OARS-1Z

Open Air Zero Ohm Jumpers OARSZ Series • • • • • • Flameproof Low termination stress Lead flexible for thermal expansion Solderable pads (60/40 solder pads) Open air design provides coller operation Off board design ideal for high voltage applications Applications: Zerohm Jumpers or Crossovers are basically interconnection devices between points on a PC board. Typically, they are used to connect two points on a PC board due to other circuit paths which must be crossed over. The OARS Jumper is supplied on tape and reel to support high volume placement. OARS Zero Ohm Specifications: • 65 amp continuous @25°C (Board Dependent) • The dielectric withstanding characteristic of typical jumpers is limited by their encapsulation. However, dielectric withstanding of the OARS style jumper is limited only by: 1) physical separation of the solder pads; and 2) the height of the part off the pc board.
