Heavy-Duty Precision: RV30YN 20S 2-Watt Volume Control (B1K / B2K / B5K / B10K / B20K / B50K / B100K / B250K / B500K / 500 OHM)þ
When standard potentiometers can't handle the heat, the RV30YN 20S steps in as the industry's choice for high-power applications. This 30mm diameter carbon film potentiometer features a significant 2-Watt power rating, doubling the capacity of typical industrial pots to ensure long-term stability in high-current environments. Designed for professional-grade audio and industrial equipment, the RV30YN 20S offers the durability and precision required for mission-critical adjustments.
Key Performance Features:
-
Superior 2-Watt Power Rating: Engineered to dissipate more heat, making it perfect for power-hungry circuits where smaller pots fail.
-
Comprehensive Resistance Selection: Stocked in a full range of values: 500Ω, B1K, B2K, B5K, B10K, B20K, B50K, B100K, B250K, and B500K.

Top 3 Customer Questions & Concerns þ
-
Why use an RV30YN instead of the RV24YN?
-
The RV30YN is larger (30mm vs 24mm) and carries a 2-Watt rating compared to the 1-Watt rating of the RV24YN. If your circuit generates significant heat or carries more current, the RV30YN is the safer, more durable choice.
-
-
What does the "B" in the resistance values mean?
-
The "B" prefix indicates a Linear Taper. This means the resistance changes at a constant rate relative to the turn of the knob, providing a 1:1 adjustment feel that is easy to predict.
-
-
Can I mount this on a thin panel?
-
Yes, it includes a threaded metal collar and mounting nut. It is designed to be panel-mounted and can securely attach to anything from thin sheet metal to thick plastic chassis.
