Through Hole Resistors

Through hole resistors, also known as leaded resistors, are electrical components that are used to create precise electrical circuits with specific resistance values in the range of 1Ω to 10MΩ. They are designed to mount on board with large holes and are usually among the largest type of resistors available. Through hole resistors are commonly used for power supplies, audio equipment, military applications, industrial equipment and home entertainment systems.

H4P6K49DCA Applications

H4P6K49DCA through-hole resistors are surface mountable components that are designed to mount on board with large holes. The H4P6K49DCA resistor is a thick film resistor with a 4-digit code, which indicates its nominal resistance value of 4.6KΩ ±1%. It is used for high frequency circuits, power drivers and RF signal paths. The resistor offers excellent performance in high voltage, high power and high temperature applications with an operating temperature ranging from -55°C to +155°C.

The key features of the H4P6K49DCA resistor include a non-inductive design, low thermal EMF, low thermal noise and high power dissipation. They are generally available in a wide variety of resistance values and are often used in applications such as current-limiting circuits, low-level signal conditioning and protection of sensitive electronics.

Working Principle

The working principle of through hole resistors is simple and straightforward. When a current passes through an electrical conductor such as a wire, it encounters a voltage drop, or resistance, in the form of heat. The voltage drop in an electrical conductor occurs due to its resistance to electrical flow, and is measured in ohms, kilohms and megohms. By connecting a wire of the desired resistance value to a circuit, the current and the voltage can be adjusted, resulting in the desired resistance.

The H4P6K49DCA resistor uses a four-digit code to support its resistance range. The first two digits of this code indicate the numerical values and the other two represent the decimal point. For example, 4.6KΩ ± 1% means the resistance value is 4.6 x 103 ohms with a tolerance of 1%. This resistor is able to dissipate 0.4W of power at temperature range up to 155°C.

Conclusion

Through hole resistors are a type of resistor that is designed to mount on board with large holes for precise electrical circuits with specific resistance values. The H4P6K49DCA resistor, a thick film resistor, is one example of a through-hole resistor that is used for high frequency circuits, power drivers and RF signal paths. It works on the principle of electrical resistance whereby a voltage drop, or resistance, occurs due to a conductor\'s resistance to electrical flow.
