What are the key features of TFM-146-04-F-D-LC?
- 92 dual-row through-hole contacts at 0.050-inch (1.27 mm) pitch enabling high-density board-to-board signal routing in space-constrained PCB layouts
- Tiger Eye contact geometry provides superior mating retention and vibration resistance suitable for harsh-environment and high-reliability applications
- Low-crosstalk (LC) contact spacing variant optimized for high-speed differential signal pairs and adjacent channel isolation in data-intensive systems
What is TFM-146-04-F-D-LC used for?
The TFM-146-04-F-D-LC is designed for high-density signal interconnect in telecommunications switching equipment, data center line cards, and embedded computing modules where the 0.050-inch pitch through-hole terminal strip maximizes contact count per unit of board space. The LC (low-crosstalk) variant is especially suited for high-speed differential signal routing between daughter cards and backplanes operating at frequencies above 100 MHz. Defense, aerospace, and industrial automation applications also rely on the Tiger Eye contact geometry for consistent mating retention across extended temperature and vibration profiles.

Frequently Asked Questions
How many contacts does TFM-146-04-F-D-LC provide, and what pitch spacing is used?
The TFM-146-04-F-D-LC provides 92 contacts in a dual-row through-hole configuration on a 0.050-inch (1.27 mm) pitch. This fine pitch allows routing nearly double the signal count of standard 0.100-inch headers in the same board footprint, making it ideal for high-density daughter card and backplane interconnect applications.
What does the LC designation mean in TFM-146-04-F-D-LC, and at what signal frequencies is it most beneficial?
The LC suffix indicates a low-crosstalk contact configuration where adjacent contacts are spaced and shielded to minimize capacitive and inductive coupling. This variant provides measurable crosstalk reduction for differential signals operating above 100 MHz, making TFM-146-04-F-D-LC a preferred choice for SerDes, LVDS, and high-speed bus interfaces in telecom and data communication line cards.
For a compact backplane design, how does TFM-146-04-F-D-LC compare to a standard 0.100-inch pitch dual-row connector of equal pin count?
At 0.050-inch (1.27 mm) pitch, the TFM-146-04-F-D-LC occupies approximately half the board length of a 0.100-inch (2.54 mm) pitch connector carrying the same 92 contacts. This size reduction enables tighter card spacing in blade-server and telecom chassis designs, freeing board area for additional circuitry. The Tiger Eye contact retention also maintains reliable mating under the vibration conditions common in rack-mount equipment.
