RF Chip Inductor Application Note
Laird Technologies, Inc. has published its newest application note titled “RF Chip Inductor Applications.”The application note explains how RF chip inductors are an integral part of many tuning and filtering circuits. Mainly used in the RF circuits in electronics systems, they reduce or eliminate electromagnetic interference (EMI) noise on the printed circuit board (PCB). The … [Read more...]
Capacitors with Low Insertion Height
TDK-EPC has developed a wide range of EPCOS MKP and MKT film capacitors with low insertion heights. The new capacitors with a lead spacing of 37.5 mm feature insertion heights of only 15 or 19 mm. These components are designed for rated voltages of between 63 and 2000 V DC or 250 to 400 V AC. Their capacitance ranges from 0.1 to 82 µF. Depending on type and technology (MKT or … [Read more...]
IEC Releases Fixed Capacitors Standard for use in Electronic Equipment
IEC 60384-2:2011 applies to fixed capacitors for direct current, with metallized electrodes and polyethylene-terephthalate dielectric for use in electronic equipment. These capacitors may have "self-healing properties" depending on conditions of use. They are primarily intended for applications where the a.c. component is small with respect to the rated voltage. Two performance … [Read more...]
Fliers Refusing to Turn Off Electronics, Study Shows
Despite being warned for decades, fliers are refusing to turn off electronic devices during takeoff and landing. USA Today’s investigation included reviewing “more than 25 papers by electronics experts; presentations; papers, and advisories by government aviation officials in the USA, Canada, and the United Kingdom and Europe” and they surveyed “more than 900 frequent fliers” … [Read more...]
iPad Case Diverts Radiation and Improves 3G
Pong Research has launched the Pong iPad and iPad 2 case, to provide the same antenna technology to tablet users. The Pong case diverts radiation away from the user, reducing the SAR by up to 82 percent of FCC limits. The case also provides enhanced 3G connection performance.Some cases will activate the iPad proximity sensor, which reduces 3G transmission power by 75 percent to … [Read more...]
Electromagnetic Waves Illuminated with Coffee Cans and LEDs
To show how EM is all around us, Dr. Gregory Chavat came up with a presentation using “a coffee can radar system, a couple of LEDs, and long-exposure photography.” His set up included a “radar emitter made out of one coffee can and a second can with a couple of LEDs attached to serve as a tethered receiver antenna.” He moved the receiver around the emitter while taking a long … [Read more...]
Precision High Voltage Modules Include AC, DC Input
Spellman High Voltage Electronics Corporation’s new V6 high precision, cost-effective high voltage modules on a common platform include either AC or DC input, with analog or digital interface (RS232) capabilities. The V6 Series offers output voltages ranging from 500V to 30kV, and incorporates the high precision features of Spellman’s 600 Series (replacing the 602C, 603C, 605C … [Read more...]
