SEAT 2013 - SElection Assistant of TDK components Ver.5.3.0[2015/Dec/21]

Discontinued in the end of September 2018.

Major Functions

More Than Ten Thousands Components are Included

TDK components such as chip beads, inductors (coils), ceramic capacitors, 3-terminal filters, common mode filters, varistors, baluns, NTC thermistors are included.

Displaying Impedance Characteristics

Impedance, inductance, Q, and tanδ characteristics can be displayed.

Displaying S-parameter Characteristics

Not only |S11| and |S21| characteristics, but also phases, group delay time, and Smith charts can be displayed.
Mixed mode S-parameters can be used to evaluate differential (balanced) components.
Arrays can be analyzed using multiple ports, which makes it easy to evaluate crosstalk.

Displaying S-parameter Characteristics

Displaying DC bias and temperature characteristics

It is possible to show the DC bias and temperature characteristics for inductors and capacitors, which are mainly used for power circuits.

Pulse Response Simulation

It is possible to simulate both single line and differential transmissions. This makes it easy to confirm the efficiency of ferrite beads and common mode filters.

TDR Simulation

TDR is used to evaluate the characteristic impedance of high-speed differential (balanced) components.

TDR Simulation

Temperature Rise Simulation

It is possible to show the temperature rise characteristics of inductors and capacitors, which are mainly used for power circuits, for direct current and ripple current.

Temperature Rise Simulation

ESD Simulation

It is possible to simulate the high-voltage suppression effect of chip varistors.

NTC Thermistor Simulation

NTC thermistors resistance changes depending on the temperature. This simulation shows the output voltage and temperature differences when the component is used in a circuit.

NTC Thermistor Simulation

User-Defined Filter

It is possible to create virtual components by combining various components.
This is helpful, for example, when creating a discrete filter by combining an inductor and capacitor.
This filter would be able to handle both two-port and four-port components.

Characteristic Impedance Calculator

This tool can calculate the characteristic impedance based on the size of the printed circuit board.
This tool can be used for both single lines and coupled lines, and for other lines such as coaxials, strips, coplanars, and microstrips.
In addition, you can create S-parameters for these lines. So, if this tool is used along with the user-defined filter, it is possible to create a layout with lines between components.
