The PTA4543-2015DPA103 is a low-profile slide potentiometer from Bourns' PTA Series, designed for professional audio and consumer electronics applications. It features a 45 mm travel distance with a linear taper, carbon element construction, and a metal lever actuator (DP style) in a single-gang configuration. The potentiometer operates with a maximum operating voltage of 150 V DC (audio mode) and 200 V DC (linear mode), with a power rating of 0.25 W (linear) or 0.125 W (audio) at 45 mm travel. Key mechanical characteristics include an operating force of 30 to 250 gf, a minimum stop strength of 5 kgf, and a sliding life of 15,000 cycles. This component is ideal for audio/TV sets, amplifiers, mixers, synthesizers, and PC applications where compact, reliable volume or tone control is required.
