Stacked Capacitors Resist Mechanical Stresses

AVX has expanded its switch-mode power supply (SMPS) capacitor series to include a RoHS-compliant version that is suitable for DC/DC converters, hybrid vehicles and medical electronics equipment. The addition of the RoHS Turbocap to this product series increases the global product range. Utilising BME MLCC's, the RoHS Turbocap provides high CV values, low ESR values, high current-carrying capacity and good high-frequency performance.

The rugged devices are also resistant to mechanical stresses incurred during board flexing, vibration or temperature cycling. According to AVX, the Turbocap Series stacked capacitors enable designers to reduce their component count, shrink board space and maintain the benefits of ceramics, such as low ESR/ESL, ability to withstand transients and the ability to handle large amounts of power in an efficient and compact package. The RoHS Turbocap Series capacitors are available in the same X7R dielectric as the standard Turbocap.

The stacked capacitors are suitable for DC/DC converters, hybrid vehicles, military/COTS including power supplies, medical electronics equipment, industrial equipment, telecom and alternate energy applications. The expanded Turbocap Series capacitors are assembled using AVX's industry-proven lead frame technology, which places the ceramic up off the board and dramatically reduces cracking issues, as well as susceptibility to shock and vibrations.
