Würth Elektronik WR-FPC LIF connector

Small and flexible flat-ribbon cables are widely used in LCD screens, board-to-board connections for medical equipment, test and measurement devices, industrial applications, entertainment electronics and more. In many of these applications, it is not important to have a vibration-free interlock for the plug-in connector. For such applications Würth Elektronik offers its easy-to-assemble LIF (low insertion force) connector, the WR-FPC.

Suitable for SMT pick-and-place assembly systems, connectors in the 1 mm grid format are available in a variety of versions, from 4 to 30 pins, in horizontal and vertical plug-in directions. Besides serving as sockets for flat flexible cables, they are also intended for use as connectors for flexible printed circuit boards (hence the designation FPC).

The rated current is 1 A and the operating voltage 125 V. To ensure a high degree of elasticity, low wear and tear and low resistance (30 mΩ), Würth Elektronik has selected phosphor bronze as the material for the contacts. The connectors have an undercoat of nickel to prevent the so-called tin whisker phenomenon.
