Trimmer Potentiometers

Trimmer potentiometers are precision variable resistors commonly used in electronics and electro-mechanical systems. They are especially useful where accurate, adjustable, and precise voltage or current settings are required. Trimmer potentiometers are mechanically and electrically durable, highly reliable, and require little maintenance.

3082P-1-203LF Application Field and Working Principle

The 3082P-1-203LF is a trimmer potentiometer developed by Bourns Inc. It is a single turn, conductive plastic element, precision trimmer with a resistance range of 20,000 to 200,000 Ohms. The 3082P-1-203LF is designed for use in high volume applications such as test and measurement equipment, radio and telecommunications, domestic appliances, sound systems, and all types of electronic circuits.

The 3082P-1-203LF consists of a resistive element composed of conductive plastic. The plastic element has two contact points connected to a rotating control shaft. As the rotating shaft is moved, the contact points move across the resistive plastic element, varying the resistance between the two contact points. This results in a precise setting of the resistance that can be adjusted to any desired level within the resistance range.

The 3082P-1-203LF is designed with a long-lasting conductive plastic element that resists temperature and environmental changes. The low insertion loss makes it suitable for many radio frequency and low power applications. The resistance value remains stable over life and operating temperature range. The 3082P-1-203LF has a life expectancy of 100,000 operations and is designed to offer reliable repeatability with a maximum tracking error of ±2%.
