Frequently Asked Questions
How many contacts does the SFM-142-L2-H-D-A have and what current can each carry?
The SFM-142-L2-H-D-A has 84 positions arranged in a dual-row configuration. Each gold-plated contact is rated at 1A per pin, making it suitable for mixed signal and power distribution applications requiring reliable current handling across all 84 pins.
For a compact mezzanine card design, what board spacing does the SFM-142-L2-H-D-A provide?
The SFM-142-L2-H-D-A provides a 2mm stacking height between mated boards, allowing extremely compact mezzanine card assemblies. Combined with its 0.050" (1.27mm) pitch, the connector supports high pin density layouts on PCBs with minimal board-to-board clearance requirements.
In what temperature environments can the SFM-142-L2-H-D-A operate reliably?
The SFM-142-L2-H-D-A is rated for operating temperatures from -55°C to +125°C, making it suitable for industrial, automotive, and military-grade applications that experience extreme thermal cycling or elevated ambient temperatures over the product lifetime.
When should a designer choose SFM-142-L2-H-D-A over a lower-reliability socket strip?
Select the SFM-142-L2-H-D-A when your design requires 84 pins at 0.050" pitch with gold-plated contacts and extended temperature performance from -55°C to +125°C. Its high reliability rating is particularly beneficial in aerospace, defense, and industrial automation applications where connector failure is not acceptable.
