3299W1503 Trimmer 50K OHM 0.5W PC Pin A compact, PCBmount trimmer potentiometer designed for reliable circuit calibration and fine adjustment. The 3299W1503 provides a 50K ohm adjustable resistance with a 0.5 watt power rating and access PC pin mounting for easy inboard tuning during prototyping, manufacturing, and field service. Key benefits Accurate, onboard adjustment: access adjustment lets technicians and engineers make quick trims without removing the board. Saves time in calibration and testing: Streamlines setup and reduces rework by allowing precise resistance tuning after assembly. Reliable in small spaces: PCB pin mounting and compact form factor make it suitable for dense layouts where space is limited. Key attributes Model: 3299W1503 Resistance: 50K ohm (503) Power rating: 0.5 W Mounting: PC pin (printed circuit board) with adjustment Function: Adjustable trimmer potentiometer for fine resistance tuning How it solves common problems Eliminates the need to fixed resistors when circuit performance drifts or needs final tuning. Enables finalstage calibration after soldering to compensate for component tolerances and production variances. Provides a compact adjustment solution where panel access or larger potentiometers are impractical. Typical applications Circuit calibration and trimming in power supplies, voltage dividers, and reference circuits. Audio and instrumentation boards for final gain, offset, or balance adjustments. Prototype and production PCBs where onboard tuning and occasional field recalibration are required. Performance and compatibility notes Designed for throughhole PCB mounting using PC pins and side adjustment. Intended for lowpower trimming and calibration tasks up to the specified 0.5 W rating. Use appropriate adjustment tool and follow PCB layout guidelines for stable, repeatable settings. What you get A readytomount 3299W1503 trimmer potentiometer for precise, onboard resistance adjustment. Consistent, useraccessible tuning with a compact footprint that integrates into standard PCB assemblies.
