Bourns 3386P 503LF Potentiomater

Bourns 3386P 503LF is a Multi-turn / Cermet / Industrial / Sealed with 5 terminal types, Tape and reel packaging obtainable. It has a Chevron seal design and Mounting {hardware} obtainable (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 unbroken present is instantly proportional to its size. The potentiometer could also be a easy machine wont to measure {the electrical} potentials (or evaluate 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. Once 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 kind of rheostat or adjustable potentiometer which can regulate, tune, and calibrate circuits. These trimmer resistors are sometimes wont to initially calibrate tools after manufacturing. Trim pots are also known as preset potentiometers used for adjustment, calibration and tuning goal 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 sorts of trimmer pots obtainable 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 optimistic 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 way of Gap. Energy Score: 500mW. Resistance Tolerance: 10%.SVHC:No SVHC ).Temperature Coefficient: 100ppm/C. Observe Resistance:20ohm.
