Data I/O Port EMI/RFI PI Filter ESD Protected SWPIESDE1channel of EMI filtering for data ports Pi-style EMI filters in a capacitor-resistor-capacitor (C-R-C) network Greater than 32dB attenuation at 1 GHz ±15kV ESD protection on each channel (IEC 61000-4-2 Level 4, contact discharge) ±30kV ESD protection on each channel (HMB) EMI filtering and ESD protection for both data and I/O ports Wireless Handsets Handheld PCs/PDAs MP3 Players Notebooks Desktop PCs The SWPIESDE is a one to eight channels low-pass filter array that reduces EMI/RFI emissions while at the same time providing ESD protection. It is used on data ports on mobile devices. To reduce EMI/RFI emissions, the SWESDE integrates a pi-style filter (C-R-C) for each channels.Each high quality filter provides greater than 30dB attenuation in the 800-2700 MHz range. These pi-style filters also support bidirectional filtering, controlling EMI both to and from a data port connector. In addition , the SWPIESDE provides a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The input pins are designed and characterized to safely dissipate ESD strike of 15kV, exceeding the maximum requirement of the IEC 61000-4-2 international standard. Using the MIL-STD-883 (Method 3015) specification for Human Body Model (HBM) ESD, the device provides protection for contact discharges to greater than 30kV. The SWPIESDE is particularly well suited for portable electronics (e.g., cellular telephones, PDAs, notebook computers) because of its small package format and low weight. Integrated passive networks are manufactured using advanced thin film technologies including ultra-stable and self passivating Tantalum Nitride resistors, gold interconnect metallization and reliable MNOS capacitors to achieve excellent uniformity, performance and reliability. Thin film resistor technology is the preferred solution for all applications that require low noise, long term stability and excellent performance at very high frequencies. Semiconwell employs proprietary thin film technologies for deposition of a wide range of sheet resistance films from 1W/sq to 10,000 W/sq. All Semiconwell's products are available in die form and are ideal for high reliability hybrid and multi chip module applications. Semiconwell manufactures passive network components, integrated active and passive devices, resistor networks, capacitor networks, schottky and zener diode networks, and npn, pnp transistors arrays that perform the following functions: series and parallel linear and nonlinear GTL, AC, Diode, Thevenin termination networks, precision thin film resistor capacitor networks (RC networks), isolated, bussed resistor networks including zero ohms jumper arrays, voltage divider networks, resistor networks for audio applications, EMI, RFI and ESD zener clamped diodes and transient voltage suppressors networks, EMI/RFI filter networks and clock terminations. Semiconwell's proprietary semiconductor technology, advanced thin films processes, in house assembly and packaging technologies allow manufacturing of flip chip CSP chip scale and MLF molded lead frame surface mount integrated passive networks that include unprecedented large capacitors >1microfarad (1µF) and giga ohms resistors (GW).

SHORT PRODUCT APPLICATION NOTE
The SW2FAFUSB is a multichannel EMI/ESD array offering a combination of four low-pass filter + ESD channels to reduce EMI/RFI emissions on a data port and one to four dedicated ESD-only channels intended specifically for ESD protection on a USB port. Each EMI/RFI channel integrates a high quality pi-style filter (C-R-C) which provides greater than 35dB attenuation in the 800-3000 MHz range. These pi-style filters support bidirectional filtering, controlling EMI both to and from a data port connector. The SW2FAFUSB provides a high-level of ESD protection on all eight channels for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The input pins are designed and characterized to safely dissipate ESD strikes of 15kV Air/8kV Contact, exceeding the maximum requirement of the IEC 61000-4-2 international standard. The SW2FAFUSB is particularly well suited for portable electronics (e.g., cellular telephones, PDAs, notebook computers) because of its small package footprint and low weight.

SEMICONDUCTOR-THIN FILM MANUFACTURING PROCESS DESCRIPTION
Integrated passive networks are manufactured using advanced thin film technologies including ultra -stable and self passivating Tantalum Nitride resistors, gold interconnect metallization and reliable MNOS capacitors to achieve excellent uniformity, performance and reliability. Thin film resistor technology is the preferred solution for all applications that require low noise, long term stability and excellent performance at very high frequencies. Semiconwell employs proprietary thin film technologies for deposition of a wide range of sheet resistance films from 1W/sq to 10,000 W/sq. All Semiconwell's products are available in die form and as KGD, known good die and are ideal for high reliability hybrid and multi chip module applications. Besides thin film resistors, Semiconwell integrates capacitors, Schottky diodes, Zener diodes and transistors. Integrated passive and active networks are manufactured using Semiconwell's in house high reliability semiconductor manufacturing processes. All semiconductor devices employ precision doping via ion implantation, silicon nitride junction passivation, platinum silicided contacts and gold interconnect metallization for best performance and reliability. MNOS capacitors and Tantalum Nitride resistors are easily integrated with Schottky diodes to provide complete standard and custom RCD solutions. In die form, these products are ideal for hybrid and multi chip module applications. In packaged form, these products are the best solution where space and weight are a concern.
