LT Spice Models for E-Series

Please download the LT SPICE Model from the table at the bottom of the page . Click zip file to save on Desktop/specific folder.

LT Spice Library models

Design engineers and product development highly depend on the schematic design and simulation tools before finalizing the suitable high frequency coils for the product design.

CWS provides LT Spice simulation models for the designer in mind to make it easy for selecting the right component for the circuit design.

LT Spice how it works

LT Spice Schematic and simulation platform is provided by Analog devices ( for easy of circuit modelling. This platform has become industry standard for many other simulation software and tools. This platform saves time, cost and efforts in making trials on real circuits.

Many of the design engineers, educational institutions uses LT Spice for circuit designing and simulating the circuits by importing the library components from various manufacturers.

Various components manufacturer like Inductors, transformer, coils, capacitors, resistors and other active and passives devices manufacturers have made Library of components which users can download and link with in their LT Spice circuit design and simulation.

For more details on the LT Spice please visit

We suggest designers to download the latest version from the above link. Analog Devices Inc keep updating the software for better design and simulation tools.

How to use the LT Spice is provided in the above link from Analog Devices.

CWS Coils: LT Spice models

With design engineers, design professionals and education institution in mind CWS Coils has made LT Spice model library of the various inductors.

Designers can download the library in their computer system and link with library to the Lt Spice software for the Schematic design modeling and simulation.


Enclosed here is the DEMO circuit using LT Spice showing how the CWS Coil inductor LT Spice model is used.

Sample Schematics including a CWS component model also enclosed.

How to Link the LT Spice model Library

Example instruction for the linking the LT Spice model library of Helical Power Inductor.

LTspice Library for CWS Coils Power Inductors.

Version 2.0.

Assembled on (Sep 2018)

By Coil Winding Specialist Inc

This LTspice library contains all models for CWS Coils Power Inductors, Part Numbers:



















Please keep in mind that real components can vary in the range given in the data sheets.

The values are based on the data provided in the datasheet.


Installation of COILWS Model Library


The zipped model library folder of the COILWS Power Inductors for LTspice comprises the following 2 folders:

- CWS_Power Inductor_LTC_Library , This folder contains the ASCII data file (CWS_Power Inductors.lib) that represents the actual library

- CWS_Power Inductor , This is the symbol data file that contains the graphics information required by the graphic user interface



LTspice XVII


1) Please make sure that LTspice software is not running.

2) Copy the (CWS_Power Inductor_LTC_Library) folder to C:/

3) Go to the (sym) folder. You will find it in the installed (LTspiceXVII) folder in the (Documents) folder. The path should be like this:

C:Users"USER NAME"DocumentsLTspiceXVIIlibsym

and copy the (CWS_Power Inductor) folder.

4) On the next start of LTspiceXVII, open a New Schematic, Click on the Component library (or press on F2), you will find the [CWS_Power Inductor] folder appears in the LT Spice Component library.

5) Double Click on [ CWS_Power Inductor] folder and choose your Part number.
