What is V441DHB34? It is a varistor, also known as a voltage-dependent resistor. It is an electronic component that limits the amount of current which can flow through an electrical circuit. It works by connecting the varistor across the supply voltage source. When a voltage spike occurs, the varistor releases the stored energy gradually, dissipating it as heat and protecting the circuit from further damage.

V441DHB34 is a Metal Oxide Varistor (MOV). It is a three-terminal component whose resistance varies depending on the applied voltage, and it is composed of an oxidized metal, which is generally zinc oxide or aluminum oxide. It is designed to protect electrical equipment from damaging overvoltages, which can be caused by power surges, switching operations, and lightning.

V441DHB34 application field includes home electronics, industrial, automotive, computers, and communication applications. It has a wide working voltage range of up to 440Vrms and a capacitance range from 200 to 900 pF. It can be used in AC and DC applications. At low voltages, the V441DHB34 remains a high impedance and is not part of the circuit, but when a voltage spike occurs above its maximum operating voltage (MOV), the oxides breakdown rapidly and the varistor releases the stored energy.

The working principle of V441DHB34 varistor is relatively simple. In an electrical circuit, it will limit or attenuate any voltage spikes that are higher than its maximum operating voltage. The varistor is connected in series with the power supply and conducts current during the transient voltage. The MOV then absorbs the current and dissipates it as heat.

V441DHB34 is a low cost, cost effective and compact design varistor. It is very reliable and can provide maximum surge protection. It can be used in a variety of applications, and can reduce overvoltage damage to electronic components in many different industrial and consumer electronics. The varistor is very durable, and can withstand multiple voltage spikes without loss of performance.
