Frequently Asked Questions
How does the Tiger Eye contact design in SFM-145-02-S-D-A-K improve reliability over standard socket contacts?
The Tiger Eye contact uses a dual-beam spring design that increases contact normal force to approximately 100 grams per contact, significantly improving gas-tight electrical connections compared with single-beam sockets. This makes SFM-145-02-S-D-A-K rated for higher mating cycle counts and more reliable in vibration-prone environments with its 30 µin gold mating finish.
For a 90-signal dual-row interface, how does the 0.050" pitch of SFM-145-02-S-D-A-K compare with standard 0.100" pitch alternatives?
At 0.050" pitch, the SFM-145-02-S-D-A-K accommodates 90 contacts in a 2.375 inch body length, whereas an equivalent 0.100" single-row header would need approximately 4.4 inches. The dual-row 0.050" format roughly halves the PCB footprint, enabling compact backplane or module designs where board area is constrained.
Is SFM-145-02-S-D-A-K compatible with RoHS-compliant lead-free assembly processes?
Yes. The termination finish is tin over a nickel barrier, which is fully compatible with SAC305 lead-free solder reflow at peak temperatures up to 260°C. The gold-plated mating contacts remain unaffected by reflow, so the connector meets RoHS requirements and can be processed on standard lead-free SMT lines without any profile adjustment.
