0.5mm (.020") pitch SMT connector.
Smaller in size and narrower in mounting
space than conventional type.
Features––––––––––––––––––––––––
• Secure mating
Cantilever type contact that has wiping effectiveness provides
secure mating by contact lock with favorable click-feeling.
• Distortion resistant construction
Guide ribs on both sides of plug and housing toward pitch
direction prevent dostortion.
• Versatile number of circuit and height
Number of circuits: 20 to 80
Height: 3.0mm (.118") to 10.0mm (.394")
• Reinforcing tab (under planning)
Reinforcing solder tab is available on request in order to ensure
secure mounting on PC board.
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/50m Ωmax.
After environmental testing/100m Ωmax.
• Insulation resistance: 50M Ωmin.
• Withstanding voltage: 100V AC/minute
* Contact JST for details.
