ProTek Devices Introduces EMI Filter/ESD Protection Device
EM4D-100L is a 2 mm square, 8-pin DFN package, 4-line low pass filter array with integrated TVS diodes. 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 150 MHz, provides EMI/RFI attenuation better than 35 dB in the 800 MHz - 3GHz bandwidth. This blocks RF noises from GSM, DCS or Bluetooth, which affect the baseband chipset and other blocks. Meets the immunity test standard IEC 61000-4-2 at all levels, providing ESD protection.
In standby mode, integrated TVS filter has a very low leakage current (less than 100 µA) - an essential feature for battery powered handheld devices. In addition, the low profile durable 8-pin DFN package is useful in many applications.
