Trimmer Potentiometers are essential components in many electronic products and systems. They are used to precisely adjust resistance values in order to fine-tune and optimize performance. Y4069100R000J9L is a trimmer potentiometer manufactured by Murata. It is a single-turn, linear taper device with an operating torque range of 20 – 30 mNm. This article will examine Y4069100R000J9L\'s application field and working principle.

Application Field

Y4069100R000J9L is designed for a wide range of applications including audio volume controls, ultrasonic transducers, scanning electron microscopes, servo motor control systems, and many more. It is particularly suitable for sensitive applications where high linearity is preferred. It is also ideal for general-purpose use with an operating temperature range -10ºC to +60ºC.

The device offers a resistance range of 10 ohms to 1Mohm in one-turn versions. It is equipped with a M4 x 0.7 threading enabling secure panel mounting. It is rated for an impressive power rating of 0.1W, offering a packing density of 14mm2. All these features, coupled with an impressive pulse response of 10kHz make it suitable for many boutique and high-end audio applications.

Working Principle

Y4069100R000J9L is a trimmer potentiometer that works on the principle of Resistive Temperature Coefficient (RTC). This is a resistor type that can be easily adjusted with a tool such as a screwdriver to change its value. Inside the device, there are two electrodes connected to the terminals, where the voltage is applied. When the potentiometer is rotated, a small electric current is sent through the device, causing the resistance to change as the electrodes move closer or further away. This ability makes the potentiometer an ideal instrument for accurately adjusting and calibrating the resistance values of a system.

This trimmer potentiometer offers an insulation resistance of 9 GOhms at 500V AC. This ensures that the device is capable of operating reliably even in harsh environments, providing excellent insulation for a long period of time. It is characterized by a linearity of +/- 0.2% - mainly depending on the operating torque range - for resistance values at the end of the adjustment range.

Conclusion

Y4069100R000J9L is a useful trimmer potentiometer manufactured by Murata. It offers a wide range of applications in various industries, providing a linearity of +/- 0.2% for values at the end of the adjustment range. Working on the principle of RTC, this trimmer potentiometer offers an insulation resistance of 9 GOhms at 500V AC, enabling it to be used in harsh environments, while providing excellent insulation. All these features coupled with its impressive pulse response of 10kHz make it one of the best choices for high-end audio applications.
