Overview of Types and Applications of Thin-Film Resistors

There are currently different types of thin-film resistors on the market, and this includes ultra-precision thin-film resistors with a wide range of amazing properties. With these thin-film resistors, you get the best level of accuracy and tolerance, making them perfect for different applications. A key thing to understand is that there are other types of thin-film resistors on the market, each of which has a different level of tolerance designed to meet different needs.

When it comes to types of thin-film resistors, it’s important to note that the market is segmented into those with 0.1% tolerance, ultra-precision with 0.05% tolerance, and others. The market is also segmented based on application, and this includes automotive electronics, medical equipment, instrumentation, communication devices, and others.

Basically, these resistors are used in multiple industries, as mentioned earlier. They are vital for ensuring reliable communication in devices, stable performance in electronic appliances, increased precision in medical devices, and accurate measurements in different instruments. The main reason why thin-film resistors are essential for these applications is the accuracy and precision they offer. This further ensures optimal functionality and performance in diverse electronic systems.

Nickel Chromium Thin Film Resistors

These thin film resistors are designed based on the nickel-chromium resistive layer. This offers a more robust construction with increased performance at a low and affordable price when compared to other solutions, including thick film resistors. They are currently widely applied in LED lighting, LCD backlighting, and DC/DC converters.

Tantalum Nitride Thin Film Resistors

These types of resistors are also deployed in different applications, particularly in defence electronics, because of their long-lasting effects. However, you’ll also find them used for some medical applications like in implantable electronics. Tantalum Nitride thin film resistors are also used in oil and gas electronics, especially for downhole pump applications in drilling related tools. Other applications include telecommunications equipment and DC/DC converters.

Trends in the Global Thin-Film Resistor Market

There are many emerging trends in the global thin-film resistor market. This includes the growing need for precise electronic devices, increasing focus on energy efficiency and sustainability, utilization of the Internet of Things, and the rising demand for smaller electronic devices.

Some of the current trends in the market include smart home devices, wearables, renewable energy solutions, the adoption of advanced technologies and materials in design, and the growing popularity of electric vehicles. With these trends, the market is projected to experience continued growth as the demand for electronic components with high levels of performance continues to increase.

Anti-Sulfide Trends Fuel Demand for Thin Film Resistors

Construction equipment, commercial machinery, automotive circuitry, marine electronics, and welding equipment have all shown a high level of failure rates because of the high sulfur concentrations in polluted air, especially in countries like India and China. Basically, for highly industrialized regions, there’s a high level of sulfur in the air where electronic devices and appliances operate. This leads to failure in these devices resulting from sulfur contamination of silver.

With thick film resistors, there is a reaction between the silver in the chips and atmospheric sulfur, leading to the creation of silver sulfide. The formation of silver sulfide causes failure in electronic devices. However, that’s not the case with thin film resistors, as they are designed with a higher level of tolerance for environments with high levels of sulfur. This is why they are the better option for use in electronics and applications where there’s high exposure to outdoor conditions.

Key Market Players

As mentioned earlier, there is a high level of competition in the thin-film resistor market, and some of the big names within the industry are Ralec Electronics, Ta-I Technology, Ever Ohms, Uniohm, KOA, Cyntec, Susumu, Yageo, Bourns, Samsung Electro-Mechanics, and TE Connectivity.

Currently, one of the leading names in the thin-film resistor market is Vishay, and this is because they offer a wide range of products and have a strong global presence. The company has maintained an impressive level of growth with the introduction of advanced products and technologies. KOA is also a key player in the market, and they are widely recognized for customer satisfaction and high-quality products.

When it comes to the size of the market, the market projection is that the growth will reach billions in USD by 2025, which is impressive. Also, the rise of the Internet of Things and technological advancements further boost the growth in the market.

Conclusion

Thin film resistors offer many amazing benefits when used in electronic components, and their integration in passive devices is set to drive the markets for the next couple of years. The main drivers of the market are moisture resistance, volumetric efficiency, precise performance, and sulfur resistance of the components.

There are also different types of thin film resistors, nickel chromium and tantalum nitride being the two main options. Today, these resistors are widely used for different applications, including in medical equipment, defense, oil and gas electronics, telecommunication, transportation and automotive, DC/DC converters, and the power sector as a whole.
