ITG Electronics, a leading manufacturer of inductors and transformers in business since 1963, now offers a range common footprints as well as custom flat wire inductors for high power density and high frequency switching. As the name suggests, flat wire inductors utilize a flattened, rectangular cross section, copper wire instead of a traditional, circular cross section, … [Read more...]
Expanded EMC Cable Fittings
LUTZE Inc. expands its industrial cable fitting offering and introduces large diameter EMC (Electro Magnetic Compatibility) fittings to include sizes for large diameter cables up to 500MCM (75mm OD). These NPT and metric thread fittings provide effective strain relief and 360° shield termination. They use the same clamp style shield termination method as our smaller EMC … [Read more...]
HDMI Cables and EMI
As more consumer and commercial products are introduced with High-Definition Multimedia Interface (HDMI) cable connections, the resulting EMI issues related to HDMI cable emissions have continued to be problematic for product designers and EMC engineers. It is very common to have one, or more, added HDMI cables cause a product to fail the radiated emissions (RE) test. The … [Read more...]

ESD Effects of Digital ICs
One issue I see fairly often with unshielded consumer or commercial products is CPU resets during periods of immunity testing, such as during electrostatic discharge (ESD) testing. Untreated, this can lead to field failures and associated customer satisfaction issues. The remedy is usually quite simple and IC manufacturers even mention the solution, but it’s usually buried … [Read more...]
Gaps In Return Planes – Bad News for EMI
Currently, there is an ongoing discussion among SI and EMC engineers on the fine points of PC board design for best signal integrity and EMI performance. Among the topics it seems designing in gaps or slits in ground return planes always comes up. Gaps can also occur mistakenly due to the addition of some connectors or other object that creates gaps in the copper. In fact, … [Read more...]
Measuring Cable Resonances With A Comb Generator
(October 28, 2016) Cables are one of the key metallic structures on a product that can act as an antenna and couple energy, causing radiated emissions and possible compliance test failures. This has been discussed extensively in the literature on product design for EMI compliance. In many cases, they can resonate at their half-wave frequency and actually amplify any harmonic … [Read more...]
