Overview
The Bourns 3314J-1-203E is a single-turn cermet trimmer potentiometer designed for precise resistance adjustment in surface-mount applications. Its primary function is to provide a variable resistance element, crucial for calibration and fine-tuning in analog circuits. A critical design consideration for this 20 kΩ, 250 mW device is its 20% tolerance; while suitable for general calibration, applications demanding sub-1% precision may necessitate a secondary, higher-resolution adjustment stage or a different component family altogether to mitigate drift and ensure long-term stability.
Key Features
- Resistance: 20 kOhms
- Power Rating: 250 mW (1/4 W)
- Tolerance: ±20%
- Temperature Coefficient: ±100 PPM/°C
- Dimensions: 4.5 mm (L) x 4.5 mm (W) x 2.55 mm (H)
- Termination Style: SMD/SMT (J-Lead)
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- Gain adjustment in operational amplifier circuits
- Offset voltage trimming in sensor interfaces
- Setting reference voltages in power supply regulation loops
- Calibration of analog signal conditioning front-ends
