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...]
LED Driver for Automotive Applications Minimizes EMI
Linear Technology has announced the LT3932, a monolithic, synchronous, step-down DC-DC converter with internal 36V, 2A power switches and an internal PWM generator. Its fixed frequency, peak current mode control accurately regulates current within ±1.5% for strings of up to 2A LEDs. Its integrated PWM generator offers a 128:1 dimming ratio. The device’s 3.6V to 36V input … [Read more...]
Top Three EMI and Power Integrity Problems with On-Board DC-DC Converters and LDO Regulators
Co-authored by: Kenneth Wyatt and Steve Sandler INTRODUCTION Modern devices are continuing a long-term trend of squeezing more electronics into smaller packages, while also increasing system performance, data rates and operating efficiency. Higher efficiencies are often achieved by implementing faster silicon MOSFETs or even faster eGaN FETs while size is reduced by … [Read more...]
Ultra Low Noise Pluggable PSUs
Originally developed as a custom solution for highly sensitive electronic measuring equipment designed to capture experimental ring accelerator data, the new Eplax 3U 7HP 19" pluggable PSU with output noise levels below 4 mV p-p is now available as a standard product through Verotec Inc. for any high sensitivity application where ripples and spikes on the output voltage must be … [Read more...]
New Line of Filter Capacitors for Power Supplies
TDK Corporation has significantly extended its range of EPCOS single-phase power capacitors for industrial electronics. The capacitors of series B32370* through B32374* are designed for rated AC voltages of between 250 VRMS and 600 VRMS, cover a capacitance range from 5 µF to 600 µF, and feature a maximum current capability of between 15 A and 60 A, depending on the type. The … [Read more...]
