EMI filter arrays with integrated ESD protection diodes

22 March 2006 Circuit & System Protection

Vishay has released six new EMI filter arrays with integrated ESD protection diodes. Offered in ultra-small leadless, plastic packages, the devices provide both EMI filtering and ESD protection for data lines in space-critical mobile applications.

The new VEMI arrays are available in compact LLP75-6A, LLP75-7A, LLP70-9A, and FlipChip (BGA) packages and provided, respectively, in two-, three-, four-, and six-channel configurations. Designed for cost-effective use in high-volume computing, communications, and consumer products, the arrays are intended to provide I/O protection in mobile and smartphones, laptop computers, PDAs, MP3 players, digital still cameras, modems, and mobile gaming systems.

Delivering high-quality filtering, they are capable of attenuating unwanted signals by more than 30 dB over the 900 MHz up to 2,3 GHz frequency range, with low line resistance values from 30-100 Ω. Low leakage current and capacitance help to prolong battery life. All six arrays provide transient protection for data lines as per IEC 6100042 (ESD) at 30 kV (air and contact discharge) and IEC 6100045 (lightning) from 4 A to 5 A (tp = 8/20 μs). They also are RoHS and WEEE compliant.
