Through Hole Resistors

A through hole resistor is an electronic component that comes with an insulated wire or leads that are passed through a hole on a printed circuit board (PCB). Through hole resistors are also known as leaded resistors and are typically used in high power or high frequency applications. They are capable of dissipating large amounts of heat and are the most common type of resistors used in electronic products. To ensure the desired resistance value is maintained, the leads are usually soldered to the holes on the board.

H426K1BYA Application Field and Working Principle

The H426K1BYA is a through hole resistor assembly manufactured by Panjit and is designed specifically for high-power applications. It features a metal oxide film resistor with two axial leads which are soldered to the printed circuit board. The H426K1BYA is typically used in power supplies, UPSs, and voltage regulators, and can handle up to 6A current. The resistor is also RoHS compliant and meets the requirements of UL 94V-0 flammability standard.

The working principle of the H426K1BYA is based on the Ohm’s law, which states that the current passing through a resistor is proportional to the voltage applied across its two terminals. It is constructed from a metal film composite which is deposited onto an insulating substrate. This substrate material is often a ceramic material or sometimes a polyimide material. When a voltage is applied across the lead terminals, the metal film composition acts as a resistor and limits the amount of current that can flow through the device.

The resistance value of the H426K1BYA is accurately determined by controlling the thickness and length of the metal film composition. This ensures that the exact current limiting value is achieved and that the resistor can handle increased power without any issue. In order to ensure that the element is kept safe, the resistor is coated with an insulating resin which can tolerate high temperatures.

The H426K1BYA is a versatile through hole resistor and is suitable for a wide range of electronic applications. It offers high power capabilities and provides reliable performance in high frequency circuits. Due to its accurate resistance value and reliable performance, it is the perfect choice for applications where precision and durability are essential.
