Through Hole Resistors are ubiquitous in a wide range of electrical and electronic engineering applications. One of the most common applications for THRs are in DC current limiting, voltage switching and safety applications. The H421KBDA is a highly configurable product designed to safely and accurately limit DC current with adjustable set points and over-current protection. The device is an efficient design that can be used for a variety of applications from automotive to industrial and consumer components.

The H421KBDA uses a unique, self-contained, silicon-on-oxygen (SOX) technology to provide reliable current limiting with adjustable step-down power switching across a wide voltage range. The device is based on the principle of using a resistor to limit the current when the load reaches its peak current draw. The SOX technology allows precise adjustment of the current limit. It also provides a diminutive form factor; the device is only 4.2mm x 2.2mm.

The H421KBDA is a two-terminal resistive current limiter. It is integrated with a field effect transistor (FET) to control the current flow and protect the linear FET protection circuits and provide enhanced overload and transient protection. The adjustable current limiter prevents both circuit and component damage due to over-current conditions during transient events. To provide users with maximum flexibility, the device has an adjustable set point for current limiting.

The H421KBDA also features an adjustable over-current protection circuit. This feature protects circuits and components from excessive current caused by power surges or current spikes. An over-current protection circuit can be used to prevent circuits and components from being damaged by the surge or spike. The device also includes an over-temperature protection feature which can protect the circuit and component from thermal damage due to excessive temperatures.

The H421KBDA can be used for many other applications, such as motor control, switch control, and battery management systems. It is also a great option for devices that require an adjustable current limiter for load balancing or current reduction. The adjustable current limit can be set to the point that the device requires for protection, while the over-current protection circuit ensures maximum safety and reliability.

The H421KBDA is a reliable, cost-effective current limiter. Its compact size and wide operating range make it ideal for many high-reliability applications. The device is also low-noise and low-power, making it suitable for low-power consumption applications. The adjustable current limit and over-current protection circuits protect critical components and circuits while having an additional benefit of increasing system efficiency and reliability.
