What are the key features of LSHM-120-L3.0-F-DV-A-S-K-TR?
- 40-position 0.50 mm pitch hermaphroditic board-stacking connector with integrated EMI shielding for noise immunity
- 3.0 mm board-to-board stack height (Razor Beam series) enables low-profile shielded mezzanine interconnections
- Shielded (S) construction reduces crosstalk and electromagnetic interference in multi-GHz differential signal routing
- Tape-and-reel (TR) packaging supports automated SMT pick-and-place assembly for volume PCB production
What is LSHM-120-L3.0-F-DV-A-S-K-TR used for?
LSHM-120-L3.0-F-DV-A-S-K-TR is designed for EMI-sensitive board-to-board mezzanine interconnections in RF front-end modules, 5G wireless platforms, and high-frequency computing systems. The integrated shield reduces crosstalk between differential pairs operating at multi-GHz rates across 40 contacts at 0.50 mm pitch, providing better signal fidelity than the unshielded variant. This connector is preferred in applications where adjacent board-level interference or dense RF environments could degrade high-speed serial link performance.

Frequently Asked Questions
What advantage does the shielding in LSHM-120-L3.0-F-DV-A-S-K-TR provide over unshielded variants?
The S designation in LSHM-120-L3.0-F-DV-A-S-K-TR indicates integrated EMI shielding that reduces crosstalk and electromagnetic coupling at signal frequencies above 1 GHz, where unshielded 40-pin mezzanine connectors at 0.50 mm pitch can introduce inter-connector interference. The shield improves insertion loss and maintains differential pair integrity in high-density RF module stacking and communications board designs.
Which RF or high-speed module designs specifically require LSHM-120-L3.0-F-DV-A-S-K-TR's shielded construction?
LSHM-120-L3.0-F-DV-A-S-K-TR is specified for RF transceiver modules, 5G mmWave daughter-cards, and radar sensor boards operating above 10 GHz, where electromagnetic crosstalk between the 40 pins at 0.50 mm pitch could corrupt differential signal pairs. The 3.0 mm stack height combined with EMI shielding also suits FPGA-to-RF interface stacking in phased-array antenna systems requiring tight electromagnetic isolation.
How should engineers choose between LSHM-120-L3.0-F-DV-A-N-K-TR and LSHM-120-L3.0-F-DV-A-S-K-TR for a board-stacking design?
Engineers should select LSHM-120-L3.0-F-DV-A-S-K-TR when signal frequencies exceed 1 GHz or when the 40-pin mezzanine board operates in environments with nearby RF interference that could couple into the 0.50 mm pitch connector. The shielded version adds a small cost premium over the unshielded N variant but prevents EMI-induced bit error rate degradation in high-speed serial links such as PCIe, USB 3.0, or proprietary multi-gigabit differential protocols.
