H840R2BZA

Through Hole Resistors

A through hole resistor is a type of resistor which is mounted on a circuit board and secured with a through-hole mounting technique. This type of resistor is commonly used to provide impedance-matching in power electronics applications where smaller components are needed. The H840R2BZA is a through hole resistor designed specifically for power electronics applications.

H840R2BZA Application Field

The H840R2BZA through hole resistor is designed for switching power supply applications, such as high voltage DC to AC inverters, industrial motor control, lighting, and power distribution. This resistor is designed to withstand current up to 50 A and 250 V. The H840R2BZA can be used in either AC or DC applications and has high surge immunity for reliable operation.

H840R2BZA Working Principle

The H840R2BZA works by dissipating energy in the form of heat. This energy is dissipated in the form of Joule heating, which is resistance multiplied by the square of the current. The resistor\'s resistance value is determined by the size of the wire, which is wrapped around the resistor in the form of a coil. The current will cause electrons to flow through the resistor and the energy lost by the electrons is converted into heat.

The H840R2BZA resistor provides excellent electrical characteristics for power applications, with very low EMC radiation and very low inductance. This ensures a reliable operation, even in the most demanding applications. The resistor also features a wide operating temperature range, from -55°C to +155°C, so it can be used in a variety of environmental conditions.
