TopLine Low-cost Zero Ohm SOT23 Jumpers Eliminate PCB Redesign Headaches

TopLine offers near zero-ohm SOT23 Jumper components, a low-cost way to short out Printed Circuit Board circuitry (PCB) without the need to redesign or spin a whole new board. TopLine jumper components are available in a variety of component outlines and connect (short-out) specific pins together with less than 50 milli-ohms resistance.



“Jumpers are a quick and easy way to replace unneeded circuits,” states Martin Hart, TopLine’s President. “For example, our SOT23 Jumpers mount on the PC Board using normal SAC305 lead-free solder paste, just like regular components.”

TopLine offers all popular configurations. For example, Pin 1 is shorted to Pin 3. Another configuration shorts Pin 2 to Pin 3. TopLine also makes a version with Pin 1, Pin 2 and Pin 3 all shorted together.

TopLine’s series of SOT23 Jumpers withstand 75VDC at 100mA with 350mW power dissipation. Their operating temperature ranges from -65⁰C to +150⁰C. Standard and halogen-free versions are available. Other versions with up to 8 shorted pins are available. For more information, visit
