Syfer’s E07 range of high current 3 terminal EMI chip filters has been extended to include a 3A device. Suitable for use on DC lines on PCB”s, these filters have been designed to reduce electromagnetic interference (EMI) emanating from high speed signal lines and IC’s preventing the propagation of high frequency noise along power lines.
Lower ground path inductance is offered as a result of the dc current being fed through the chip giving a shorter connection to ground. According to Syfer PCB designers will find that a significantly improved high frequency filtering performance is the result.
This new 3A device is available in an 1812 chip size using X7R dielectric. Dependant on voltage rating (25, 50, 100 or 200VDC) the capacitance range is 100nF through to 1.8µF. Aimed at general signal filtering and high speed digital circuitry, these chip filters are particularly suitable for use in the communications and automotive industries.
Available in 0603, 0805, 1206, and 1806 chip sizes, the existing E07 range has also seen a huge increase in the maximum capacitances available across the C0G/NP0 and X7R dielectrics.
All standard versions are fully RoHS compliant. Tin-lead plated devices are optionally 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. Strongly recommended for new designs is the Syfer FlexiCap termination option.
