TDK Launches Thin-Film Common Mode Filter

 

TDK Corporation announced that it has developed a wide-band thin-film common mode filter for EMI suppression on DisplayPort interfaces.  The new product which carries the designation TCM1210U-500-2P will be available beginning July 2008. The new filter measures 1.25 mm (L) x 1.0 mm (W) x 0.6 mm (T) in size and is designed specifically to suppress noise on DisplayPort … [Read more...]

Instrumentation Amplifier Includes Filters to Reduce RF Interference

 

The new INA333 is a is a zero-drift instrumentation amplifier from Texas Instruments with input bias current of 200 pA and quiescent current of 75 µA. Offset voltage is 25 µV, and offset drift is 0.1 µV/°C. The INA333 yields an input voltage noise of 50 nV/rt-Hz with a proprietary switched capacitor notch filter. The MSOP-8-packaged amplifier has 3 op-amp architecture and … [Read more...]

Extended Aluminum Capacitor Line Provides Z as Low as 60 mΩ

 

A new CRZ device from Vishay Intertechnology is the latest edition to the 150 CRZ series of surface mount aluminum capacitors. The 150 CRZ devices are now available in five case sizes, ranging from 8 mm x 8 mm x 10 mm to the larger 12.5 mm x 12.5 mm x 16 mm. The capacitors offer impedance as low as 60 mΩ at 100 kHz, a high rated ripple current of 1007 mA at +150 degrees C. and … [Read more...]

Signal Analyzer Offers an Analysis Bandwidth of 40 MHz

 

The new R&S® FSV signal analyzer offers an analysis bandwidth of 40 MHz and can, thus, cover a wide range of wireless standards—from 3GPP LTE up to WLAN 802.11n.  With 1000 sweeps/s in remote control mode it allows for higher throughputs in product production. It integrates easily into existing production lines because it is compatible with earlier generations of Rohde … [Read more...]

Multifunctional Test System Enables Numerous Applications

 

The NSF 4070 from Teseq is a multi-functional EMC immunity test system. Its frequency range of 9 kHz to 1 GHz and a modular set-up using internal or external amplifiers enable a large variety of applications including tests according to IEC 61000-4-6, various BCI applications as well as signal generator and power meter test systems as per IEC 61000-4-3, IEC 61000-4-20, and IEC … [Read more...]

Arc Spray Technology Improves EMC Shielding

 

With the introduction of a fully automated, robotic coating production plant, HARTING can plate a variety of different plastic housings. The innovative process utilizes arc spray technology with zinc as the coating metal. Zinc is a highly conductive material that, when applied with high layer thickness through the coating process, provides a performance similar to that of full … [Read more...]

Electrical Noise Shielding Jacket Protects Data Cables

 

Swift-Lock from Swift Textile Metalizing (STM) LLC is used to close an electrical shielding jacket that covers each data cable and prevents the manufacturing equipment floor from interfering with computers and bar code readers used on the factory floor. Swift-Lock is a reusable electrically conductive hook-and-loop for grounding static electricity and closing shielding … [Read more...]

EMC Filter Series Targets Applications with Long Motor Leads

 

EPCOS has extended its 3-line EMC filter offerings with a high-performance series for frequency converters.  Its attenuation properties of the B84143D*R127 series offer decisive advantages especially with long motor leads. Cable-based measurements of commercial frequency converters showed that the EN 55011 limits were observed for class A up to 300 m and class B up to 200 m as … [Read more...]
