EMI expertise and solutions for real-world applications
Industrial Control & Automation
We do it all from package design and metalworking to EMI filtering to EMC testing. Our EMI filters will satisfy global EMC regulations, improve speed-to-market times, overcome space constraints, and withstand harsh environmental conditions.
Renewable Energy & Infrastructure
Renewable energy stations are often in secluded locations, remotely monitored, and must withstand environmental conditions. Prevent system failure and malfunction by including EMI filtering into the network design process.
Telecom & Data Storage
Telecom and data storage demands system designs that prevent unwanted interference from entering the system and eliminate emissions that contaminate your distributed power. APITech's complete package will save you space, time, and money.
Medical Equipment
Medical equipment requires complete suppression of all EMI, as well as low-leakage, non-magnetic properties to prevent negatively affecting surrounding equipment. We will design and build a high reliability, high performance custom power filter to meet your system and all EN requirements.

50+ Years Experience
Spectrum Control, Inc. (recently known as APITech) has been providing EMI filtering solutions since 1968. We design and manufacture products to suppress or eliminate EMI and offer the industry’s most complete line of filtering products and components. These products help address the requirements of your design while offering the most experienced team of EMI focused engineers in the industry.
Power Line Solutions
Power Line Solutions
We offer a unique ability to understand and address AC and DC power issues ranging from EMC compliance to transient suppression, low voltage cut-off, circuit breakers, redundant power configurations, power distribution, and remote power system access.
Follow the Cord
Understanding how to best filter the AC or DC power entering your system to prevent radiated or conducted EMI can be challenging. Finding a partner capable of developing a custom EMI filter solution that will lower your costs and reduce your time to market can seem unrealistic. Spectrum Control is your answer. Our comprehensive consulting, diagnostic testing, and world class manufacturing will provide you an ideal solution to satisfy global EMC standards while meeting your design/project parameters.
Limiting EMI
Need to limit Electromagnetic Interference
Global regulations limit electromagnetic interference from electronic devices that can easily disrupt wireless radio communications. These regulations have become increasingly important with the proliferation of portable and wireless electronic devices.

EMC Testing
The in-house EMC lab with semi-anechoic chamber at our Fairview manufacturing facility offers our customers a flexible resource to assist in product development by identifying and correcting EMI susceptibility and/or emission problems. The Spectrum Control team will evaluate and tune installed filter performance to find a solution for your unique requirements.
EMI/EMC Basics
Electromagnetic Compatibility (EMC) ensures that multiple electronic devices can function acceptably within the same electromagnetic environment but not interfere with each other's operation. Here we will discuss the basics of EMC standards, test methods, and using mitigation techniques.
Custom EMI Filters
Rarely does an off-the-shelf EMI filter completely satisfy the mechanical, electrical, and power requirements and constraints of a sophisticated OEM design. Whether modifying an existing EMI filter design, working from a "clean sheet: approach or integrating various technologies into a sub-assembly, the resulting custom-built EMI filter will be a product tailored to your project's design, logistic and budgetary requirements.
