AVX claims to offer the first space-level X7R MLCCs
AVX provides components and interconnect, sensor, control, and antenna devices and believes it is the first to offer space-level, X7R base metal electrode (BME) MLCCs with M and T reliability levels approved to the Defense Logistics Agency’s (DLA’s) MIL-PRF-32535 specification.
The MLCCs exhibit high CV capabilities, reported to be superior to those of precious metal electrode (PME) MLCCs, which have long been the standard for the global aerospace industry. AVX’s space-level, X7R BME MLCCs deliver a 39-fold increase in capacitance compared to standard, 100V, 1812, MIL-PRF-123 and MIL-PRF-55681 MLCCs. The MLCCs enable board space, weight, and component count reductions, while being able to meet stringent DLA requirements for high-reliability performance in space applications.
The series also features AVX’s patented Flexiterm termination technology, which allows for more board flexure than standard terminations, to protect against thermal and mechanical stresses both during assembly and throughout component lifetimes and enabling the safe, reliable employment of large case sizes.
There are seven cases sizes available in the series which is tested to the DLA’s MIL-PRF-32535 specifications. Case sizes span 0402–2220 and the MLCCs are rated for 16 to 100V and 2.2nF to 22-microF.
Target applications include I/O filtering and bulk storage in the switch mode power supplies (SMPS) within space and satellite communications and launchers, military aircraft, and defence, weapons, and radar systems.
The X7R BME technology is approved by NASA (S-311-P-838), the European Space Agency (ESCC 3009/041), and the Defense Logistics Agency (MIL-PRF-32535).
Michael Conway, product marketing manager at AVX, said: “Our MIL-PRF-32535 X7R BME MLCCs feature high-capacitance packages that deliver significant PCB space and weight savings, which are especially critical in the space industry. For example, customers can downsize from an existing CDR34/1812 case size to a M3253504/0805 case size and still achieve a 100V, 56nF rating.”
The series ships with standard high-reliability lead-times, and each production lot comes with the appropriate data package for M and T reliability levels, with A and B sub-groups as required.
