AVX provides switching power supply (SMPS) capacitors for military and aerospace applications

Filter 18.432M

AVX, a leading manufacturer of passive components and interconnect solutions, has introduced new SMPS capacitors featuring BX technology with X7R dielectrics. These capacitors are available in 25V, unpackaged configurations and are designed for horizontal stacking, making them ideal for use in high-reliability applications. The new component is qualified under T-Class MIL-PRF-49470 standards, further expanding AVX's portfolio of QPL-compliant BX-capable SMPS capacitors.

The expanded lineup now includes high-reliability T-class capacitors rated at 25V, 50V, and 100V—both unpackaged and packaged—for space applications. In addition, AVX offers B-class qualifications, such as DSCC 87106, for 25V, 50V, and 100V components, both packaged and unpackaged, to meet the demands of military, aerospace, and harsh environment applications.

AVX’s B and T grade BX feature SMPS capacitors offer capacitance values ranging from 1.5μF to 390μF, with voltage ratings suitable for operation between -55°C and +125°C. These components are ideal for input/output filtering and high-capacity storage in a wide range of applications, including military defense systems, space and satellite communications, telecommunications infrastructure, DC/DC power converters, high-voltage medical devices, industrial equipment, downhole oil drilling tools, and alternative and hybrid power vehicles.

Patrick Hollenbeck, an application engineer at AVX, stated, “AVX provides the most comprehensive selection of QPL-qualified, high-reliability SMPS capacitors—both packaged and unpackaged—with a broad range of voltage and temperature capabilities. These capacitors are perfectly suited for military, space, and other demanding environments. In fact, AVX’s MIL-PRF-49470 compliant SMPS capacitors are the top choice for input/output filter capacitors in military switching power supplies.”

To support design engineers, AVX offers SpiCalci 8.0 SPICE modeling software. This tool allows users to validate circuits before simulating frequency performance curves and integrating data from specific AVX components. It is compatible with all BX-capable SMPS capacitors that meet MIL-PRF-49470 QPL specifications, helping streamline the design process and ensure optimal performance in critical applications.
