Introduction to H812K7BCA Through Hole Resistors

Through hole resistors are one of the most common types of resistors used in electronics. By limiting the flow of electrical current, they are able to control the amount of power that flows through an electronic component. The H812K7BCA is a through hole resistor used widely in industrial and commercial applications. It features a temperature coefficient of 0.115%, a maximum power rating of 410mW, and a range of resistance values from 1Ω to 10 megaohms. In addition, its robust design includes metal-oxide film elements, a flatband NTC inner resistor, and a curing sealant to protect against environmental conditions.
