The 3310C-101-502L is a 9 mm square sealed panel control potentiometer manufactured by Bourns, featuring a conductive plastic element with a flatted shaft and in-line straight terminals at 2.54 mm centers. This model is configured with a 6.35 mm × 6.35 mm plastic bushing and offers a resistance value of 5,000 ohms with ±20% tolerance and ±5% independent linearity. The potentiometer delivers an effective electrical angle of 270° ±15°, a contact resistance of 2 ohms maximum, and a power rating of 100 mA at 16 VDC, with a dielectric strength of 350 VDC and switch life of 10,000 cycles. The compact sealed design withstands typical industrial washing processes and is RoHS compliant, making it suitable for professional audio equipment, industrial control panels, and consumer electronics requiring reliable volume or parameter adjustment in harsh environments.
