TRIMPOT IN MUMBAI A trimpot or trimmer potentiometer is a small potentiometer which is used for adjustment, tuning and calibration in circuits. When they are used as a variable resistance (wired as a rheostat) they are called preset resistors. Trimpots or presets are normally mounted on printed circuit boards and adjusted by using a screwdriver. The material they use as a resistive track varies, but the most common is either carbon composition or cermet. Trimpots are designed for occasional adjustment and can often achieve a high resolution when using multi-turn setting screws. When trimmer potentiometers are used as a replacement for normal potentiometers, care should be taken as their designed lifespan is often only 200 cycles. Types of Trimpots Several different versions of trimpots are available, using different mounting methods (through hole, SMD) and adjusting orientations (top, side), as well as single and multi-turn variations. Single turn Single turn trimmers/presets are very common and used where a resolution of one turn is sufficient. They are the most cost effective variable resistors available. Multi-turn For higher adjustment resolutions, multi-turn trimpots are used. The amount of turns varies between roughly 5-25, but 5, 12 or 25 turns are quite common. They are often constructed using a worm-gear (rotary track) or lead screw (linear track) mechanism to achieve the high resolution. Because of their more complex construction and manufacturing, they are more costly than single turn preset resistors. The lead screw packages can have a higher power rating because of their increased surface area. 3006P 3296W 3296P 3296X 3386P 3386W 3362P 3266W 3266X 3296Y 3296 W/B FULL RANGE AVAILABLE AT BEST PRICE, CONTACT SURAJ ELECTRONICS, MUMBAI.
