MAGNETICS RF POWER

Your Trusted Partner in Innovation

OUR TWO CORE TECHNOLOGIES

Technologies that Deliver

Custom-built for high-power systems, our magnetics and filters are engineered to perform where it counts. View Our Capabilities

Magnetics

WCM specializes in magnetics that perform in high-power systems at frequencies from 100 kHz to 20 MHz. We design custom inductors and transformers in-house—built to meet your specs and last for decades.

RF Filters

WCM RF filters are tuned to specific frequencies and built to block RF energy in high-power systems. They support clean power delivery, protect sensitive electronics, and are especially well-suited for dry etch tools or any application that relies on MHz energy.

WORKING WITH US

Your Partner from Inquiry to Delivery

Our sales, operations and engineering teams partner with you from inquiry through delivery. We have recently doubled our R&D space and added a fully dedicated assembly and test facility. The expansion provided more space for new product prototyping and first article manufacturing. Our manufacturing engineers optimize transfer to production. WCM’s Stockton location offers prototyping services and mid-scale production; high volume production is available at our Tecate, Mexico facility.

25 years ago we started as a build to spec company and still provide this service. Our approach is to understand your application in order to design improvements that may increase performance, reduce size, and/or improve manufacturability. We focus on the performance requirements of a single component to support to the overall success of your projects.

Our core business is design and build. We use the latest technologies and, more often than not, we exceed the initial performance criteria. Many of our customers have long product development cycles and we can pace alongside as projects go to market.

West Coast Magnetics products are engineered and built for maximum performance and our manufacturing process includes rigorous QC to ensure we deliver consistency. We understand the parameters that can affect the functional implementation of components into assemblies. To maximize the performance of your WCM designed and manufactured component, we test and tune before delivery. Let us build out your complete system to maximize performance and reduce variability.

WCM engineers work directly with each customer, designing to their specific needs. By understanding your application we will design performance and manufacturability into each product.

A centerpiece of our process is the design of prototypes that allow customers to test specifications and functional performance. First article builds are made by a specialized, dedicated team that works alongside the manufacturing engineers.

Manufacturing engineering ensures that your design can be built at low quantities and scale as your needs grow. We can support you from prototype up to 50,000 units per month.
