New dual and triple circuit power line electronic filters from Fil-Coil meet the requirements of MIL-F-15733. These dual and triple units run at operating temperatures or -550 degree C to +850 degrees C. Voltage ratings are 115 VAC, 400 VDC, 0 – 400 Hz. With minimum insertion loss characteristics, these MIL-F-15733/75 filters eliminate noise and interference to achieve … [Read more...]
E-Field Antenna Provides Strong Fields for Radiated Susceptibility Testing
The EFG-3 E-field generating antenna from Instruments for Industry (IFI) generates strong electric field intensities for use in radiated susceptibility test systems. A conventional 50-ohm termination of appropriate handling capability allows for the dissipation of any unused power. Consequently, the EFG-3 can handle up to 1000 watts of continuous power. The efficient … [Read more...]
Oxley & Turbo Power Systems Partner to Produce Filtered Connector
Filtered connectors manufactured by Oxley Developments Company Ltdwill soon be flying high on a new commercial aircraft, thanks to aneffective partnership with Turbo Power Systems (TPS).TPS supply the rack-mounted liquid-cooled controller for the aircraft’sjettison fuel pump and required a high performance filtered connector thatwould not only remove electromagnetic … [Read more...]
University of St. Andrews Researchers Use Ferrites to Create Faraday Rotators
An important component in many microwave and mm-wave systems is the isolator or circulator. University of St. Andrews researchers use permanently magnetized ferrite materials to construct quasi optical Faraday rotators (QOFRs) which can be used to make both isolators and circulators. These devices have very high performance and are a key enabling technology for many mm-wave … [Read more...]
Utilizing Overlooked Characteristics of Ferrites for Improved Printed Circuit Board EMI Suppression
ABSTRACT While nickel-zinc composition soft ferrites are routinely used for PCB EMI suppression, the consequences of DC and low frequency AC bias on a device's high frequency impedance has not been widely discussed in the EMC and magnetic component literature. Virtually all EMI suppression applications in DC and AC power filter circuits place two-terminal ferrites under … [Read more...]
Navy Plans to Buy EMI Shielded Cabinets
The Naval Surface Warfare Center, Panama City Division intends to purchase a number of EMI shielded, shock qualified equipment cabinets with two independent 235 CFM cooling fans, mounted in the top rear of the cabinet with the intake in the bottom. The cabinets will require EMI air filters on the intake and outflow. The cabinets must be certified to MIL-STD-461E, shipboard … [Read more...]
New Power Quality Filters Calm the Harmonic Waves
The ECOSine™ line of filters from Schaffner has been launched with a notice that the era of bulky passive harmonic mitigation products is over thanks to superior filter topology and advanced temperature management. With a significant reduction in total harmonic current distortion (THID) toonline. … [Read more...]
Filtered Connectors Provide EMI or ESD Protection for USB
A new series of connectors from Spectrum Control incorporates EMI or ESD protection in an industry standard USB package. These connectors satisfy the requirements of the USB 2.0 spec, which calls for EMI and ESD protection according to industry specifications. Locating the EMI or ESD protection in the connector frees up increasingly precious PCB real estate. These devices are … [Read more...]
Active Filter Protects DC-DC Converters in Harsh Electrical Environments.
The DSF500 from XP Power is a 500-W active filter unit for use in harsh electrical environments. It has been crafted to protect DC-DC converters from the surges, spikes, and ripples that are typically found within the electrical system of any military platform—such as aircraft or vehicles. This filter complies with MIL-STD 1275A-D without the incorporation of any additional … [Read more...]
Indian Plant to Produce Soft Ferrites
DCW (Drangadhra Chemical Works) is now installing a facility for the manufacture of ferrite grade iron oxide from the effluent of the ilmenite plant. The quality of the iron oxide will enable it to be used in the manufacture of soft ferrites, which have wide applications in the electronics industry. The technology employed is the Solvent extraction process, which ensures a high … [Read more...]
