V481HF34

A varistor or a voltage dependent resistor (VDR or VDPR) is an electronic component that has a nonlinear, electrical stimulus-response characteristic that varies with voltage, current, and temperature. Specifically, it is a component that exhibits a significant change in resistance in response to a change in voltage. The V481HF34 is a member of TDK\'s Varistor Series. It is a type of Surface Mount Varistor, meaning that it can be mounted directly to a printed circuit board (PCB).

The V481HF34 is a 4.7mm-diameter varistor, capable of withstanding up to 400V of peak AC/DC voltage. Its unique design and high-precision construction make it an excellent choice for a variety of applications across a range of industries. It specializes in suppressing high-voltage disturbances, and is commonly used in products that require surge protection for delicate circuitry.

The V481HF34 is composed of two electrodes with metal oxide layers in between them. The metal oxide layer acts as a resistor and helps control the electrical current that passes through it. The voltage drop across the electrodes is proportional to the amount of current passing through the component. When the voltage drops to a certain level, the electrical resistance within the device changes significantly, allowing the voltage to pass through the component and causing the device to stabilize the electrical current.

The V481HF34 is a great addition to any system that needs surge protection. It is designed specifically for applications such as USB sockets, video displays, power supplies, power switches, protection circuits, and computers. It is also suitable for automotive, medical, and military applications that require dependable surge protection.

Overall, the V481HF34 is an excellent choice for surge protection. Its robust construction and precision design make it capable of withstanding a wide range of voltage spikes and disturbances. It is well-suited for use in products that require dependable surge protection for sensitive circuitry.
