SMALL RC FILTER FOR USB INTERFACE SWPIUSB Replacement for Panasonic EZADLU Smallest RC filter for USB interface 2 PI RC Filter circuits in a chip Saving space and cost Superior mountability with concave terminal Firm solder joint Self alignement of placement at reflow soldering Information and amusement equipment containing USB interface The SWPIUSB is a 2 channel EMI PI filter array offering a combination of 2 low-pass PI filter channels to reduce EMI/RFI emissions on USB interface port. Each EMI/RFI channel integrates a high quality pi-style filter (R-R-C) which provides greater than xxdB attenuation in the 800-2700 MHz range. These pi-style filters support bidirectional filtering, controlling EMI both to and from a data port connector. The SWPIUSB is particularly well suited for portable electronics (e.g., cellular telephones, PDAs, notebook computers, games, flash memory modules) 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 are ideal for high reliability hybrid and multi chip module applications.

SHORT PRODUCT APPLICATION NOTE
The SWPIUSB is a 2 channel EMI PI filter array offering a combination of 2 low-pass PI filter channels to reduce EMI/RFI emissions on USB interface port. Each EMI/RFI channel integrates a high quality pi-style filter (R-R-C) which provides greater than xxdB attenuation in the 800-2700 MHz range.

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.
