Adjustable Volume Control Potentiometers

The 3386P series potentiometers are high-precision, single-turn, PCB-mounted adjustable resistors designed for fine-tuning and calibration in a wide range of electronic circuits. Featuring a compact, durable, and sealed design, the 3386P is ideal for industrial, automotive, communications, and consumer electronics applications where reliable adjustment and space-saving are important.

The 3386P model specifically offers vertical mounting with a top-adjustable slot accessible by a screwdriver, making it easy to adjust after PCB installation. Its rugged construction ensures long-term stability, excellent mechanical life, and resistance to environmental contaminants like dust, flux, and solvents.

Features:

Single-turn adjustment for easy and precise calibration.
Top-slotted adjustment for convenient tuning after assembly.
Sealed housing to protect against dust, moisture, and flux contamination.
PCB through-hole mount for secure and reliable connections.
Wide resistance range options from 100Ω to 2MΩ.
High reliability with excellent rotational life and resistance stability.
Compact size ideal for dense PCB layouts.
