thickness and shape are very important

Traces the temperature rise can be applied continuously determines the maximum safe current value. Alignment with variable width and alignment sensitivity can get the best combination of temperature rise. The temperature of copper is limited to the PCB material has a glass transition temperature (135 ℃), and the maximum operating temperature of Minisens 125 ℃. For a margin of safety considerations, it is best to take the line of work at temperatures lower than 115 ℃ (UL recommends no more than 100 ℃). In order to maintain the temperature level, the trace width, thickness and shape are very important.

For small current (less than 10A), is recommended to do a few laps primary alignment to increase the magnetic field generated by the primary current. On a single trace, Minisens best to walk around the line width greater than the width of the bottom trace (to reduce the temperature rise). We call this design is called "multi-turn."High insulation from the improved creepage distance and isolation spacing, because the primary conductor (four laps to go line) in low voltage electronic components located opposite the PCB. In this case, to ensure that two distances are 8mm (PCB features: 1.6mm/70μm Cu) (track width: Minisens under 0.78mm, other places 3mm).

Other techniques can be used to further increase the sensitivity, as in the above Minisens with a "jumper" and the PCB traces form a loop, or between different PCB layers multiple laps. Measuring large current, transmitter can be positioned in a place far away from the primary conductor.Many parameters can be Minisens nonvolatile memory chip for configuration. They can be used to adjust the transmitter gain, offset, polarity, temperature drift and gain algorithm (proportional to VDD or irrelevant).a sensitivity of 130mV / A, for 15A current output generated voltage of 2V.
