Sinusoidal Wave Filter Overcomes Interference Problems to Reduce Cable Costs

 

REO-USA has introduced the 400V three-line CNW933 sinusoidal filter range as an equally robust yet more cost effective solution to shielded cables. The cost of cables is rising in manufacturing as the result of the need for lengthy shielded cable to tackle attenuation and electromagnetic compatibility (EMC) issues. Compounded by increasing commodity prices, this is leading … [Read more...]

Medical-Grade Heat-Shrink Tubing for Cable Shielding

 

Methode Electronics, Inc. has released new medical grade shrinkMate™ heat-shrink tubing, which provides easy-to-apply shielding at the cable-to-connector joint, a common point of leakage. Made of clear medical grade polyester, the lightweight tubing shrinks when heat is applied to firm a conductive seal around an object, providing EMI, RFI and ESD shielding without the use of … [Read more...]

Double-Duty Electrical Cables Can Store Energy

 

Scientists at the University of Central Florida have developed a way to both transmit and store electricity in a single lightweight copper wire. Jayan Thomas, a professor at the University of Central Florida, and Ph.D student Zenan Yu created a supercapacitor on the outside of a copper wire as a means to store energy while allowing electricity to continue passing through the … [Read more...]

RF Coaxial Cable Assemblies Up to 50 GHz Suited for High-Frequency Interconnects

 

Crystek has announced it has extended the frequency range of its high performance RF coaxial cable assemblies to 50 GHz. Ideally suited for high-frequency interconnects in mission-critical applications and microwave laboratories, the new low-loss cable assemblies (P/N series CC2450-MM-150) feature corrosion-resistant 2.4 mm 303 stainless steel connectors and provide RF … [Read more...]

Mitigating Excessive Emissions, 2nd Edition

 

Donald L. Sweeney and Marilyn Sweeney D.L.S. Electronic Systems, Inc. Mitigating Excessive Emissions was originally written in 1988 and presented at the IEEE EMC Symposium in Atlanta Georgia. The concept and paper have been used by the author hundreds, if not thousands, of times to illustrate what he calls “The Barbell Model.” This illustrates, in very simple terms, how … [Read more...]
