288 the fm connector, a miniature connector with a thickness of only 3.0mm (.118"), was developed to connect flexible flat cables (ffc) or flexible printed circuits (fpc) with a lead pitch of 1.0mm (.039") to printed circuit boards. it is ideally suited for connections inside high- density equipment or between mechanical units. the contact is constructed to ensure a stable connection and high reliability even under vibration and impact. connection is easy with a simple snap-in action. features ?compact having no complicated cam or slide mechanism, this connector is very small with a mounting height of only 4.4mm (.173") and a width of 3.0mm (.118"). ?double-sided contact this connector has highly resilient phosphor bronze contacts, each of which has two independent mating spring members that ensure continuity even when subjected to severe vibration. because each of the contacts simultaneously mates with both sides of the ffc or fpc, the engineer has greater freedom in designing his circuitry. ?simple snap-in action the ffc or fpc are securely connected by simply inserting their leads into the connector. ?surface mount model (smt) this connector is also available in a surface mount configuration. its housing is made of heat resistant resin so that it is not adversely affected during reflow soldering. because of its tiny size and ability to be surface mounted, this connector meets the demand for high-density mounting of components inside electronic products. specifications ?current rating: 0.5a ac, dc ?voltage rating: 50v ac, dc ?temperature range: -25?c to +85?c (including temperature rise in applying electrical current) ?contact resistance: initial value/20m max. after environmental testing/30m max. ?insulation resistance: 800m min. ?withstanding voltage: 500v ac/minute ?applicable ffc and fpc: lead pitch /1.0mm(.039") note: lead width /0.7mm(.028") mating part thickness / 0.33 +0.02 -0.03 mm(.013 +.0008" -.001" ) ?applicable pc board thickness: 0.8 to 1.6mm(.031" to .063") note: these are reference values. ffc/fpc to be actually used should bechecked for applicability. * contact jst for details. standards recognized file no. e60389 certified file no. lr20812 fm connector connectors for ffc and fpc 1.0mm (.039") pitch emboss tape
