Norwich, U.K. Syfer Technology Inc. has extended the capacitance value range for its line of high-voltage, surface-mount multilayer capacitors. Devices in the 500 V to 1.5 kV range are aimed at power supply and dc/dc converter designers in the telecomunications, military and aerospace markets.
Claiming the highest capacitance values in the industry for multilayer ceramic capacitors (MLCCs) at 500 Vdc and higher, the 1206 1.5 kV capacitor, for example, has been increased to 10 nF, up from 2.7 nF. The 1812 1 kV part has been extended from 56 nF to 100 nF. Many devices offer double the capacitance of earlier versions, Syfer said
Smaller case sizes are also available. For example, a 1-kV/1-nF capacitor, previously offered in a 1206 package, is now available in the 0805 case size, and a 1-kV/10 nF part, previously available in a 1812 footprint, is now offered in a 1206 package.
For added reliability, Syfer offers its FlexiCap polymer termination option as an alternative to a standard-plated termination to accommodate a greater degree of board flex. Devices meet RoHS standards with lead-free terminations. Versions with tin-lead contacts can be supplied.
Pricing: Starts at 4 cents each.
Availability: Immediately in sample packs or standard six-week delivery for production volumes.
