Note: For Tape and Reel Packaging dimensions, contact 3M customer service or your preferred 3M distributor.
Dimensions in mm (Inch) with tolerance .3 for .0, .20 for .00 unless noted. Dimensions in [ ] are for reference only.
Important Notice: 3M PLCC products are tin plated on the contact wiping surface to ensure mated reliability. Tin whiskers are an inherent characteristic of tin, and mechanical stressing can drive whisker growth. It is possible for the PLCC and PLCC socket to exhibit tin whisker growth after mating. 3M follows iNEMI plating recommendations with whisker mitigating tin plating chemistry to reduce the likelihood of growth. Consider suitability for your application's lifespan, environment, mechanical stresses, humidity, and thermal cycling.
