72PMR500LFTB

Introduction

Trimmer Potentiometers are a type of adjustable resistors used in electronic circuits to create a manually adjustable voltage divider. The most common ingredient in an electronic circuit, the trimmer pot is typically used in feedback loops, level-shifting, impedance matching, and voltage regulation circuits. The preferred type of trimmer for use in electronic circuits is the 3386 Series Trimmer Potentiometer with a 72PMR500LFTB designation.

Application Field and Working Principle

The 72PMR500LFTB is a precision trimmer potentiometer that is designed with a linear relationship between resistance and the angle of rotation in order to maintain accuracy. It is typically used to adjust the gain of an amplifier or other circuit elements. The 72PMR500LFTB uses a conductive plastic element with metal film resistive element that is highly corrosion resistant for stable performance and long-term operation. The 72PMR500LFTB is designed to have a minimum resistance of .5 Ohm, while the maximum resistance is 50 KOhm. The adjustment range of the 72PMR500LFTB is from 0 to 500 Ohms. It comes in a rugged, IP67 dustproof and waterproof housing for outdoor operation.

The 72PMR500LFTB is used in many different circuits and applications. It is often used in audio applications for setting gain levels or in power supplies to adjust the output voltage. It is also used in digital cameras, consumer electronics, medical devices, and automotive systems. The 72PMR500LFTB has a wide range of applications where an adjustable voltage divider is necessary. The adjustment range of the 72PMR500LFTB makes it ideal for precision adjustments in various circuits.

The working principle of the 72PMR500LFTB is similar to that of other trimmer pots. The element inside the 72PMR500LFTB is made of a resistive material with a sliding contact, which is connected to the external wiper arm. Turning the knob or shaft of the 72PMR500LFTB increases or decrease the resistance of the element. The adjustment range of the 72PMR500LFTB is from 0 to 500 Ohms. The element\'s resistive material gives a linear relationship between resistance and the angle of rotation.
