D100K1K5

Adjustable power resistors are resistors that allow the resistance to be adjusted precisely even when there is an applied current. The D100K1K5 is one of the most commonly used adjustable power resistors on the market. Let\'s take a look at its specific application field and working principle.

Application field of D100K1K5 adjustable power resistors

The application field of the D100K1K5 three-terminal adjustable power resistors includes current controlled circuits, such as dimmers, analog potentiometers, TV circuit voltage stabilizers, adjustment circuit of power amplifiers, adjustment of motor speed control and electric door locks, etc. This adjustable power resistor is also utilised in electronic equipment, electric circuits and other occasions that need variable resistors.

Working principle of D100K1K5 adjustable power resistors

The way adjustable power resistors like the D100K1K5 works is quite simple. It is essentially a voltage divider, using a resistive element with adjustable resistance. A linear potentiometer element is used to facilitate full-range adjustment.

The D100K1K5 adjustable power resistor has three pins: one is to output the adjustable voltage, one is to feed the power, and the middle one is the control pin. When power is applied to the circuit, the position of the control pin is adjusted to vary the effective resistance of the adjustable power resistor. This in turn changes the output voltage to achieve a desired effect in the circuit.

The adjustable voltage range of the D100K1K5 adjustable power resistor is 0 to 14V. The change in resistance is gradual along its rotation axis. Its control type is 270 degree rotary switch. This means the intermediate range can also be adjusted, making it ideal for many applications. The shaft diameter of the adjustable power resistor is 6MM, with a flat head and a total length of 27.5MM.

Conclusion

The D100K1K5 adjustable power resistor is a three-terminal adjustable power resistor with a wide range of applications. Its linear potentiometer element enables full-range adjustment, and its 270-degree rotary switch control type facilitates precise adjustment. This makes it an ideal choice for many applications.
