Frequently Asked Questions
How does the 0.050 inch pitch on TFM-120-32-S-D-LC compare with standard 0.1 inch pitch connectors for high-density PCB designs?
The TFM-120-32-S-D-LC uses a 0.050 inch (1.27 mm) pitch, which is half the spacing of a standard 0.1 inch (2.54 mm) pitch connector. This tighter pitch allows a 40-position dual-row configuration to fit in roughly half the board area, making it well-suited for compact designs in telecommunications and instrumentation.
What is the significance of the split board lock feature for mechanical retention in vibration-prone environments?
The split board lock on TFM-120-32-S-D-LC provides a mechanical anchor directly into PCB mounting holes, resisting vibration-induced connector displacement without requiring screws or additional hardware. For industrial or aerospace designs subject to mechanical shock, the board lock maintains the 40-pin mating alignment and reduces stress on solder joints.
Which contact finish does TFM-120-32-S-D-LC use, and how does it affect long-term reliability in industrial environments?
The TFM-120-32-S-D-LC uses a matte tin over nickel contact finish on 40 contacts. Tin finishes provide good solderability and corrosion resistance for indoor industrial environments, though designers in high-humidity or high-temperature settings above 85°C may consider gold-plated alternatives for superior long-term contact resistance stability.
What is the typical factory lead time for TFM-120-32-S-D-LC, and should procurement teams plan safety stock for production runs?
Samtec lists a factory lead time of approximately 2 weeks and 6 days for TFM-120-32-S-D-LC. For production builds with high volume requirements, procurement teams should account for this lead time and consider ordering safety stock, since surface-mount Tiger Eye connectors at 0.050 inch pitch may have limited spot-market availability.
