Mill-Max Micro-Miniature Organic Fibre Plug® Receptacle

Press release date: Nov 10, 2012

Mill-Max has added a micro-miniature option to our organic fibre plug® receptacle lineup.  The newest Mill-Max socket receptacle, 4428-0-43-15-04-14-10-0, is our tiniest OFP® receptacle ever.  Optimized for high-density packaging down to 1 mm pitch, this micro-miniature, ultra-low profile receptacle accepts .008”-.013” device leads or mating pins and can be soldered into a hole as small as .030.”

Mill-Max’s Organic Fibre Plug (OFP®) solder barrier receptacles are discrete sockets for through-hole soldering into printed circuit boards.  These open bottom receptacles are fitted with Organic Fibre Plugs® 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.  Like all Mill-Max OFP® receptacles, 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 reel, part number 4428-0-67-15-04-14-10-0.  Tape & reel packaging permits these through-hole components to be placed simultaneously with surface mount parts on pick-’n-place assembly lines – eliminating the need to hand place the receptacles in an additional manufacturing step.

Mill-Max 4428 features a gold plated, precision-machined brass shell assembled with our exclusive #04 gold plated beryllium copper contact clip with a 2 amp current rating.
