To measure the inductance of a device, intrinsic inductance of a circuit or more widespread distributed inductance, an LCR meter is the instrument of choice. It subjects the device under test (suitably discharged and isolated from any ambient circuitry that could energize it or create irrelevant pa...
so willvias in a multilayer board. The inductance of a via is on the order of nanohenries and depends primarily on its aspect ratio. Vias also have self-capacitance, and groups of vias have some mutual capacitance and mutual inductance. This leads to noise coupling between vias and c...
The housing also influences the PCB antenna's tuning frequency, for this reason, it is always recommended to measure the RF performance of the application in the final product configuration. 22/26 AN2972 Rev 9 AN2972 From design to production Figure 26. Impact of housing/packaging material...
two tracks close to each other) regarding the interference of electric and magnetic fields. The electric field is coupled via mutual capacitance between the signals. On the other hand, the magnetic field is coupled via mutual inductance between the ...
Dependent on the closed loop transducer model, it is possible to measure a di/dt of 50 to 400 A/µs or more. This makes them well suited for the short-circuit protection of semiconductors in power equipment. 3.2.9 Typical applications Closed loop transducers are particularly well suited ...
Relays also measure the prefault signals and can extrapolate them forward in time. This extrapolation is valid only for a few tens of milliseconds because the power system sources only remain stationary for a short period of time. Therefore, we simply use (8) and (9) to derive voltage and...
