Through Hole Resistors

A through hole resistor is a component that is designed to offer a specific electrical value that is placed in an electronic and electrical circuit for a particular task. Through hole technology is a method of creating electrical connections on circuit board assemblies by utilizing electrically conductive holes drilled into a board to connect the components, providing greater conductivity than is available through surface mount technology (SMT).

The H8953KDCA is a type of through hole resistor that combines excellent performance and reliability. Its application field includes automotive electronics, telecommunication, topology power switching, and high voltage or temperature applications.

Working Principle

The H8953KDCA Through Hole Resistor is built on a thick film hybrid substrate, which provides good dynamic resistance and ensures excellent long-term stability. It operates through the use of a resistive element with a substrate material made of metal, silicon, iron, artificial oxide, or a combination thereof. This element allows a current to pass along the surface and is designed to reduce the amount of interference from higher frequencies. The substrate material ensures that the voltage across the resistor does not exceed its safe limits, making it a very robust and reliable resistor in the long-term.

The resistive element generally consists of several layers of different materials, which are applied in a specific sequence. These layers are bonded and fired together, with the firing process usually performed at a very high temperature. This process ensures that the electrical characteristics of the resistor remain stable during its normal operating temperature range, even under extreme environmental conditions.

The H8953KDCA Through Hole Resistor also utilizes an internal thermistor, which is designed to monitor the temperature of the resistor. This thermistor is calibrated to shut off the device should the temperature exceed a certain level, thus protecting the resistor from damage and ensuring its safe operation. Furthermore, the resistor is encapsulated in a ceramic package with an epoxy material, which provides environmental protection and improves its mechanical characteristics.

In summary, the H8953KDCA Through Hole Resistor is a versatile and reliable component that can be used in a wide range of applications. It provides excellent performance and long-term stability, making it an ideal choice for high voltage or temperature applications. It also has the added benefit of being protected from extreme environmental conditions due to its ceramic-packaged design and internal thermistor.
