Through Hole Resistors

Through hole resistors, also known as THRs or plug-in resistors, are resistors which use drilled holes through the body of the resistor. The term "through hole" is used to refer to electronic components which need to be mounted through a hole in the board, rather than those which are mounted to the top or sides of the board.

H4P2K05DZA Application Field and Working Principle

The H4P2K05DZA is a through hole resistor with the widest application field. It is a plug-in resistor, which enables it to be easily inserted and removed. This type of resistor is suitable for applications requiring high voltage, low power, and long life. The H4P2K05DZA resistor features a low resistance value range between 20 ppm and 120 ppm. It also has a very low thermal coefficient, making it suitable for applications which require a stable temperature change.

The working principle of the H4P2K05DZA resistor is based on the so-called "ohmic contact" effect. The hole in the body of the resistor transfers the current or voltage to an insulated conductive material. The ohmic contact effect makes the resistor almost immediately switch to its intended position upon applying the voltage or current. The resistor is then ready to dissipate the heat generated by the current or voltage. This means that the resistor can maintain its low profile even in very high voltage applications.

The H4P2K05DZA resistor is an ideal choice for high voltage, low power, and long life applications due to its low resistance range and thermal coefficient. Its plug-in style makes it convenient for applications where frequent replacement is necessary and its ohmic contact effect ensures quick switching and heatsinking. The H4P2K05DZA also features an optimized temperature range, making it suitable for all types of applications.
