CT94EP503

Trimmer Potentiometers are useful for setting the value of resistors in electronic circuits. Among these devices is the CT94EP503, a two-terminal trimmer potentiometer with three leaded legs. Because of its wide range of applications, it finds use in numerous fields, from radio and television receivers to consumer electronic products. With its robust construction, it can provide reliable and accurate dial adjustments year after year.

CT94EP503 trimmer potentiometers consists of resistive track, wiper, bearing, metal and plasic parts. Resistive track is a three-terminal resistor element which is fixed in top and bottom end of the trimmer. Connecting the transistor gate and drain to outside terminals, connecting resistance is adjustable at the third terminal which is referred to as the wiper lead.

The wiper lead is spring-loaded and moves the wiper, a finger-like object, along the resistive track. The bearing of the trimmer consists of a zinc die-cast bearing and support the wiper. Metal and plastic parts provide robust construction and reliable working even in tough environmental conditions.

This trimmer potentiometer also uses thick-film technology to ensure reliable performance. Its operating temperature range is between -20°C and +100°C, making it suitable for use in industrial control and automotive applications. The insulation type of this trimmer is 3 kV, making it highly reliable in flood or other electrical storms.

The working principle of the CT94EP503 trimmer potentiometer is simple. When the wiper moves on the resistive track, the resistance between the two fixed leads changes. When the wiper is moved, the resistance changes around the wiper and a voltage is generated across it. By varying the position of the wiper, the voltage can be adjusted according to need.

CT94EP503 trimmer potentiometer is ideal for applications such as circuit tuning, audio volume control, and similar applications where exact adjustment is required. This trimmer can be used in any electronic product, from consumer electronics and automotive applications to industrial equipment, providing precise adjustment capabilities along with robust and reliable construction.
