High-Impedance Chip Beads with Lowest DC Resistance
TDK Corporation announced the development of the MMZ0402EUC series of chip beads, with the lowest DC resistance for a chip bead its size. The two new types with their respective impedance values of 150 Ω and 180 Ω at 100 MHz, feature DC resistance values of only 0.62 Ω and 0.69 Ω. This results in a significant reduction in power losses, while at the same time providing … [Read more...]

New Single Layer Capacitors Launched
Recently launched by DLI is the V Series, Single Layer Capacitor (SLC). This series was designed to provide higher capacitance in a smaller footprint. The wire bondable range is ideal for power applications where excellent high frequency response is a prerequisite. This, together with the small footprint of just 0.03”/0.77mm square, allow for high density mounting. Excellent … [Read more...]
Simulating EM Shielding for Aeronautical Applications
The airframe of an aircraft can provide some measure of shielding against high-intensity radiated fields (HIRF), but this is compromised by doors, windows, seams, access panels and components interfaced to the airframe such as antennas used for communication and navigation. Composite materials are increasingly used in aeronautical applications due to their relatively light … [Read more...]
Choosing and Using Silicon Protection Devices
Introduction Correctly choosing an external (off chip) Transient Voltage Suppressor (TVS) is not as simple as it once was. Integrated Circuit (IC) feature size is shrinking (Figure 1) and more and more inputs are being exposed to the outside world. Portable consumer devices are everywhere and have more functions in smaller and smaller sizes, necessitating smaller and smaller … [Read more...]
New Nanocrystalline Common Mode Chokes
ITG Electronics, a leading manufacturer of inductors and transformers in business since 1963, now offers a range of Nanocrystalline Common Mode Chokes which deliver higher power ratings in a small size. Nanocrystalline material gets its name from its production process. A stream of molten metal is rapidly cooled and locks in the amorphous high energy structure. The resulting … [Read more...]
