3314J-1 Low Resistance Potentiometer
The 3314J-1 is a 4mm square single-turn sealed cermet SMD low resistance potentiometer designed for surface mount applications. Its top cross slot adjustment facilitates quick manual or automated calibration using standard tools. The device offers a resistance range from 50Ω to 2MΩ, with a focus on low resistance options (such as 100Ω, 200Ω, 500Ω), tolerance of ±10% or ±20%, and a power rating of 0.25W at 70°C. The single-turn design provides 210° electrical travel and 240° mechanical travel, making it ideal for current sensing, power management, and other applications requiring precise low-resistance adjustment. It withstands wave and reflow soldering processes.
