TopLine has launched SOT Jumper components, a low-cost way to short out (jumper) PCB circuitry without the need to redesign or spin a whole new board. TopLine SOT23 components short-out specific pins together with less than 50m 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. 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 range from -65⁰C to +150⁰C. Standard and halogen free versions are available, and versions with up to 8 shorted pins are available.
TopLine manufactures CCGA Column Grid Arrays, solder columns, and a wide range of daisy chain semiconductor packages, and offers a complete range of daisy chain test chips for process development, experimentation, machine evaluation, solder training, and SMT assembly practice. TopLine products provide hands-on learning for engineers. TopLine is a one-stop source for all dummy components. Contact TopLine Corp. at (800) 776-9888 or email: info@TopLine.tv.
