High capacitance, surface mount chip capacitors save space and cost

The range of high voltage, high capacitance, surface mount chip capacitors from Syfer Technology has just been extended with a number of new additions. Now one of the most extensive families available, Syfer’s high voltage capacitors span the range from 16V to 6kV, with capacitance ranges from 0.47pF to 15µF. The latest introductions, at 1.2kV, 1.5kV and 2.5kV, slot neatly into the series, giving engineers a broader choice of devices with which to optimise their designs for cost and space, while ensuring they meet high voltage tests for transients and spikes.

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.
