1M Trimpot Potentiometer 3296W

The 3296W series is a family of multi-turn trimpot potentiometers designed for precise, stable adjustments in analog circuits. This listing is for the 1MΩ variant, ideal for fine voltage trimming, calibration, and signal conditioning in electronics components, modules, and microcontroller-based projects.

Overview 🔧

Engineered for accuracy and long-term stability, the 3296W 1MΩ is a vertical through-hole (PCB mount) trimmer with a sealed rectangular housing and a top-adjust screw. Its 10-turn mechanism enables fine control over setpoints, making it a dependable choice for lab, production, and prototyping—whether you’re building with Arduino, Raspberry Pi (via ADC modules), or other microcontrollers.

General Features 📌

• Type: Multi-turn trimpot
• Specific Value: 1MΩ (part of a family ranging from 100 Ω to 2 MΩ)
• Number of Turns: Typically 10 turns
• Mounting: Vertical through-hole (PCB mount)
• Body Style: Sealed rectangular plastic housing
• Pins: 3 pins
• Power Rating: 0.5 W (500 mW)
• Adjustment Method: Top adjustment using a screwdriver 🪛
• Series Resistance Range: 100 Ω to 2 MΩ (varies by model)
• Typical Applications: Voltage reference tuning, sensor calibration, fine analog control

Applications 🔬

• Precision voltage dividers and reference trimming
• Sensor bridge balancing and instrumentation amplifiers
• Offset/zeroing in op-amp circuits and analog filters
• Calibration in Arduino and Raspberry Pi projects (with ADC modules)
• General analog front-end tuning in electronics components and modules

Advantages ✅

• High precision due to the multi-turn mechanism
• Stable, long-lasting adjustment with sealed housing
• Higher power handling (0.5 W) compared to compact trimpots like RM065

Disadvantages ⚠️

• Larger physical size than ultra-compact trimmers
• Slightly higher cost than smaller, lower-power alternatives

Integration with Arduino & Raspberry Pi 🤖

• Use as a precise input to an ADC for measuring or setting analog levels
• Arduino: Connect the wiper to an analog input for calibration or user-adjustable control
• Raspberry Pi: Pair with an external ADC module to read analog values from the trimpot

Whether you’re an engineer optimizing analog performance or a hobbyist fine-tuning a microcontroller project, the 3296W 1MΩ multi-turn trimpot potentiometer delivers the precision and reliability you need.
