Every engineering choice has trade-offs. As a general rule of thumb, most off-the-shelf coil components have fast lead times, are more cost-effective, and are available from multiple sources. But custom products offer optimal performance for specialized applications and are tailored for your specific operating environment. Many critical applications, such as medical imaging and scanning, semiconductor manufacturing, and satellite production, depend on optimized design performance of their electromagnetic assemblies.
Choosing the right coil is an important decision that must consider finances, long-term product success, and competitiveness in your industry. For electromagnetic assemblies with certain application constraints, custom coils are the best option.
Main Considerations
Every production project will have unique concerns that take precedence. Here are four key factors when specifying a coil for your project.
Cost
Cost is a major consideration for every project. Off-the-shelf coils are generally most affordable upfront because they have already completed laboratory and regulatory testing for product safety and have wide availability across multiple manufacturers.
However, due to their design limitations, off-the-shelf coils in highly specialized products can lead to suboptimal performance, which can mean higher replacement costs over the product’s entire service life or even product failure. In fact, if the magnetic coil in your application is so critical that achieving less than optimal performance means product failure, then a custom coil is your only option.
Performance Requirements
Off-the-shelf coils may not align with particular design and performance needs, leading to poor or inconsistent performance and frequent replacements. If you have unique performance requirements, a custom coil manufacturer can work with you to create precision-engineered solutions that provide the right power, connections, mounting, thermal management, and mechanical properties within the given space constraints.
Operating Environment
Different electromagnetic assemblies are intended for different environments, each with its own potential hazards that can shorten the functional lifespan of a coil. Off-the-shelf coils can be designed for particular uses, but custom coils better serve highly specific, regulated applications with harsh operating environments, such as extreme cold or heat, radiofrequency interference (RFI), and more.
Lead Time
Since off-the-shelf coils don’t have prototyping and testing periods, their lead times are much faster than custom coils. However, if you partner with an experienced custom coils provider, they can streamline these processes as much as possible while delivering a coil that’s a perfect fit for your application.
When to Choose Custom Over Off-the-Shelf Coils
Custom coils should be chosen instead of off-the-shelf coils in these situations:
- When off-the-shelf coils don’t meet your application parameters
- When the magnetic component in your application is so critical that achieving optimal performance makes the difference between failure and success
- When your products need to handle critical operations, such as environmental extremes
How to Find a Quality Custom Manufacturer
It’s important to choose a high-quality custom manufacturer that offers full-service operations from design to prototyping to production.
Design and Engineering
Your custom coil manufacturer should specialize in coil design and engineering, including design for manufacturability (DFM) analysis. Custom Coils provides design support and engineering expertise to create designs that exactly align with project parameters and tight tolerances.
Prototyping and Development
