M-1303 1K

Rotary Potentiometers and Rheostats

The M-1303 1K is a type of rotary potentiometer or rheostat, usually made up of a conductive spindle that rotates in the middle of two contacts. This type of component was invented in the 19th century and has since then become a very popular and useful type of electrical device.

A rotary potentiometer is basically a variable resistor, which has three connectors; two terminals and a wiper. It is mainly used to precisely control the voltage or current in an electrical circuit. The wiper is connected to the spindle and is what can control the variable resistor. As a result, when the knob is turned, the internal resistance of the rotary potentiometer changes and the voltage or the current supplied by the circuit is adapted to the desired value.

On the other hand, a rheostat is a two terminal component that works in a similar way to rotary potentiometers, even though they are usually larger and more expensive. The main difference between a rotary potentiometer and a rheostat is that the rheostat controls the amount of current flowing through a circuit, while the rotary potentiometer controls the voltage.

The M-1303 1K rotary potentiometer is a 1 kiloohm rotary potentiometer that has a resistance range of 1000Ω. It is mainly used in circuits that require precise control of voltage or current, such as in audio frequency control systems. Some of the common applications of the M-1303 1K include volume control circuitry, adjustable power supplies, DC motor controls, and precision instruments.

The M-1303 1K has a 5-in.- square rectangular mechanical construction and a linear taper. It uses a 3 terminal pin format and operates within the temperature range of 0 to 70 degree Celsius. It has a standard wiper movement of 10mm, with a maximum rotation angle of 270°. It is a very reliable and cost-effective device, making it one of the most popularly used rotary potentiometers for different electronic applications.

In conclusion, the M-1303 1K is a type of rotary potentiometer that can be used in a wide variety of electronic applications, such as audio frequency control systems, adjustable power supplies, DC motor controls and precision instruments. It is considered to be a very reliable and cost-effective device, making it the perfect choice for any electronic situation that requires precise control of voltage or current.
