C3305 Metal Glass Glazed 3x3mm Trimmer Potentiometer with 100Ω-1MΩ Range and 0.1W Power Rating
The C3305 is a compact 3x3mm SMD adjustable resistor featuring metal glass glazed construction for superior performance in electronic circuits. This single-turn trimmer potentiometer offers precise resistance adjustment for fine-tuning applications.
This 3x3 chip potentiometer consists of a resistor body and rotating system, designed for surface mounting on PCB circuits. When voltage is applied between the two fixed contacts, the contact point position on the resistor body can be precisely adjusted through rotation.
Single coil metal glass glazed chip potentiometer C3305 offers comprehensive resistance range:
- 100Ω, 200Ω, 300Ω, 500Ω
- 1K, 2K, 3K, 5K, 10K, 20K, 30K, 50K
