As a leading manufacturer of high-end passive components and connectors, AVX has expanded its voltage and capacitance range for its MIL-PRF-49470- compliant switching power supply stacked multilayer ceramic capacitors , adding to the original 50-500V range. 25V capacitor . The new 25V SMPS capacitors have standard MIL-PRF-49470 B-rated reliability, but the same components with T-level reliability for space applications are being tested.

"At present, AVX 's MIL-PRF-49470 QPL at 25V is the only listed supplier. Therefore, the expansion of the SMPS series will provide engineers with a solution that is in urgent need of lower voltage capacitors by adopting proven technology. Designed to require high reliability performance in demanding environments," said Dan Shields, North American product manager for AVX .

AVX's MIL-PRF-49470 SMPS capacitors are designed for high current, high power and high temperature applications. The capacitor has ultra-low ESR and ESL and can withstand temperatures ranging from -55°C to +125°C. The SMPS series is mainly used for input/output filters in high-power and high-voltage power supplies, and is a bus filter and DC damper for high-power inverters. The series is also suitable for DC/DC converters, conventional and switched power supplies, aerospace instrument panels, various hybrid and military applications.

AVX's SMPS series capacitors are available in 6 package sizes and a variety of via and surface mount leads to provide both effective mechanical decoupling of ceramic chips from the board and for board bending, vibration, and temperature cycling in a wide range of applications. Reduce stress. The lead frame is attached to the chip using high temperature soldering, so there is no risk of reflow soldering when the board is assembled. The SMPS series of capacitors are available in unpackaged (MIL-PRF-49470/1) and packaged (MIL-PRF-49470/2) packaging technologies, providing engineers with enhanced reliability and durability options.

AVX's MIL-PRF-49470 compliant SMPS series capacitance range is as follows: 25V = 1.5–390μF, 50V = 1–270μF, 100V = 0.68–180μF, 200V = 0.47–120μF and 500V = 0.15–39μF. Due to the many options of the SMPS series, all components are priced as requested. The delivery period is 11-14 weeks.
