Overview
The Bourns 3386F-1-203TLF is a sealed cermet trimmer potentiometer designed for precise resistance adjustment in sensitive electronic circuits. Its primary function is to provide a variable resistance element with a 20 kΩ nominal value and a robust 0.5W power rating, crucial for maintaining stable bias points or calibration settings. A key design consideration for applications utilizing this component is the inherent trade-off between adjustment resolution and long-term stability; while the single-turn mechanism offers fine-tuning, environmental factors like humidity can impact cermet element drift over extended operational periods, necessitating careful enclosure design.
Key Features
- Resistance: 20 kOhms
- Power Rating: 0.5W (1/2W)
- Tolerance: ±10%
- Temperature Coefficient: ±100ppm/°C
- Adjustment: 1.0 Turn, Top Finger
- Dimensions: 9.53mm x 9.53mm (0.375″ x 0.375″) Square
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.
- Calibration of sensor signal conditioning circuits
- Setting gain and offset in analog instrumentation
- Fine-tuning of voltage-controlled oscillators (VCOs)
- Establishing reference voltages in power supply regulation loops
