Through-hole resistors are one of the most common and important components used in circuit design. They are simple two-terminal electrical resistors contained inside a metal tube, often ceramic and insulated from the outside environment. The H4137RBDA is a through-hole resistor particularly suited for high-temperature, high-power applications. It is designed to meet the MIL-PRF-55681C and MIL-STD-202G environmental qualification requirements.

H4137RBDA Application Field and Working Principle

A wide range of applications benefit from the use of this resistor, including hybrid and power converters, power amplifiers and audio amplifiers, heating systems and communication systems. The H4137RBDA is an excellent choice for many applications due to its ability to accurately maintain ohmic values at high temperatures, such as those found in high-power applications.

The H4137RBDA works similarly to other through-hole resistors, wherein the electrical current is sent through two terminals that are immersed in a ceramic tube containing a precise mixture of metal and ceramic powder. This mixture ensures that the resistance value remains constant even when exposed to high temperatures. The resistance is measured in ohms (Ω), with higher resistance values indicating a stronger current.

The resistor’s construction also makes it an ideal choice for high-power applications where size and weight are a factor. The ceramic tube is extremely small, yet durable, and dissipates heat quickly to prevent damage to the component. In addition, the H4137RBDA can operate at very high power levels without the need for additional cooling measures, making it an ideal choice for applications that require high performance in a compact package.

The H4137RBDA is a very reliable and efficient component, both for high-temperature and high-power applications. It is capable of maintaining very accurate resistance values over a wide range of temperatures, which makes it an ideal choice for many applications. It is also very small and lightweight, making it an excellent choice for applications that require miniaturized components or where weight is a factor.

The H4137RBDA through-hole resistor is a reliable and efficient component that can be used in a variety of high-temperature and high-power applications. Its ability to maintain consistent resistance values over a wide range of temperatures makes it an ideal choice for many high-power and high-temperature applications. Its small size and lightweight construction make it ideal for applications where size and weight are a factor.
