38 2 345 jst b this, the thinnest, 2.5mm (.098") pitch connector, is 8.1mm (.319") in height after mounting and 3.8mm (.150") in width. it is designed to meet the demand for the high- density connection of internal wires to printed circuit boards. it is compact, highly reliable and low in cost. features compact and slim this connector is designed to be compact and unusually thin. it measures only 8.1mm (.319") high after mounting and is just 3.8mm (.150") wide. highly reliable contact the contact has long dimples near the center that ensure continuity of low voltage and low current circuits at all times, even under conditions of vibration and abusive prying. polarizing guides the header and housing have guides to prevent improper mating. whisker prevention the contact material is treated with a reflow process, and the square post is copper-undercoated and tin/lead-plated for whisker prevention. easy and effective crimping although the contact is compact, it has a long wire strip length, 2.60.4mm (.102".016"). this long length is very useful for automatic crimping and when crimping shielded wires. specifications current rating: 3a ac, dc (awg#22) voltage rating: 250v ac, dc temperature range: -25 ? c to +85 ? c (including temperature rise in applying electrical current) contact resistance: initial value/10m ? max. after environmental testing/20m ? max. insulation resistance: 1,000m ? min. withstanding voltage: 800v ac/minute applicable wire: awg #32 to #22 applicable pc board thickness: 0.8 to 1.6mm(.031" to .063") * contact jst for details. standards 0 recognized e60389 1 certified lr20812 2 r75089 eh connector disconnectable crimp style connectors 2.5mm (.098") pitch crimp radial tape
