Through Hole Resistors

RD series resistors which include the H864R9BZA are through hole resistors. They are a board-level component that comes in axial or radial versions depending on how the pins are mounted to the board. Through hole resistors are the most common type of resistor and are generally a reliable and cost-effective solution.

Application Field

The H864R9BZA is a 400V high power resistors and is primarily used in audio amplification and power supply applications. Its ability to handle higher power loads than most through hole resistors means it can also be used in motor control systems, where it can be placed in the power factor correction circuit to suppress harmonic distortion, or power supplies, where it can be used for current limiting or short circuit protection.

The H864R9BZA is also widely used in high-voltage circuits, such as consumer and industrial circuits, and is designed to be able to handle a 400V power surge or short duration transient.

Working Principle

The H864R9BZA through hole resistors works by connecting two ends of a resistance element to two opposite sides of the same board. The resistance element is made of a material that has too high a resistance to current to be affected by a certain amount of voltage. When a current passes through the resistor, a voltage is dropped across the resistor, and this is measured as the resistance value. The lower the resistance, the higher the current that can flow through it. This value is determined by the design of the resistor circuit, and is typically measured in ohms (Ω).

The H864R9BZA is designed to have a resistance of 9 ohms, and is able to handle up to 400V of power surge or short duration transient. The resistor also has an operating temperature range of -55°C to +225°C, which makes it suitable for use in extreme environments.

In summary, the H864R9BZA through hole resistor is a generic type of board-level component and is suitable for use in high-voltage, motor control, and power supply applications. Thanks to its ability to handle high voltage transients and its wide temperature range, the H864R9BZA is an ideal choice for these types of applications.
