72PXR200LF

Trimmer potentiometers are special types of potentiometers that are specifically designed for precision adjustment. They range from single through to multi-turn, and from low power through to high power applications. They are used in a wide variety of applications, from consumer products to industrial control systems.

The 72PXR200LF is a trimmer potentiometer from BC Components designed for use in a variety of applications, including audio, radio, telecommunication and medical devices. It is a bi-directional, single-turn potentiometer, meaning the resistance can be adjusted in either clockwise or anti-clockwise direction within a range of 200Ω.

Application Field of 72PXR200LF

The 72PXR200LF is suitable for a wide range of applications, such as control circuits, power circuit voltage and current adjustments, audio volume control and balance, input matching circuit impedance adjustment, and circuit frequency tuning. It is suitable for use in a wide range of industrial and consumer electronics. It is compatible with a variety of soldering processes, including the reflow, wave and selective soldering processes.

The physical form of the 72PXR200LF is designed for surface mount applications, with a package body size of 3.2 x 2.7 x 2.5mm, and is compliant with the RoHS (Europe\'s Restriction of Hazardous Substances) directive. The potentiometer has a resistance range of 0 to 200Ω with a 5Ω stepping. The 72PXR200LF has an operating temperature range between -30°C and +110°C.

Working Principle of 72PXR200LF

The potentiometer consists of two main parts – a base terminal, and a terminal connected to a resistive element. The base terminal is connected to the circuit\'s ground or power source, and the second terminal is connected to a variable resistive element. This resistive element is adjusted by rotating a knob attached to the base terminal. Rotation of the knob causes the resistance to the base terminal to change, depending on the direction of rotation.

When the knob is rotated clockwise, the resistance increases, and when it is rotated anti-clockwise, the resistance decreases. This variation in resistance can be used to control the circuit, typically by adjusting the current or voltage in the circuit. The 72PXR200LF can also provide fine-tuning control for a range of applications, such as input matching circuit impedance adjustment, and circuit frequency tuning.

The 72PXR200LF has a number of features which make it an ideal choice for precision adjustment. It has a long life of up to 8000 cycles, and a low wiper resistance of 30mΩ. It also has a low thermal EMF, and excellent linearity, and it is RoHS compliant.
