 3A and a voltage rating of 130V, making it suitable for use in both low- and medium-voltage applications.

SMD2920P030TSA Working Principle
The working principle of the SMD2920P030TSA PTC Resettable Fuse is based on positive temperature coefficient materials. When an overcurrent passes through the PTC element, its temperature increases, which in turn increases the resistance of the element. This will eventually prevent further current passing through the element and cause it to trip. When the overload is removed and the temperature of the element decreases, the resistance will decrease as well. This will reset the element and allow current to pass through again.

The SMD2920P030TSA also provides surge protection for sensitive components. It has a maximum surge current rating of 16A and a surge voltage rating of 8V. It is designed to quickly clamp any voltage spikes or overcurrents, thus protecting the circuit from damage. The device features a UL 94V-0 rated insulation wall and a highly reliable hermetic sealing. It has an operating temperature range of -40°C to +85°C and is compliant with the RoHS Directive 2011/65/EU.

The SMD2920P030TSA PTC Resettable Fuse is an ideal choice for applications where overcurrent protection and surge protection are required. It offers an easy-to-install solution that is both reliable and cost-effective. Its self-resetting capability ensures trouble-free operation while helping to reduce maintenance costs. Its wide temperature range and highly reliable hermetic sealing make it well-suited for use in a variety of electronic systems.
