Syfer is responding specifically to demand from the telecoms, power supply and dc/dc converter markets. “Much of this equipment has to meet stringent high voltage tests, often way beyond their normal operating voltages,” explained Howard Ingleson, Managing Director of Syfer. “Designers are looking for the most cost effective solutions, and these range extensions allow the designer greater choice of working voltages,” he added.
The new additions are designed to provide lower cost, and potentially smaller case size alternatives to the standard 2kV and 3kV parts, while ensuring equipment passes the necessary high voltage tests.
Available in both C0G and X7R dielectrics, the 1.2kV and 1.5kV versions start with 1206 packaged parts. Typically, package size is at least one size smaller than the equivalent capacitance, for example 1812 X7R 10nF is available in 1210 at 1.2KV. Alternatively, designers get greater capacitance in the same size package, for example 1808 X7R 2KV 4.7nF is available with 10nF at 1.2KV.
