Key Features
- 90-position dual-row Tiger Eye terminal strip at 0.050" (1.27 mm) pitch provides ultra-high signal density for compact mezzanine board stacking
- 23 mm stacking height option accommodates PCB assemblies with components or heat spreaders between mating boards
- Tiger Eye contact technology delivers enhanced wipe action for gold-on-gold reliability rated at 500+ mating cycles
- High-reliability design qualified for aerospace, defense, and mil-spec applications with extended operating temperature from -55°C to +125°C
Applications
The TFM-145-23-S-D is designed for high-density mezzanine board stacking in defense avionics, radar processing modules, and rugged embedded computing systems where 90 signals must be routed reliably at 0.050" pitch. Its 23 mm stacking height accommodates thick PCBs, heat spreaders, or RF shielding between daughter and carrier boards. The Tiger Eye contact design ensures consistent low-resistance connections across thousands of hours in vibration-prone or thermally cycling environments.

Frequently Asked Questions
What is the stacking height and position count of the TFM-145-23-S-D?
The TFM-145-23-S-D provides a 23 mm board-to-board stacking height with 90 total positions arranged in a dual-row 0.050" (1.27 mm) pitch configuration. This height accommodates interposing components, heat spreaders, or EMI shielding between paired PCBs in aerospace and defense mezzanine assemblies.
How many mating cycles are TFM series Tiger Eye connectors rated for?
SAMTEC Tiger Eye terminal strips in the TFM series are rated for a minimum of 500 mating cycles under standard conditions, with gold-plated contacts maintaining contact resistance below 20 mΩ throughout rated cycle life. This makes them suitable for field-replaceable compute modules and test fixtures subject to repeated insertion and removal.
For a defense avionics design at -55°C to +125°C, does the TFM-145-23-S-D meet temperature requirements?
Yes, the TFM-145-23-S-D is rated for operation from -55°C to +125°C, meeting the environmental requirements of MIL-DTL-55302 and similar defense interconnect standards. This range covers ground vehicle, airborne, and shipboard avionics environments, including cold-soak and hot operating conditions encountered in DO-160 and MIL-STD-810 qualification testing.
How does 0.050" pitch in the TFM-145-23-S-D compare to standard 0.100" pitch connectors for high pin-count designs?
At 0.050" (1.27 mm) pitch, the TFM-145-23-S-D achieves twice the contact density of a 0.100" (2.54 mm) pitch equivalent, fitting 90 positions in the footprint that a standard pitch connector would need for only 45 contacts. This is critical for VPX, VITA 46, and other high-density embedded computing form factors where PCB area is strictly constrained.
