Potentiometer

Bourns PTV09A-4225F-B203 is a through-hole rotary potentiometer in the PTV09A series, a three-terminal passive variable resistor with a shaft-actuated wiper for manual level, gain, or bias adjustment. It exposes three pins: END1 and END3 as the resistive element end terminals and WIPER as the moving contact, with adjacent pins spaced approximately 2.5 mm apart. The body measures 13.6 x 13.45 x 25.01 mm and includes two mechanical mounting-hole pads that carry no electrical net. Resistance value, taper, power rating, and voltage limits are not specified here and must be taken from the Bourns datasheet.
