20K Ohm Cermet

SKU: O4HSXY70Z4
A cermet preset is a compact, PCB-mountable variable resistor with three terminals. As the adjustment is rotated, the voltage across its terminals changes accordingly. Variable resistors are used to adjust voltage levels in a circuit as required. Typically, the two outer terminals are connected to Vcc and ground (0V), while the center terminal provides a variable output voltage ranging from...

FAQ

1. What is a 20K cermet preset used for?

A 20K cermet preset is used for precise adjustment and calibration in electronic circuits, helping to control voltage or resistance levels.

2. What does “20K” signify in this preset?

“20K” means the preset has a maximum resistance of 20 kilo-ohms (20,000 ohms).

3. How is the resistance adjusted in a cermet preset?

The resistance is adjusted by turning the screw using a small screwdriver, which moves the internal wiper along the resistive track.

4. Can this preset be used as a voltage divider?

Yes, when all three terminals are used, it functions as a voltage divider to provide a variable output voltage.

5. Why is a cermet preset preferred in circuits?

Cermet presets offer better stability, higher precision, and longer lifespan, making them ideal for calibration and sensitive electronic applications.

A cermet preset is a compact, PCB-mountable variable resistor with three terminals. As the adjustment is rotated, the voltage across its terminals changes accordingly.

Variable resistors are used to adjust voltage levels in a circuit as required. Typically, the two outer terminals are connected to Vcc and ground (0V), while the center terminal provides a variable output voltage ranging from 0V to Vcc as the cermet preset is turned.

Applications:

  • Used as a voltage divider

  • Suitable for generating an adjustable output voltage
