AVX Corporation has expanded its Flexiterm series of capacitors by adding a high-voltage MLC chip for applications requiring ratings from 600 V to 3000 V. The capacitor provides high value, low leakage and small size in a rugged package that will not crack under extreme board flexure or temperature damage cycle conditions. The new Flexiterm V+ exhibits low equivalent series resistance at high frequency. It is designed for applications such as snubbers in high-frequency power converters, resonators in switching-mode power supplies and high-voltage coupling/dc blocking.

Because Flexiterm is a soft termination system it allows more than twice the board flexure when compared to standard termination systems. Further enhancing the capabilities of a standard MLCC, it was developed as an additional flexible termination layer added to the component to ensure that electrical integrity is maintained when external forces are applied and to prevent failures in the system due to cracking.

Flexiterm's flexible termination comprises a conductive polymer layer that is then plated with nickel and tin. Resistance to mechanical failure can be attributed to Flexiterm's ability to reduce the transfer of mechanical stress exerted on the component body. Flexiterm V+ is available in case sizes from 1206 to 2220, with voltages ranging from 600 V to 3000 V. The components are also available in a RoHS-compliant, matte-tin finish and also with a tin-lead finish.
