100K Ohm Double Rotary Potentiometer

The WH148 100K Ohm Dual Potentiometer is a high-quality carbon film dual potentiometer, ideal for precise resistance adjustments in audio circuits and power supplies. Also known as the 100K Ohm Dual Standard Potentiometer, it features six pins (two rows of three) and a 15.6 mm round shaft for smooth rotation and accurate control. Its resistance is 100K Ohms with a ±10% tolerance, ensuring reliable and stable performance.

Key applications of this 100K Ohm Dual Potentiometer include stereo volume control, adjusting brightness or voltage in power supplies, and use in DIY electronics and laboratory projects. Its dual design allows simultaneous control of two independent channels, such as left and right audio channels, making it ideal for amplifiers, active speakers, and media devices.

The body of this dual potentiometer is made from metal and carbon film, providing precision and durability. The marking “B100K” indicates it is a linear potentiometer. It can handle up to 20 mW of power and voltages up to 500 V, making it a reliable standard choice for a wide range of electronic applications.

Overall, a dual potentiometer contains two independent variable resistors in one body. It is commonly used for adjusting two resistance values simultaneously, such as stereo volume control, saving space and allowing easier adjustment compared to using two separate potentiometers.
