Product Expansion in BME NP0 MLCCs

KYOCERA AVX has announced an expansion of its MIL-PRF-32535 base metal electrode (BME) NP0 multi-layer ceramic capacitors (MLCCs), now approved by the Defense Logistics Agency (DLA) and listed in its Qualified Products Database (QPD). This updated series introduces new case sizes and a broader range of capacitance values, addressing the increasing demands of the aerospace and defense sectors.

These BME NP0 MLCCs, benefitting from over 30 years of research and development, utilize advanced technology to deliver superior capacitance (higher-CV capabilities) compared to traditional precious metal electrode (PME) MLCCs. By bridging the gap between commercial products and military specifications, these capacitors ensure compliance with “M” and “T” reliability levels, offering design engineers notable advantages in their projects.

The newly available capacitor options include small, high-capacitance case sizes ranging from 0402 to 1210, with capacitance values from 68 pF to 47,000 pF and voltage ratings spanning 4 to 100 V. These improvements significantly reduce component size, weight, and quantity, enabling engineers to design more efficient printed circuit boards (PCBs). Additionally, the capacitors incorporate KYOCERA AVX’s patented FLEXITERM termination technology, which enhances resistance to thermomechanical stresses during both assembly and operation.

As a result, MIL-PRF-32535 BME NP0 MLCCs are ideal for various high-reliability applications across aerospace and defense. Their applications include filtering, tuning, decoupling, timing, and blocking circuits in military equipment, satellite launchers, and communications systems, as well as Earth observation and science exploration satellites.

Michael Conway, Senior Product and Marketing Manager for High-Reliability Components at KYOCERA AVX, emphasized the company’s commitment to delivering high-quality solutions tailored to meet stringent demands in aerospace and defense applications. The introduction of new higher-capacitance options, specifically the 1206 and 1210 MLCCs, responds to the growing need for smaller and more durable military-qualified capacitors without compromising performance.

The MIL-PRF-32535 BME NP0 MLCCs are packaged in standard waffle configurations or offered on tape and reel. Current lead times for M-level reliability components are estimated at 18 weeks in the U.S. and Asia, while in Europe, they stand at 16 weeks. For T-level reliability components, lead times extend to 25 weeks in the U.S. and Asia, with 23 weeks in Europe.

For those looking to prototype and verify designs using MIL-PRF-32535 BME NP0 MLCCs for non-flight applications, the Engineering Module (EM) Range X7R BME MLCCs can be utilized. This range covers capacitors that adhere to ESCC 3009041, NASA S311-P838, and MIL-PRF-32535 specifications, using identical materials to qualified parts but without final DLA and European Space Components Coordination (ESCC) testing, thus accelerating lead times.
