MLCCs for Aerospace & Defense

MLCC Technology from High-Q to Pulse Energy

From military aircraft to electronic warfare defense systems, aerospace and defense applications are placing new demands on power electronics. Defense electronics systems must function reliably for their lifetime while operating at higher voltages and wider temperature ranges, and all while becoming smaller, lighter, and consuming less power.

Our expertise in ceramic material science and advanced manufacturing techniques enables us to design and produce high-quality components optmized for SWAP-C.

With over 40 years of experience developing high-performance components for mission-critical aerospace and defense applications, we can supply, test and screen the exact high reliability components you need. 

High Reliability is a Must

Since the consequences of failure of even the smallest component in an aerospace and defense application can be dire, and many of these applications have long lifespans, all the jobs we just discussed must be performed by high-reliability components. High-reliability components are made from the same high-quality materials as standard components, but high-reliability components are subjected to additional screening and testing to ensure long-term reliability.

The most common methods used for screening components for reliability are based on established military specifications (MIL-SPECS). The following are three of the most frequently used MIL-SPECS for screening today:

  • MIL-PRF-55681 – A general purpose military high-reliability specification
  • MIL-PRF-49467 – Covers requirements for general purpose, ceramic multilayer high voltage capacitors
  • MIL-PRF-123 – Provides an increased level of reliability over MIL-PRF-55681 and is commonly used for space applications

When screening MLCCs using MIL-SPECS, components are powered up from 100 percent to 200 percent of the voltage rating while being brought up to an operating temperature of 125 degrees for 100 or more hours. All this stringent testing is applied to 100 percent of the MLCCs in the lot to ensure each component coming out of the factory is in pristine condition and is likely to sustain high performance over the application’s lifespan. 

Whether you need a specialty capacitor for a detonator application, an EMI filter for a sensitive military communication device, or MLCCs for a range of jobs in your aircraft’s power system, we thrive on working with companies that have technically challenging requirements and applying our expertise to deliver right solution.
