Trimmer Potentiometers refer to a variety of adjustable resistors used to adjust the electrical circuit characteristics. The 67WR200LF is a trimmer potentiometer manufactured by Yageo which is a Taiwanese manufacturer headquartered in Taipei, Taiwan. It is often used as a variable gain amplifier, pitch control or other adjustable gain/attenuation and offset control applications.

The 67WR200LF features an overall package size of 12.8mm in diameter and a maximum wiper arm to termination clearances up to 1.0mm. It is a two-terminal variable resistor that consists of a fixed resistive element and a moving contact (termed the wiper) that adjusts the resistance of the part. This trimmer potentiometer is a sealed encased component and provides a high degree of environmental and EMI shielding for noise-sensitive applications.

The 67WR200LF is a rotary type of trimmer potentiometer, and is also referred to as an "endless" trimmer, either "thumbwheel" or "knob adjustable rotary" potentiometer. The resistance value is set by slowly rotating the spindle of the device which, in turn, causes the wiper to move across the resistive element to adjust the resistance. This trimmer offers a rotational life of 10,000 cycles and a linear rotational resistance up to 200Ω.

The 67WR200LF is a single turn trimmer, meaning the resistance value can be adjusted by rotating the device spindle through a full 360° turn. The rotation of the spindle adjusts the resistance between the two terminals of the device. The device is often used as a voltage divider, when an adjustable voltage is desired in an AC or DC circuit.

In audio applications, the 67WR200LF can be used to adjust the gain applied to an input signal, either by amplifying a weaker signal or by attenuating a louder signal. In a DC circuit, when the wiper is connected to ground, the 67WR200LF is sometimes referred to as an offset control, as the device can adjust the base voltage or offset for a DC circuit.

Since the 67WR200LF is a sealed encased component, it is suitable for numerous industrial and commercial application where dust, moisture, and/or corrosive environment are present. Typical industrial applications include medical instrument control, automotive, and robot control.

In conclusion, 67WR200LF is an adjustable trimmer potentiometer used to adjust electrical circuit characteristics. It has a compact design, a wide resistance value range, and is shielded from environmental elements, making it suitable in many applications.
