Through Hole Resistors

The H8169RBCA Series are precision through hole resistors specifically designed for high temperature applications with a rated voltage of 50 V to 1000 V. The H8169RBCA is a 100-ohm 0.5 ohm precision wirewound through hole resistor with a maximum temperature rating of 300 °C. The resistor is constructed with a tantalum base which is insulated with Silica. It is designed to dissipate heat better than standard through hole resistors. With this higher temperature rating, it enables them to be used in a variety of applications and environments.

Application Fields

The H8169RBCA Series is commonly used in power supplies and sensor applications where small size and high accuracy is required. It is very reliable for high-temperature applications because of its ability to operate in extremely high temperatures. The H8169RBCA series is also often used in automotive and industrial controls. It is also commonly used in high-power amplifiers.

Working Principle

The H8169RBCA Series works by creating an electrical resistance along the length of the resistor. The high-temperature rating of the resistor ensures that it can effectively dissipate any heat that is generated as current passes through it. This dissipated heat is then spread out over a wider area to prevent the resistor from overheating. The resistor also helps protect the device from voltage surges, while regulating the current. The wire used in the H8169RBCA series is an insulated tantalum material that is resistant to corrosion. The base of the resistor contains a ceramic core to provide additional support to the conductor wire.
