1 Packaged on 13" recyclable reels. Tape width is 24mm and 16mm.
Pitch is 16mm and 12mm. Reels conform to EIA-481.
2 (1) See PEM® Technical Support section of our website for related plating standards and specifications.
(2) Optimal solderability life noted on package.
(3) The tin deposit on SMTSK standoffs meet the requirements of ASTM B545, Class A and although the copper and nickel barrier layers used under the tin do not strictly comply with ASTM B545 thickness requirements they have proven effective at preventing zinc migration and providing the specified solderable shelf life.
