What is thick film technology and what can it do?

The world of electronics and electrical engineering is characterized by constant progress and innovation. One such innovation is using thick film technology in the production of resistors, which are a crucial component in a variety of power electronics applications.

In this blog article we will take a closer look at this special resistor technology and explore its applications and advantages.

What are the main characteristics of resistors manufactured using thick film technology?

Resistors manufactured using thick film technology are among the most innovative types of resistors for high-performance electronics, and are also known as thick film resistors.

Compared to conventional resistors, thick film resistors are very powerful and offer a wide range of ohmic values and tight tolerances. They are also characterized by high temperature resistance and reliability.

Main features:

With a thickness of about 10 µm, they are approximately a thousand times thicker than thin-film resistors, which is why they are also called thick film resistors
They have an ohmic value range between 0,05 Ω und 100 GΩ
The maximum operating temperature range is between +150 °C und +275 °C
The voltage range goes up to 200 kV (even higher when connected in series)

Our development team is always working on smaller, more powerful and cost-effective resistors.

Applications of resistors produced using thick film technology?

The uses are diverse and range from e-mobility to aerospace applications.
Some of the main areas are:

E-mobility: Our resistors play an important role in electric vehicles, especially in inverters and battery management systems.
High speed trains: Our resistors are used in energy distribution and control.
Aerospace: Due to their reliability and temperature resistance, our resistors are indispensable in the aerospace technology.
Medical technology: Precision is crucial in medical technology. Our resistors contribute to the manufacturing of high-quality medical devices.
Energy transmission and distribution: They are also applied in high-voltage applications such as HVDC (high voltage direct current) and smart grids.

The housing and parameters can be custom designed to meet the specific requirements of our customers and their applications. This allows the optimal utilization of available space to deploy components with the highest power density.

Manufacturing of resistors produced using thick film technology

Our thick film technology resistors are made from a layer of metal oxide paste, which is applied to a high-quality ceramic substrate using a screen printing process.

The production process involves several steps:

preparation of raw materials
applying of the resistance layer using a screen printing process
drying and firing
coating
stabilization process as well as quality testing

The manufacturing of resistors requires precision and time to ensure the quality of our products. Stable production parameters play a crucial role in achieving our highest quality standards.

What do our customers need to watch out for when buying thick film resistors

These 3 factors are crucial when purchasing thick film technology resistors:

Ohmic value and tolerance:
Ensure the selected ohmic value meets the requirements of your system. It is also important to check the required tolerance range to avoid unnecessary costs.
Power and voltage rating:
The correct operating power or voltage helps prevent overheating.
Special requirements:
In some cases pulsed applications need to be considered. Please contact us if that is the case. In addition, temperature coefficient, voltage coefficient and partial discharge should not be overlooked.

Choosing the right resistor influences the performance and safety of your electronic device. Therefore, careful planning and consideration of your application requirements are important. If you have any questions, our sales and technical staff would be pleased to help you select the best resistors for your needs.
