Capacitors block interference

Feeding DC current directly through the E07 chip filters will provide PCB designers with a significantly improved high-frequency filtering performance.

Syfer Technology has released the E07 range of high-current, three-terminal filter chips, which are designed to block electromagnetic interference (EMI) emanating from high speed circuitry and prevent the propagation of high-frequency noise along power lines.

The existing range has seen a huge increase in the maximum capacitance available, as well as in the number of values.

The devices are capable of carrying high currents, up to 2A, making them ideal for installing on the DC power lines on printed circuit boards.

Feeding DC current directly through the E07 chip filters will provide PCB designers with a significantly improved high-frequency filtering performance.

Manufactured at Syfer's state of the art, Norwich, UK facility, the chip filters are available in three versions.

The smallest, 0805 device features a capacitance range from 1 to 47nF with a -1A current rating.

The 1206 version extends the capacitance to 100nF with a 2A current rating.

Finally, the 1806 is available from 22 to 200nF capacitance, also with 2A current ratings.

The operating temperature range is -55 to 85C and the working voltage is either 100 or 50V DC, depending on capacitance value.

Aimed at general signal filtering and high-speed digital circuitry, the chip filters are particularly suitable for use in the automotive and communications industries.

All standard versions are fully RoHS compliant.

Tin-lead plated devices are available for use in high-reliability applications, such as in the space/aerospace industry, where tin whiskers are considered to be a major risk issue.
