Frequently Asked Questions
How many contacts does TFM-145-22-SM-D-A-P-TR offer, and over what board span are they distributed?
TFM-145-22-SM-D-A-P-TR provides 90 contacts in a dual-row arrangement on a 0.050 inch (1.27 mm) pitch. The 45 rows span approximately 57 mm in length, enabling wide parallel data buses such as 64-bit or 80-bit interfaces within a compact PCB footprint.
Which assembly method suits TFM-145-22-SM-D-A-P-TR best for high-volume production versus field-service scenarios?
For high-volume factory production, the SM surface-mount termination on TFM-145-22-SM-D-A-P-TR integrates into standard reflow soldering at up to 260 degrees C. For field-service scenarios requiring board replacement without rework, the P press-fit option creates 90 solderless gas-tight connections that can be removed and reinserted using standard press-fit tooling.
How does TFM-145-22-SM-D-A-P-TR compare with TFM-137-22-LM-D-A-P-TR when selecting a connector for a wider data bus?
TFM-145-22-SM-D-A-P-TR provides 90 contacts versus 74 contacts on TFM-137-22-LM-D-A-P-TR, a difference of 16 additional contact positions on the same 0.050 inch pitch. Designers needing bus widths wider than 72 bits such as 80-bit or 88-bit interfaces should select TFM-145-22-SM-D-A-P-TR to avoid splitting signals across 2 smaller connectors.
