3329P-1-502LF – BOURNS

Overview

The Bourns 3329P-1-502LF is a high-precision cermet trimmer potentiometer designed for critical adjustment applications. Its primary function is to provide a stable and repeatable resistance setting within a 5 kΩ range, offering 0.5W power dissipation at 70°C. A key design consideration for this component is the trade-off between its excellent temperature stability (±100ppm/°C) and the potential for mechanical drift under extreme vibration or shock, necessitating robust PCB mounting and environmental sealing in demanding applications.

Key Features

• Resistance: 5 kOhms
• Power Rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature Coefficient: ±100ppm/°C
• Adjustment: 1.0 Turn Top Adjustment
• Dimensions: 0.250″ Diameter (6.35mm)

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.
