Introduction

Trimmer Potentiometers are electronic components used to adjust the electrical properties of an electronic circuit, such as voltage, current, or frequency. Usually used in maintenance and overhaul. The 67PR100KLFTB Trimmer Potentiometer are the most widely used types of trimmers for general applications, widely used in amplifiers, medical equipment, mixers, industrial controls, communications, measurement equipment and other related fields. They are constructed with a voltage rating of up to 100V and a resistance range up to 100KΩ.

Application Field

The 67PR100KLFTB Trimmer Potentiometer is a versatile component that can be used for a variety of applications, including:1. Adjustment for AC or DC amplifiers such as audio amplifiers, radio receivers, power amplifiers, and other high voltage/current products. 2. Automatic component adjustments on medical equipment, such as x-ray machines, medical scales, heart rate monitors and other similar products.3. Potentiometers for electronic test instruments, such as measuring meters, oscilloscopes, bridge networks and other similar products.4. Signal adjustment in several types of digital electronic circuits, such as video monitors, signal analyzers, and digital microphones, etc.5. Used in settings and adjustments of frequency modulation in both industrial and consumer products.6. Adjustment for the current and voltage of stepper motor devices.

Working Principle

The 67PR100KLFTB Trimmer Potentiometer is a three terminal resistor with a resistive element, connection terminals and an actuating mechanism. The resistive element of this trimmer is a flat film composed of carbon, metal or ceramic that passes double between the two contact terminals. The actuating mechanism consists of a plucker that presses the resistive element between the contact terminals. This pressure also facilitates the contact between the resistive element and both terminals, providing an adjustment range of about ±10% to ±30%. The adjustment of the trimmer is done fairly easily by turning the knob of the actuating mechanism. This simple process causes a variation of the resistance of the resistive element, and with it the value of the electrical characteristic that is being adjusted. It should be noted that the knob can be turned both clockwise and counterclockwise.

Conclusion

The 67PR100KLFTB Trimmer Potentiometer is one of the most popular and widely used trimmers in many fields and products, primarily due to its high reliability, versatility, and easy setup. It has a wide range of applications, adjustable range of up to ±30%, and a robust construction that allows it to withstand voltage levels up to 100V and resistance levels up to 100KΩ. Its working principle is relatively simple, whereby an actuating mechanism applies pressure to a flat resistive element, allowing for easy adjustment of the trimmer\'s values.
