ProTek Devices Introduces EMI Filter/ESD Protection Device for Portable Electronics


TEMPE, Ariz., August 11, 2005 ­ ProTek Devices has introduced the EM8D-100L, a 16-pin DFN package, 8-line low pass filter array with integrated TVS diodes. The EM8D-100L is designed to suppress unwanted EMI/RFI signals and provide ESD protection for high-speed data interfaces such as color LCD displays, camera imagers in mobile phones and PDAs.

With a desired cutoff frequency of 150MHz, the EM8D-100L provides good EMI/RFI attenuation, which is better than 25dB in the 800MHz - 3GHz bandwidth. This blocks the RF noises from GSM, DCS, or Bluetooth, which affect the baseband chipset and other blocks. Coupled the integrated TVS diodes, the EM8D-100L meets the immunity test standard IEC 61000-4-2 at all levels, providing excellent ESD protection.

In the standby mode, the integrated TVS filter has a very low leakage current (less than 100µA) ­an essential feature for battery powered handheld devices. In addition, the low profile durable 16-pin DFN package is useful in many applications.

The EM8D-100L is now available for sample quantities on tape and reel. Pricing is $0.56 each in 12,000 piece quantities. For technical information, contact support@protekdevices.com, Phone: 602-431-8101, Fax: 602-431-2288.
