Bourns 3386P 203LF Potentiomater

Bourns 3386P 203LF is a Multi-turn / Cermet / Industrial / Sealed with 5 terminal types, Tape and reel packaging accessible. It has a Chevron seal design and Mounting {hardware} accessible (H-117P) with RoHS compliant. The precept of a potentiometer is that the potential dropped throughout a phase of a wire of uniform cross-section carrying a seamless present is straight proportional to its size. The potentiometer could also be a easy gadget wont to measure {the electrical} potentials (or examine the e.m.f of a cell).

A trimpot or trimmer potentiometer could also be a small potentiometer which is employed for adjustment, tuning and calibration in circuits. After they’re used as a variable resistance (wired as a rheostat) they’re referred to as preset resistors. A trimmer potentiometer, additionally known as a trim pot, could also be a type of rheostat or adjustable potentiometer which can modify, tune, and calibrate circuits. These trimmer resistors are sometimes wont to initially calibrate gear after manufacturing. Trim pots are also known as preset potentiometers used for adjustment, calibration and tuning objective in circuits. They’re simply mountable on PCB boards and adjusted by a screwdriver. The resistive observe is made up of carbon composition or cermet. When changing with regular potentiometers, bear in mind their lifetime is not goodbye. There are differing forms of trimmer pots accessible in market like by gap, smd, single and multi-turn variation.

To make use of a Trimpot potentiometer merely join the CCW and CW terminal with constructive provide and floor terminal respectively and get variable output voltage from the wiper terminal. To alter the output voltage rotate the screw on the best of the Trim pot. This screw rotate the wiper positioned contained in the pot, which varies the resistance. It’s utilized in Voltage and Present Management Circuits, Used as quantity management knobs in radios, Tuning or controlling circuits, Analog enter management knobs. No. of Turns:25.Potentiometer Mounting: By Gap. Energy Ranking: 500mW. Resistance Tolerance: 10%.SVHC:No SVHC ).Temperature Coefficient: 100ppm/C. Monitor Resistance:20ohm.
