Through Hole Resistors

Through hole resistors are a type of resistor that is installed into the circuit board through a hole on the component’s surface. The metal leads are soldered to the printed circuit board to complete the connection between the component and the circuit. Through hole resistors are used to limit current in a circuit, maintain voltage, and provide a slowing effect.The H4P4K02DCA is a through hole resistor that stands for a High Resistance Series Inductor. This part is designed to help protect high-frequency digital circuits from electromagnetic interference (EMI). It works by dissipating the EMI energy as heat and then by preventing it from reaching the circuit board.The H4P4K02DCA has a resistance range of 5K9Ω to 15KΩ, a power range of 200mW to 500mW (static load), and a DCR range of 18KΩ to 22K Ω at 25°C. This resistor can operate in temperatures up to 125°C and comes with a curve rating of 104°C/W. The H4P4K02DCA is UL certified to UL94V-0 and is lead free as defined by RoHS regulations.The H4P4K02DCA is commonly used in applications with the following environments:• High voltage• High EMI• Automotive• Electronics• TelecommunicationsThe working principle of the H4P4K02DCA is that its leads carry a current that induces a voltage across the resistor. When this happens, the current dissipates through the resistor, thus limiting the flow of the current. The power rating of the H4P4K02DCA is used to determine the amount of current the resistor is able to handle safely without becoming excessively hot.In order to maintain the voltage and power, the resistor must be placed at the correct location in the circuit. This is because the resistance of the resistor depends on the number of ohms in the circuit, meaning that the resistor must be placed in such a way that its resistance is equal to the number of ohms in the surrounding circuit.In a high EMI environment, the H4P4K02DCA works by dissipating the EMI energy as heat. This dissipated energy is further reduced by reducing the inductance with a wide terminal gap. This helps reduce the amount of EMI that can travel along the circuit path. The resistor also helps reduce the circulating current, further reducing the amount of EMI.In automotive applications, the H4P4K02DCA helps protect the circuitry from voltage spikes and lowers component temperatures. The resistor can also be used to reduce noise and improve immunity to transients.In electronics applications, the H4P4K02DCA works in the same way as in an automotive application. It reduces the current and noise levels of key components, providing an improved level of protection against electrical shortages. It also helps reduce the amount of power used by the circuit as well as extended the lifetime of the resistor.In telecommunications, the H4P4K02DCA helps reduce interference from external sources. This helps keep a clear signal transmission from the device to the receiving device. The resistor is also able to reduce the amount of power consumed by the circuit, which increases the efficiency of the system.Overall, the H4P4K02DCA is a reliable and effective high-frequency digital resistor that is commonly used across a range of applications, from automotive and electronics to telecommunications. Its highly resistive nature helps protect circuits from transient voltage spikes and electromagnetic interference, while its efficient power consumption makes it a great choice for any application.
