Frequently Asked Questions
Why are kinked tails important in TSM-135-03-FM-DH-A-K-TR for vibration-prone applications?
The kinked (K) tail feature in TSM-135-03-FM-DH-A-K-TR increases the contact area and mechanical grip of each SMT solder joint. For connectors with 70 positions and 0.100 inch pitch operating in vibration-prone or thermally cycling environments, kinked tails significantly reduce solder fatigue and joint failure risk.
How does the 70-position count of TSM-135-03-FM-DH-A-K-TR compare to similar SAMTEC TSM variants for board stacking?
The TSM-135-03-FM-DH-A-K-TR offers 70 positions (2 rows x 35), placing it between the 72-position TSM-136 and the 68-position TSM-134 variants. This makes it a close fit for board-stacking designs requiring a specific signal count slightly below 72 pins at the same 0.100 inch pitch.
What is the packaging format of TSM-135-03-FM-DH-A-K-TR and how does it affect procurement quantities?
TSM-135-03-FM-DH-A-K-TR ships in tape-and-reel (TR) format, which means it is ordered and consumed in reel quantities suited for SMT pick-and-place assembly. Procurement teams should confirm minimum order quantity (MOQ) with authorized SAMTEC distributors, as reel sizes for 70-position connectors typically run in multiples of 100 to 500 pieces.
