What are the key features of TSM-118-05-LM-SH-P-TR?

  • 18-position dual-row layout at 0.100" (2.54 mm) pitch delivers compact high-density signal routing on SMT boards
  • Shielded construction attenuates EMI for signal integrity in noise-sensitive PCB environments
  • LM tail style and P polarization key prevent mismating and ensure correct connector orientation during assembly
  • Tape-and-reel (TR) packaging enables automated pick-and-place at high production volumes

What is TSM-118-05-LM-SH-P-TR used for?

The TSM-118-05-LM-SH-P-TR is suitable for embedded computing, industrial control boards, and instrumentation designs where 18-position dual-row SMT connectivity is needed with EMI shielding at 0.100" pitch. The polarization key prevents assembly errors on high-mix production lines, making it well-suited for consumer electronics and telecommunications hardware. Its tape-and-reel format supports volume SMT manufacturing with minimal manual handling.

Frequently Asked Questions

How many contact positions does TSM-118-05-LM-SH-P-TR provide and how are they arranged?

The TSM-118-05-LM-SH-P-TR provides 18 positions arranged in a dual-row configuration at a 0.100" (2.54 mm) pitch, giving 9 positions per row. This dual-row layout doubles pin density compared to a single-row strip of the same footprint length, making it effective for embedded systems, backplane daughter cards, and compact sensor interface boards.

How does the shielding on TSM-118-05-LM-SH-P-TR reduce interference in high-speed designs?

The integral shield on TSM-118-05-LM-SH-P-TR reduces electromagnetic interference by providing a grounded conductive enclosure around the signal contacts, attenuating radiated emissions and crosstalk at signal frequencies above 100 MHz. This shielding is especially valuable in FPGA development boards, wireless module interface headers, and data acquisition systems operating near switching power supplies or RF sources.

What role does the P polarization key play during board assembly of TSM-118-05-LM-SH-P-TR?

The P polarization key on TSM-118-05-LM-SH-P-TR provides a mechanical feature that prevents incorrect mating orientation, eliminating pin 1 reversal errors during assembly. This is critical on dual-row 18-pin connectors where a reversed mating connector could apply reversed signals to 18 circuits simultaneously, potentially damaging ICs. The key reduces rework costs on high-volume SMT lines handling mixed connector types.

When should a designer choose TSM-118-05-LM-SH-P-TR over a non-shielded 18-position alternative?

A designer should choose TSM-118-05-LM-SH-P-TR over a non-shielded alternative when signal lines operate above 50 MHz, when the PCB is near switching regulators generating 50 kHz to 2 MHz noise, or when regulatory compliance with FCC Class B or CE CISPR 22 limits is required. The shielded variant costs modestly more per unit but can eliminate the need for additional ferrite beads or shield cans on adjacent signal traces.
