Through Hole Resistors

The H4243RBCA is a through hole resistor, a component small enough to be placed inside an electronic device to regulate or moderate current flow among components. Through hole resistors are often included in sensitive circuit components, such as those found in professional audio systems. Designs such as the H4243RBCA help ensure accurate signal attenuation by controlling power flow.

H4243RBCA Application Field

The H4243RBCA resistor is primarily designed for use in audio systems, including professional sound systems and theaters. It can also be used in television applications, such as cable and satellite converters, and in smaller consumer-grade electronics, such as a portable music player. The H4243RBCA is designed to be used in high-fidelity and low-impedance noise applications.

H4243RBCA Working Principle

The H4243RBCA is a type of resistor known as a voltage-derivative resistor, which uses a combination of resistance and time constant to regulate voltage. Essentially, as voltage is applied, the resistor maintains a constant resistance to control current flow, allowing for an exact voltage level to be maintained with minimal fluctuation. This approach helps to ensure signal accuracy in both the input and output stages of any associated circuitry.

The H4243RBCA is constructed with two sets of terminals, with each set connected to a unique resistor. This configuration allows for an immediate response to a voltage change, ensuring that any output voltage adjustments are applied without delay.

Cost and Availability

The H4243RBCA is a relatively inexpensive component, which makes it accessible to most consumers. It is available from most electronics stores and online suppliers, allowing users to easily incorporate it into any desired circuitry.
