TOFLAT Leafconn Leafconn is a connecting lead wire best suited for internal wirings of electronic apparatus. FFC is composed of conductors of rectangular section laid in parallel at a specified pitch and sandwiched between plastic film tapes. The joining surfaces of the upper and lower tapes are bonded together by heat and pressure or adhesive applied to them. It is used for connectors between circuit boards and for connectors of circuit boards to electronic parts in electronic apparatus such as printers, copying machine, stereo players, TV sets, video tape recorders, telephone sets, etc. It is highly economical and reliable. New lineup: Halogen-free FFC is an environmentally friendly cable and Gold-plated FFC eliminates the production of whiskers. Features [Standard FFCs] Economical as compared with FPC. Highly flexible, and durable against repeated bending . Various length and number of conductors available by request. Since the cable itself can also be used as the connector contact, it makes the connecting easy. As the rectangular conductor is better in heat radiation than the round one, current capacity can be made greater per given sectional area. It can be used in any bent form. Saving the wiring space, it increases the packaging density. [Halogen-free FFC] An environmentally friendly cable Does not contain a halogen-based flame retardant or antimonid. Has the same features including flame retardance as Leafconn connecting lead wires, which conventionally use a halogen-based flame retardant. [Gold-plated FFC] To eliminate whiskers High wire-connecting reliability without producing whiskers. Excels in contact stability for use with a connector. Superior corrosion resistance and enables soldering. Gold-plated FFC Shielded type FFC · Bending, taping at both faces, stamping and shield-processing are available for all FFC types. Enquire for details. All of our FFC types are lead-free. Applications Lead wires for the connection between printed circuit boards and for the connection of the boards with electronic parts within electronic apparatus such as printers, copying machines, stereo players, TV sets, video tape recorders, telephone sets, fax machines, etc. Characteristics Characteristics 1.25mm pitch 1.00mm pitch 0.5mm pitch Conductor used 0.1 ×0.8 0.05 ×0.8 0.035 ×0.8 0.1 ×0.7 0.05 ×0.7 0.035 ×0.7 0.1 ×0.6 0.05 ×0.6 0.05 ×0.3 Uses For general purpose For flexiblity For high flexiblity For general purpose For flexiblity For high flexiblity For general purpose For flexiblity For high density packaging Conductor resistance Ω/m 0.260 0.600 0.935 0.300 0.700 1.100 0.360 0.800 1.700 Rated current (A) (reference) 1.0 0.5 0.4 0.9 0.5 0.3 0.8 0.4 0.2 Insulation resistance between conductors 500V DC, 100MΩ or higher 500V DC, 100MΩ or higher Withstand voltage between conductors 1,000V DC, one minute 500V DC, one minute 300V DC, one minute Service temperature -3080(105) 180 bending 20times or more 40times or more 100times or more 20times or more 40times or more 80times or more 20times or more 40times or more 40times or more Rolling (10R) 100,000 times 4,000,000 times 10,000,000 times 80,000 times 4,000,000 times 8,000,000 times 80,000 times 3,000,000 times 2,000,000 times Specifications Items 1.25mm pitch 1.00mm pitch 0.5mm pitch Conductor size (mm) 0.035 ×0.8 0.05 ×0.8 0.1 ×0.8 0.035 ×0.7 0.05 ×0.7 0.05 ×0.6 0.1 ×0.7 0.1 ×0.6 0.05 ×0.3 Cable type K,R K,R,V K,R, V,Y K,R K,R,V V K,R, V,Y V,Y K,R Conductor pitch (P) (mm) 1.25 ±0.1 1.00 ±0.08 0.5 ±0.05 No. of conductors (n) 440 540 1050 Total pitch (PA) (mm) 1.25(n-1) ±0.15 1.00(n-1) ±0.10 0.5(n-1) ±0.06 Overall width (W) (mm) 1.25(n+1) ±0.20 1.00(n+1) ±0.10 0.5(n+1) ±0.07 Margin width (M) (mm) 1.25 ±0.2 1.00 ±0.15 0.5 ±0.10 Length of bare end (S) 2,3,4,5,6 ±1.0 2,3,4,5,6 ±1.0 2,3,4,5,6 ±1.0 Reinforcing tape length (B) (mm) 6,8,10,15 ±2 6,8,10,15 ±2 6,8,10,15 ±2 Insulation length (L) (mm) 209000 209000 201000 Terminal thickness (T) (mm) 0.3±0.05 (for connector compatible type) Conductor thickness (for soldering) 0.3±0.05 (for connector compatible type) Conductor thickness (for soldering) 0.3±0.05 (Compatible type) Insulating tape thickness (mm) 0.1 0.045 0.06 0.1 0.1 0.045 0.06 0.1 0.06 0.045 UL grade 2896,20624, 20706,2737 2896,20624, 20706,2737 2896,20624, 20706
