Frequently Asked Questions
How many positions does the TSM-145-03-LM-DV-P-TR provide, and what is its contact pitch?
The TSM-145-03-LM-DV-P-TR provides 90 positions arranged in a dual-row configuration at 0.100" (2.54 mm) pitch, with 45 contacts per row. This standard pitch makes it broadly compatible with mating headers across SAMTEC's TSW and SSW series, and is one of the most widely used spacings in industrial and embedded PCB connector designs requiring 90 pins per connector site.
What does the DV designation mean in TSM-145-03-LM-DV-P-TR, and which voltage levels does it support?
The DV suffix in TSM-145-03-LM-DV-P-TR stands for dual-voltage, indicating that the connector's contacts are rated to handle multiple voltage levels within the same connector body. This is particularly useful in mixed-signal boards where 3.3 V digital signals and 5 V power rails must share a common 90-position header, reducing the number of separate connectors needed on the PCB.
Is the TSM-145-03-LM-DV-P-TR available in tape-and-reel, and how does this benefit production assembly?
Yes, the TR suffix confirms the TSM-145-03-LM-DV-P-TR is supplied in tape-and-reel format, which is compatible with standard automated SMT pick-and-place equipment. This packaging format enables high-speed placement on PCB assembly lines, reduces manual handling errors, and supports production volumes from a few hundred up to tens of thousands of units, making it suitable for both medium and high-volume manufacturing scenarios.
What is the LM contact variant in TSM-145-03-LM-DV-P-TR, and how does it differ from a standard contact?
The LM suffix denotes a low-profile metal contact variant in SAMTEC's TSM series. This contact geometry features a metallic retention mechanism that provides improved mechanical pull strength and enhanced shielding compared to standard plastic-retained contacts. For applications where vibration or repeated mating cycles are expected, such as industrial equipment operating at temperatures from -55°C to +125°C, the LM variant offers greater long-term connector reliability.
Which applications benefit most from the TSM-145-03-LM-DV-P-TR's 90-position dual-row format?
The 90-position dual-row format of the TSM-145-03-LM-DV-P-TR is especially valuable in industrial backplane systems, FPGA mezzanine boards, and high-channel-count data acquisition hardware where routing 90 signals through a single 0.100" pitch connector saves significant board space compared to multiple smaller connectors. Applications such as PLC expansion modules, industrial Ethernet switches, and test instrument front-end boards commonly use this density at 2.54 mm pitch.
