The new DSCC 25007 Mini BME Stacks from KYOCERA AVX are miniature, high-CV stacked X7R capacitors that have been 100% Group A tested and include base metal electrodes (BME).
Based on its proven MIL-PRF-32535 X7R capacitors , the new fully-tested and traceable DSCC 25007 Mini BME Stacks are entirely unique to the market and are designed to meet the increasing demand for small and light high-CV SMT capacitors in high-reliability military, aerospace, and space applications subjected to harsh environments and extreme operating conditions.
Two horizontally stacked X7R multilayer ceramic chip capacitors (MLCCs) in an EIA 2220 package are currently available in the novel series. This packaging saves board space, has high-CV performance, and enables design engineers to downsize from components that are currently on the market.
Comparing it to larger, heavier stacked capacitors, it also shows low ESR, low impedance, good current handling capabilities, and superior shock and vibration resistance.
Additional characteristics include a range of lead frame alternatives, all with tin/lead plating, including regular two-foot J and L styles and paddle, or single bar foot J and L forms intended for better vibration resistance.
With three voltage ratings (25, 50, and 100V) and nine capacitance values ranging from 8.2 to 47µF ±20% tolerance, the first version of the DSCC 25007 Mini BME Stacks is qualified for operating temperatures between -55°C and +125°C.
The DLA-approved, MIL-PRF-32535 qualified facility that manufactures the new DSCC 25007 Mini BME Stacks is fully traceable and has undergone extensive testing to guarantee high reliability and performance in harsh environments and extreme conditions.
For particularly demanding designs with T-level requirements, 100% Group A testing or 100% Group A and Group B testing is required. Parts are shipped in two-chip package, tape and reel, or waffle pack.
A three-chip horizontal stack is anticipated to debut by Q1 2026 as part of the series’ future expansions, which will also comprise components with three to ten vertically stacked chips.
Applications
Ideal applications for the series extend throughout the military, aerospace, and space industries and include satellites and satellite launchers, military missiles and aircraft, and input/output filtering circuits in power supplies.
Leadership Comments
“We’re very excited to release the new DSCC Mini BME Stacks, as they’re engineered to solve design challenges that a growing number of our aerospace and defense industry customers have been wrestling with for the past few years, so they’re currently unique to market — the one component capable of delivering what they need,” said Michael Conway, Senior Product Marketing Manager – High Reliability Products at KYOCERA AVX. “Thanks to their compact and lightweight stacked form factor equipped with BME technology, these Mini Stacks deliver an unparalleled combination of high-reliability, high-capacitance, and high-voltage performance and substantial space and weight savings.
“In fact, when compared to an equivalent 100V, 10µF part with precious metal electrodes (PME), they’re approximately 1/9th the weight and 1/6th the volume. And component weight directly impacts things like aircraft operating costs, satellite launch costs, and missile performance and operating costs. So, this is huge!
“The new DSCC Mini BME stacks also come standard with 100% Group A testing and — since they utilize the inserts from our proven M32535 line — are fully traceable as well, which satisfies another common request for our aerospace and defense industry customers.”
