1 this low profile box header is best suited for high-density, low-cost internal connections in office automation equipment. features ?interchangeability this header was designed to mate with the receptacle side of connectors conforming to mil-c-83503, including jst? ra connector. ?low cost the posts are selectively gold-plated at their mating end and tin-plated on their solder side. this reduces costs without hampering the connector's effectiveness. (headers with completely tin-plated contacts are also available.) ?low-profile the header has a low profile with a mounting height of 19.0mm when a plug with a strain relief is used. this height is approximately 10.0mm lower than the mounting height of the conventional mil-c-83503 header and thus maximizes the efficient use of space in electronic equipment. ?no contamination by flux or cleaning fluids sufficient stand-off area is provided to prevent flux and cleaning fluid contamination. specifications ?current rating: 1.0a ac, dc ?voltage rating: 300v ac, dc ?temperature range: (including temperature rise in applying electrical current) -55?c to +125?c(gold-plated) -55?c to +105?c(tin-plated) ?applicable pc board thickness: 1.6mm * rohs compliant products are published. * refer to "general instruction and notice when using terminals and connectors" at the end of this catalog. * contact jst for details. standards 0 recognized e60389 1 certified lr20812 rk header shrouded headers 2.54mm pitch
