Frequently Asked Questions
What makes the Tiger Eye contact design in the TFM-147-21-SM-D superior for high-cycle applications?
SAMTEC's Tiger Eye contact geometry provides a dual-beam wiping action that removes oxidation and debris from mating surfaces on each insertion cycle. Rated for thousands of mating cycles, the TFM-147-21-SM-D maintains low contact resistance—typically under 20 milliohms—making it ideal for hot-swap modules and field-replaceable cards in telecom and industrial systems.
What is the total pin count and row arrangement of the TFM-147-21-SM-D?
The TFM-147-21-SM-D provides 94 positions in a dual-row configuration on a 0.050" (1.27 mm) pitch. This high-density layout gives designers access to a large number of signal, power, and ground pins in a compact surface-mount footprint suited for multilayer PCB designs in aerospace and medical instruments.
Can the TFM-147-21-SM-D operate reliably across the full military-grade temperature range?
Yes, SAMTEC TFM-series Tiger Eye connectors are built to withstand extended temperature ranges. The TFM-147-21-SM-D supports operating temperatures from -55°C to +125°C, qualifying it for military-grade, aerospace, and industrial applications that demand connector reliability across wide ambient temperature cycles and thermal shock conditions.
How does the 0.050" pitch of the TFM-147-21-SM-D compare to standard 0.100" pitch connectors for board space savings?
The 0.050" (1.27 mm) pitch of the TFM-147-21-SM-D uses half the row spacing of a conventional 0.100" (2.54 mm) connector. For a 94-pin dual-row interface, this translates to roughly 50% reduction in connector length, freeing significant PCB real estate for other components in high-density embedded computing and telecom line-card designs.
