Electronic devices are becoming more complex, and few people know more than the barest details about the components they use. Many resources discuss microprocessors, semiconductors, and transistors; however, few explain the functions of the magnetic components vital to these devices. Inductors, transformers, and other components are often considered much lower-tech than other ones. Despite their obscure status, these components are advanced in construction and design. Magnetic elements typically share many design traits, like a foil or wire that’s wound onto a bobbin, core, or mandrel. They can have or lack layers of insulation. Simpler components can occur from automation in high volumes. But, most inductors and transformers are complex and need significant labor.
Many magnetic components are custom-designed to fit unique physical and electrical specifications because different applications need distinct parts to be safe and effective. Some inductors and transformers are subject to special safety certifications dependent on their application. Transformer designs always incorporate safe margins. Engineers should be equipped to process acceptance tests and simulate transformers under operating conditions. To ensure that the component won’t overheat during actual use or in the case of short circuits on windings, the client will need to agree to specific type tests, like surge tests. The operating temperature will determine the insulation class used in the component. Typical temperature ratings include B (130°C), F (155°C), and H (180°C). Ambient temperatures also factor into insulation types.
Types of Industrial Magnetic Components
Syrma: Magnetics Manufacturer
We provide a full range of custom magnetic assemblies and magnetic products. Our advanced and scalable production resources enable us to meet your cost and performance specifications. Magnetic components (chokes, inductors, and transformers) are key automotive, computers, consumer electronics, defense, home appliances, and lighting. Our Ferrite core transformers, both through-hole and SMD type, have up to 500 watts with a frequency of up to 300 kHz. Our inductors operate over a wide range of frequencies, input voltages, and inductance values. Our chokes protect circuits from high-frequency alternating current and allow for low-frequency direct current.
Our engineering team draws upon 20+ years of experience at the forefront of analog design and manufacturing to ensure a streamlined end-to-end product cycle, from prototyping and testing through high-volume production. Our localized supply-chain ecosystem enables us to seek lower costs among trusted suppliers constantly. Core materials used in magnetics include cobalt alloys, ferrite, metallic glass, nickel alloys, and silicon iron. Construction of coil devices varies widely in the number of turns of a magnet, tefzel, and litz wires. Most windings are automatically wound on thermoplastic or thermoset bobbins, which offer excellent ground insulation, the most effective use of window area, and the greatest amount of control for through-hole or surface mounting.
Backed by 40 Years of Expertise
We contribute our 40 years of design and manufacturing expertise spanning multiple diverse markets. We look forward to discussing how we can deliver world-class products for OEMs across the globe.
