Learn about the story and mission behind VSTSA-APP
VSTSA-APP is committed to providing professional, accurate, and easy-to-use inductance calculation tools for engineers, students, and makers, making complex coil design simple and efficient.
We believe that excellent tools should be both professional and easy to use. In the fields of electronic design and RF engineering, precise inductance calculations are key to successful design. However, traditional calculation methods often require consulting extensive materials and performing tedious unit conversions, which is not only time-consuming but also error-prone.
VSTSA-APP was born to solve these problems. We encapsulate complex formulas and calculation processes in an intuitive interface, allowing users to focus on design itself rather than being troubled by calculation details.
To become the preferred magnetic component design tool for engineers and electronics enthusiasts worldwide.
We are committed to continuously improving and expanding VSTSA-APP's functionality, supporting more types of coil geometries and calculation scenarios. In the future, we plan to add more advanced features, including:
Core principles that guide our work
We ensure all calculation results are rigorously verified, providing professional-grade accuracy and reliability
We believe complex features should be presented through simple and intuitive interfaces, making them accessible to everyone
We listen to user feedback, continuously improve our products, and ensure we meet real-world needs
We constantly explore new technologies and methods to provide better tools and experiences for users
