Through Hole Resistors

Through hole resistors, also known as thru-hole resistors, consist of a wire wound around an insulating core, and generally have two metal leads or lugs protruding from either end for electrical connection. These are the most common type of resistors used in electronic circuits.

A popular example of a through hole resistor is the RN55E1870DR36, which is a potentiometer. This type of device consists of a resistance element, and two contacts which can adjust the resistance value.

RN55E1870DR36 Application Field and Working Principle

The RN55E1870DR36 is a type of adjustable resistor, primarily used as a voltage divider. It makes use of the resistance characteristic of the core to regulate current flow and thereby modulate voltage levels in a circuit. The device contains a series of resistive elements, which are connected in electrical series and scaled to create a precise voltage gradient.

The RN55E1870DR36 has a power rating of 18W, with a voltage rating of 360V. It features a screw-adjustment setting to allow for precise voltage control when connected to different resistors. The potentiometer is used in applications such as power supplies, inverters, amplifiers, and voltage controllers. It is ideal for applications requiring precision voltage control at low power levels.

The RN55E1870DR36 has three terminals – a wiper terminal, which is used to adjust the resistance value, and two fixed contacts which cannot be adjusted. The wiper terminal is the middle of the three, which means that the resistance value can be adjusted by turning the screw on the terminal. The two fixed contacts are used to provide the input and output of voltage and current in the circuit.

The working principle of the RN55E1870DR36 is based on the fact that the resistance between the wiper terminal and each of the fixed contacts will depend on the position of the wiper terminal. The resistance is increased or decreased depending on the position of the wiper. If the wiper is moved towards one of the fixed contacts, the resistance between the wiper and that contact will decrease, while the resistance between the wiper and the other contact will increase. The total resistance of the system can also be adjusted by placing a resistor in series with the fixed contacts.

The RN55E1870DR36 is designed to provide precise control of voltage levels in circuits, and is therefore frequently used in applications such as power control, voltage regulators, and DC-DC converters.
