New X2 EMI Suppression Film Capacitors Feature Increased Voltage Rating
The new MKP 339 X2, MKP 338 2 X2, and MKP 336 2 X2 from Vishay Intertechnology are X2 EMI suppression film capacitors with an increased maximum mains voltage of 310 VAC and a wide range of lead pitches and capacitance values. These devices differ from conventional EMI suppression capacitors that offer a typical voltage range of 275 VAC to 305 VAC. They offer designers an … [Read more...]
Enhanced Test System Targets Emissions Testing from 9 kHz to 30 MHz
A newly released version of GAUSS Instruments’ “TDEMI” test systems carries out emissions testing from 9 kHz to 30 MHz. The original version, released earlier this year, handled the frequency range of 150 kHz to 1 GHz. With the new “TDEMI30M” a quasi-peak measurement in Band A or Band B can take as little as 12 seconds. The “TDEMI” measurement system from GAUSS Instruments … [Read more...]
Emission Measurement System Features Real-Time Analysis
The “TDEMI” measurement system from GAUSS Instruments carries out emission measurements in the time domain, and features EMI receiver emulation using an FFT-based bank of filters. With real-time analysis, the signal is parallel-processed continuously over a wide frequency band and is then analyzed using the quasi-peak detector. A special mode enables real-time analysis in peak, … [Read more...]
Op Amps Feature Integrated EMI Filters
The LMV83x Series of operational amplifiers from National Semiconductor has integrated EMI filters that maintain the accuracy of analog systems by reducing the effects of RF (radio frequency) interference. They are reported to have an EMI rejection ratio (EMIRR) of 120 dB. The LMV831 single, the LMV832 dual, and the LMV834 quad op amps feature CMOS inputs, a maximum inset … [Read more...]
Online Drawing Feature Aids Purchasers of Board-Level Shields
A configurable PDF Drawing feature offered by Tech-Etch aids purchasers of both single-piece and two-piece board level shields. Users simply go to the Tech-Etch website. The first step is choosing either through-hole mounting with pins or standard surface mounting. Depending on the user’s choice, seam options and required dimensions are then filled in. Next, the metal material … [Read more...]
Aluminum SMD Capacitors Target Consumer and Industrial Applications
A new line of SMD electrolytic capacitors from EPCOS covers a capacitance range from 0.1 µF to 1500 µF and are suited for voltages from 4 VDC to 100 VDC. Versions are available for temperature ranges from -40 to +85 degrees C. Depending on the CV value, the case sizes vary between 4 mm x 5.4 mm and 10 mm x 10 mm (d x l). The B41142* series with ESR values from a minimum of 0.8 … [Read more...]
Embedded FRAM-LSI Counteracts EMI in Mobile Phones and Other Applications
The MB88R157 from Fujitsu Microelectronics Limited (FML) is an addition to its existing line of spread-spectrum clock generators used to counteract EMI on high-frequency clock signals. This device includes an embedded FRAM (ferroelectric random access memory), which features fast rewriting speed and can vary its frequency output over a range of 1 MHz to 134 MHz while mounted on … [Read more...]
