Trimmer Potentiometers

Trimmer Potentiometers, such as 3299X-1-103LF, are a type of Voltage controlled resistor (VCR) and adjust the output of a circuit by changing the voltage applied to the VCR. VCRs are commonly used in electronic systems, from low voltage to high voltage circuits, for wide variations of resistance values. The 3299X-1-103LF is specifically designed as a trimmer potentiometer, and its application field and working principle can be broken down into three main segments: Design, features, and performance.

Design

The 3299X-1-103LF is constructed with a 10,000-ohm (KΩ) resistance value and rated for 10 watts. In order to resist the heat generated from this wattage, a porcelain body is used. Along with the black and red color coded terminals that allow the user to connect two different sets of leads, the VCR is built with a 3-position actuating feature which is convenient in structuring the resistance settings.

Features

The 3299X-1-103LF offers several features for comfortable and adjustable use. Since the VCR is rated at 10 watts, it offers high power capabilities; this allows it to be used in application fields that require over-current capabilities. Additionally, the VCR provides an excellent temperature stability rating of ±0.5°C, making it safe to use in high temperature applications.

Performance

The 3299X-1-103LF is designed to resist harsh electrical surges. It has a maximum voltage rating of 250VAC/12VDC, and a maximum inrush current rating of 600VAC/75V. Additionally, it has an operating temperature of -40°C to +85°C over the entire actuation arc – making it suitable for use even in extreme conditions. On all levels, it is designed for performance and dependability.

Summary

In conclusion, the 3299X-1-103LF is a trimmer potentiometer with a rated resistance value of 10,000-ohm, and a rated power of 10 watts. It has a porcelain body composition and two color coded terminals for easy connection. High power capabilities, excellent temperature stability, and a maximum voltage rating of 250VAC/12VDC make this VCR suitable for a multitude of different applications. On all levels, it is designed for performance and dependability.
