Trimmer Potentiometers: RJR26FW500MQ Application Field and Working Principle

Trimmer potentiometers, also known as trimpots, are adjustable variable resistors used to calibrate and adjust the performance of many different types of electronic circuits. Comparable in structure to regular rotary potentiometers, trimpots differ in that they provide adjustments that can be done manually, without the need to open the circuit or the device. This makes them indispensible tools for a variety of applications. The RJR26FW500MQ is a trimpot manufactured by Murata, and is widely used in a variety of applications. In this article, we will take a closer look at the RJR26FW500MQ, examining its application field and working principle.

Application field

The RJR26FW500MQ is suitable for use in a variety of applications, where its instant and accurate adjustment capabilities are of great value. It is commonly used in various consumer electronics, including televisions, sound systems and portable audio players. It is also widely used in automotive, communications and industrial applications. Its most typical applications include the adjustments for volume, squelch and frequency. It is used in radios and television sets, where its ability to provide quick and accurate adjustment makes it invaluable.Its ability to provide accurate and precise adjustment, free of noise or shocks, makes it suitable for many other applications. It is also used for motor speed control, where its ability to quickly adjust the speed of motors makes it an ideal choice. In general, the RJR26FW500MQ is a versatile and reliable trimpot that can be used in most applications where a precise and reliable adjustable variable resistor is needed.

Working Principle

The RJR26FW500MQ trimpot works by using a voltage-divider network. A voltage source is connected to the two fixed resistors, and the slider is connected at the mid-point, forming a voltage-divider circuit. This circuit allows the voltage to be divided into two parts, such that when the adjustable resistor (slider) is adjusted, the output voltage is changed accordingly.To make adjustments to the trimpot, the slider must be moved in the correct direction. By means of a special tool, the slider is moved clockwise or anti-clockwise, depending on the desired adjustment. By moving the slider, the resistance value of the trimpot is changed, and the voltage divider behaves differently, thus affecting the output voltage. For instance, if the slider is moved in a clockwise direction, the resistance value decreases, and the output voltage increases.

Conclusion

The RJR26FW500MQ trimpot from Murata is an excellent piece of technology that offers a range of advantages over traditional adjustable resistors. Its instant and precise adjustment capabilities, free of noise or bumps, make it a versatile and reliable trimpot, suitable for use in many different applications. Its most common application field includes volume, squelch and frequency adjustments in radios and television sets, and motor speed control. By making use of a voltage-divider network, the output voltage can be adjusted quickly and accurately.
