2.54mm pitch/Connectors for FPC and membrane switch leads Specifications ––––––––––––––––––– • Current rating: The FDZ connector, a Zero Insertion Force (ZIF) connector, was developed to connect FPC and membrane switch leads. This combination of features allows greater freedom in internal wiring designs. No force is required to insert the leads. Once inserted, the leads are securely held and locked by moving the slide. The contact is double-sided to ensure greater reliability. • Double-sided contact • Zero insertion force and locking mechanism • Temporary board retention feature • Boss for polarity identification • Flux is not a problem Tin-plated copper foil lead/1.0A AC, DC Silver paste carbon-printed lead/50mA AC, DC • Voltage rating: 250V AC, DC • Temperature range: -40˚C to +85˚C (including temperature rise in applying electrical current) • Contact resistance: lnitial value/30m Ω max. After environmental testing/50m Ω max. lnitial value/10 Ω max. After environmental testing/15 Ω max. • Insulation resistance: 1,000M Ω min. • Withstanding voltage: 1,200V AC/minute • Applicable FPC and membrane switch lead: Conductor pitch/2.54mm Conductor width/1.3mm Mating part thickness/125 micron • Applicable PC board thickness: 1.6mm Note: FPC to be actually used should be checked for applicability. * Compliant with RoHS. * Refer to "General Instruction and Notice when using Terminals and Connectors" at the end of this catalog. * Contact JST for details.
