3323P Single-turn Metal Glass Glaze Fine-tuning Potentiometer 5k Precision Adjustable Resistor
The 3323 series single coil metal glass glaze fine adjustment potentiometer is a common type of glass glaze pre adjustment potentiometer. This potentiometer is a precision adjustable potentiometer that is typically rotated using a screwdriver, colored blue, and has three legs. It is widely used in fields such as circuit protection devices and industrial controllers.
Key Features
The 3323 Single Turn Metal Glass Glaze Pre-Regulating Potentiometer is a precision adjustable potentiometer with the following features:
1. Consists of three feet, which can be rotated all the way with a screwdriver.
2. The color is generally blue.
3. Two adjustment positions with high resistance value and low resistance value, which can be used for circuit control and protection.
4. Using metal glass glaze technology, it has high heat resistance, corrosion resistance, impact resistance and other properties.
5. It can be fine-tuned and has high adjustment accuracy.
6. Widely used in the adjustment and matching of electronic equipment.
7. With high accuracy and stability, it can ensure the normal operation of the circuit.
