Trimmer Potentiometers

Trimmer Potentiometers, also known as trimpots, are adjustable resistors which are used in applications like analog circuitry and digital circuitry, for the purpose of splitting and fine tuning the power output to a desired level. With the help of the trimponent, we can make very precise adjustments to the device’s output.

3303W-3-202E Application Field and Working Principle

The 3303W-3-202E is part of the Series 3303W Trimmer Potentiometer from Bourns. This particular trimpot is designed for use in various electronic and automotive control systems. It features a single turn design with a top adjustment screw design for precise regulation. A single turn, adjustable resistance is created when the adjustment screw is applied and connected to a strain gage. This allows the user to tune the output power to a more specific level with increased accuracy.

The 3303W-3-202E stands out from other trimmer potentiometers with its low profile and tall 16mm design. It is designed to fit in tight spaces and to make it easier to access for fine-tuning. The device features a high-reliability capacitive element with a maximum rated power rating of 200W, which makes it well-suited for applications like automotive electronic circuitry. It also has a low distortion rating, making it superior to traditional ceramic trimpots in terms of accuracy.

The 3303W-3-202E’s maximum resistance value of 10K ohms is suitable for a range of applications that require delicate adjustments to power output. The device’s resistance value is determined by the adjustment screw. When the screw is turned clockwise, the resistance value increases and when it is turned counterclockwise, the resistance value decreases. The 3303W-3-202E is also equipped with three separate adjustment ranges, so the user can easily adjust the resistance value between 10K ohms and 10K ohms.

Other features of the 3303W-3-202E include a 0.2W power rating and a 30mΩ minimum resistance. The device also features a voltage rating of 30V maximum, a temperature range of -55°C to +150°C, and a dielectric strength of 1500V. As mentioned above, the 3303W-3-202E is a single turn design trimpot, so the user can make precise adjustments to the output power with less difficulty.

The 3303W-3-202E is designed for use in harsh environments with its high-reliability capacitive element and wide operating temperature range. Additionally, the device features a Teflon sleeve for additional protection and a two-piece construction with stainless steel compression springs for secure mounting. With the help of the 3303W-3-202E, users can make instantaneous and precise adjustments to the output power of their circuitry in various applications.
