Mill-Max 4428-0-43-15-04-14-10-0 socket receptacle

Mill-Max has added a microminiature option to its organic fibre plug (OFP) receptacle line-up. The 4428-0-43-15-04-14-10-0 socket receptacle is the company’s smallest OFP receptacle. Optimised for high-density packaging down to 1 mm pitch, this microminiature, ultralow-profile receptacle accepts 0.008 to 0.013″ device leads or mating pins and can be soldered into a hole as small as 0.030″.

Mill-Max’s OFP solder barrier receptacles are discrete sockets for through-hole soldering into printed circuit boards. These open-bottom receptacles are fitted with OFPs to prevent contamination of the internal contact during the soldering process. When the device/mating lead is plugged into the receptacle, the OFP is knocked out, allowing the mating lead to pass through the fingers of the internal contact and make a reliable electrical connection. The 4428 features an open-bottom construction designed for pin pass-through requirements such as board-to-board or board-to-module interconnection.

The 4428 is also available packaged on tape and reel, part number 4428-0-67-15-04-14-10-0. Tape and reel packaging permits these through-hole components to be placed simultaneously with surface-mount parts on pick-and-place assembly lines, eliminating the need to hand place the receptacles in an additional manufacturing step.

The 4428 features a gold-plated, precision-machined brass shell assembled with the company’s #04 gold-plated beryllium copper contact clip with a 2 A current rating.
