Key Features
- 30-position dual-row shrouded SMT receptacle at 0.050 inch (1.27 mm) pitch for high-density board-to-board interconnect
- Tiger Eye ELP contacts with 30 microinch gold over 50 microinch nickel provide contact resistance below 10 milliohms over 500+ mating cycles
- Shrouded housing design prevents mis-mating and protects 30 contacts from mechanical damage during assembly and field service
- RoHS-compliant tin-over-nickel termination finish supports lead-free SAC305 SMT reflow processes up to 260 degrees C
Applications
The TFM-115-22-S-D is designed for high-reliability board-to-board signal interconnect in industrial computing modules, test and measurement equipment, and telecom line cards requiring 30 signal channels at 0.050 inch pitch. The shrouded housing ensures foolproof polarized mating with the corresponding SAMTEC TFM header, preventing reversed insertion in production and field environments. Tiger Eye ELP contacts maintain signal integrity across hundreds of mating cycles, making this receptacle ideal for removable plugin modules in networking and data acquisition systems.

Frequently Asked Questions
What contact technology does the TFM-115-22-S-D use, and how many mating cycles does it support?
The TFM-115-22-S-D uses SAMTEC's Tiger Eye contact geometry with ELP (Extended Life Performance) plating, which consists of 30 microinch gold over 50 microinch nickel on the mating surface. This combination supports 500 or more mating cycles while maintaining contact resistance below 10 milliohms across all 30 positions, making it suitable for frequently replaced plugin modules in test equipment and hot-swap network line cards.
How does the shrouded housing of the TFM-115-22-S-D prevent mis-mating in dense multi-connector PCB layouts?
The shroud surrounding the 30 contacts acts as a mechanical key and polarization guide, accepting only the matching TFM header in the correct orientation and blocking reversed or offset insertion. In PCB layouts with multiple identical connectors placed within 5 mm of each other, this keying prevents assembly errors that would otherwise damage the 0.050 inch pitch contacts and require costly board rework in automated production environments.
What is the PCB footprint of the TFM-115-22-S-D and how much space must be allocated in the board layout?
The TFM-115-22-S-D has a body length of 0.875 inch and body breadth of 0.225 inch for the 30-position dual-row shrouded receptacle at 0.050 inch pitch. Designers should plan a courtyard envelope of approximately 1.0 inch by 0.4 inch including solder pad extensions and the shroud wall protrusion, with a 0.5 mm clearance to adjacent components to allow solder paste stencil printing and inspection access in SMT assembly.
Is the TFM-115-22-S-D a viable choice for high-speed differential pair routing in FPGA mezzanine designs?
Yes, the TFM-115-22-S-D supports differential pairs for protocols such as LVDS at frequencies up to several hundred megahertz and PCIe Gen 1 at 2.5 Gbps per lane when routed with controlled impedance PCB traces matched to 100 ohms differential. With 30 positions arranged in 2 rows at 0.050 inch pitch, the connector can carry up to 7 differential pairs plus ground and power signals, sufficient for a 4-lane PCIe or 4-channel LVDS camera interface in compact FPGA module designs.
