C3305 Trimmer Potentiometers
Single turn glass glaze patch SMD adjustable resistors available in 1K, 5K, 10K, 20K, 50K, 100K and other resistance values.
Product Overview
C3305 Single Ring Glass Glaze Patch Pre-adjusted Potentiometer is an original integrated circuit electronic component designed for precision fine-tuning applications.
Technical Description
The 3x3 chip potentiometer consists of a resistor body and rotating system, designed for surface mounting on PCB circuit boards. When voltage is applied between the two fixed contacts, the contact point position on the resistor body is adjusted via the rotating system.
Available Resistance Values
Single coil metal glass glazed chip potentiometer C3305 offers resistance values from 100R to 1MΩ including: 100R, 200R, 300R, 500R, 1K, 2K, 3K, 5K, 10K, 20K, 30K, 50K, 100K, 200K, 500K, and 1M.
