Why Choose 3362P?
- Cermet Element — More stable and durable than carbon film; suitable for long-term calibration
- Sealed Construction — Dust and moisture resistant for reliable operation in PCB assemblies
- 0.5W Rating — Handles typical signal-level trimming applications safely
- 200V Max Voltage — Suitable for mains-referenced voltage divider and feedback circuits
- Standard 3-Pin Through-Hole — Fits standard PCB footprint; breadboard compatible
Typical Applications
- Op-amp offset null and gain trim (TL072, LM324, NE5532)
- NE555 oscillator frequency adjustment (R2 replacement)
- LCD contrast adjustment (10kΩ to VEE pin)
- Voltage reference fine-tuning (TL431 feedback divider)
- Sensor calibration (zero and span adjustment)
- SMPS output voltage fine-tuning
FAQ
Q: What is the difference between 3362P and 3296W trimmer?
A: 3362P is single-turn (one full rotation = full resistance range); 3296W is multi-turn (25 turns for full range). 3296W offers finer adjustment resolution; 3362P is more compact and lower cost.
Q: Can 3362P be used on a breadboard?
A: Yes — the 3-pin through-hole leads fit standard 2.54mm breadboard holes. Insert with the adjustment screw facing up for easy access.
