MODEL 84 1/4” Square Multiturn Surface Mount Cermet Trimming Potentiometer
The Bil technologies Model 84 series is a 1/4‑inch square, multiturn, surface‑mount cermet trimming potentiometer. It offers a wide resistance range from 10 Ω to 1 MΩ with a standard tolerance of ±10 % and an essentially infinite resolution. The device is rated for a maximum input voltage of 200 VDC (or RMS) and a maximum slider current of 100 mA, with a power rating of 0.25 W at 85 °C.
Environmental specifications include operation from –65 °C to +150 °C, a 85 °C Fluorinert® seal, and resistance to thermal shock, moisture, shock, vibration, and high‑temperature exposure. Mechanical features include clutch‑type stops and a starting torque of 3 oz‑in (0.021 N·m). The potentiometer is supplied in tube or tape‑and‑reel packaging, with pin style P‑wx and optional RoHS‑compliant codes.
