Low-cost SOT jumpers eliminate PCB re-design headaches

TopLine offers SOT Jumper components, a low-cost way to short out (JUMPER) PCB circuitry without the need to redesign or spin a whole new board. Their components short-out specific pins together with less than 50 milli-ohms resistance. “SOT Jumpers are a quick and easy to replace unneeded circuits,” states Martin Hart, TopLine’s president. “Our SOT23 Jumpers mount on the PC Board using normal SAC305 lead free solder paste, just as regular components.” In the most common configuration, for example, Pin 1 is shorted to Pin 3; another configuration shorts Pin 2 to Pin 3. The company also makes a version with Pin 1, Pin 2 and Pin 3 all shorted together. Their series of jumpers withstand 75VDC at 100mA with 350mW power dissipation. Their operating temperature range from -65C to +150C.
