Power Inductors - What can be done in SimSurfing

The following introduces what can be done in SimSurfing for power inductors.

Finding the power inductors you are searching for

As shown below, power inductors can be searched from various conditions.

  1. Applications: Specify General /Automobile
  2. Specifications: Inductance, outer dimensions, rated current, and DC Resistance
  3. Murata Part Numbers
  4. Desired operating conditions in the basic circuit of a DC-DC converter
  5. Desired current waveform to be input into the product

* For items 4 and 5, use the "Simulate" button on the following page.

Confirming Characteristics

The various characteristics of rf inductors can be displayed in graphs.

Impedance, ESR, reactance, phase, admittance, conductance, susceptance, inductance, Q, transmission characteristics (S21), and reflection characteristics (S11)

In the graph, the characteristics can be compared easily, because the characteristics of multiple items can be overwritten.

* In the XY axis of the graph, the Linear/Log can be switched and the display range can be set.

Acquiring Data used in Circuit Simulations

The S-parameters and SPICE models (Netlist) that can be used in commercial and free circuit simulations can be downloaded for the products displayed in SimSurfing.
* For some part numbers, data cannot be output.
