The 3310C-101-203L is a 9 mm square sealed panel control potentiometer manufactured by Bourns, featuring a conductive plastic element with in-line straight terminals at 2.54 mm centers and a flatted plastic shaft. This model incorporates a 6.35 mm × 6.35 mm plastic bushing and is rated for 20 kO resistance with ±20% tolerance and ±5% independent linearity. The potentiometer delivers 100 mA at 16 VDC (resistive load), maintains 350 VDC dielectric strength, and provides 10,000 cycle switch life with a minimum detent torque of 0.5 oz-in. Its sealed construction withstands typical industrial washing processes, making it suitable for professional audio equipment, industrial control panels, and consumer electronics requiring compact, reliable panel-mounted controls.
