Frequently Asked Questions
How does the polarized (P) option on TSM-121-04-TL-DH-P-TR prevent assembly errors?
The polarized lead configuration on TSM-121-04-TL-DH-P-TR includes a keying feature that mechanically prevents incorrect mating orientation across all 42 positions at 0.100 inch (2.54 mm) pitch. This reduces the risk of reversed connections during both prototype and automated SMT assembly, improving yield rates in production environments.
What manufacturing advantages does the tape-and-reel packaging offer for this 42-position connector?
Tape-and-reel (TR) packaging allows TSM-121-04-TL-DH-P-TR to be loaded directly into automated pick-and-place machines, enabling placement rates suitable for high-volume PCB production. Consistent component orientation across the 42-pin 0.100 inch pitch footprint improves solder paste alignment and reduces tombstoning defects during reflow soldering.
When should designers choose TSM-121-04-TL-DH-P-TR over a standard single-housing terminal strip?
The dual housing (DH) version provides greater board retention force compared to single-housing designs, making TSM-121-04-TL-DH-P-TR preferable in applications subject to vibration or repeated mating cycles. Industrial automation panels, embedded computing cards, and test fixtures with 42-pin 0.100 inch pitch requirements benefit most from the added mechanical security.
