Description
The 3224J SMD Cermet Trimmer Potentiometer is a high-precision, surface-mount component designed for industrial applications. Measuring just 4 mm square, this multiturn cermet trimmer is sealed to withstand board wash processing, ensuring durability and reliability in harsh environments. Its pick-and-place centering design and flush adjustment feature facilitate easy integration into automated assembly processes.
With a standard SMD footprint, the 3224J offers a nominal resistance range from 50Ω to 2MΩ with a tolerance of 10%. It boasts a low contact resistance variation (CRV) of ≤3%R or 3Ω, making it ideal for precise adjustments. The trimmer provides effective travel of 9±2 turns and total mechanical travel of 10±2 turns, ensuring accurate tuning over its lifespan.
The 3224J is built to resist weld heat up to 250°C for 10 seconds and operates reliably within a temperature range of -55°C to +125°C. Its temperature coefficient is rated at ±250, ±100 ppm/°C, making it suitable for applications requiring high stability and precision. This robust trimmer potentiometer is perfect for use in a wide range of electronic devices where space, reliability, and precision are critical.
