High Reliability Capacitor Solutions

Our High Rel products are designed for optimum reliability and are burned in at elevated voltage and temperature levels. They are 100% electrically inspected to ascertain conformance to a strict performance criteria. 

Applications for High Reliability products include medical implanted devices, aerospace, airborne, various military applications, and consumer uses requiring safety margins not attainable with conventional product qualifications.

Our testing expertise covers the major standards encountered in Automotive (through AEC-Q200), Military and Aerospace (through IECQ-CECC and MIL standard testing), Medical (for example with the application of MIL-PRF-55681 and MIL-PRF-123 to medical implantable applications and Space (Space grade tested in accordance with ESCC3009 (refer to Knowles Spec S02A 0100) or MIL Grade (in accordance with MIL-PRF-123, MIL- PRF-55681))

High Reliability For Automotive

Knowles Capacitors is a manufacturer of high quality automotive grade components. With the broadest range of AEC-Q200 approved MLC capacitors, Tandem and Open Mode MLC capacitors, X8R High temperature MLC capacitors and EMI filters up to a voltage rating of 4kV we provide for the requirements of modern automotive applications including EV and HEV systems. For more information on Electric Vehicle drivetrains and the role our Capacitors play please also visit our Electric Vehicle Solutions Page and AEC-Q200 Product Page.

High Reliability For Military and Aerospace

For applications such as Mil / Aerospace where reliability is paramount, Knowles Precision Devices holds the IECQ-CECC internationally recognized qualification for surface mount ceramic capacitors tested in accordance with the requirements of IECQ-CECC QC32100. To learn more you can download our IECQ-CECC application note

We also conduct a range of MIL standard testing covering MIL-PRF-55681, MIL-PRF-123, MIL-PRF-39014, MIL-PRF-49467, MIL-PRF-49470 (DSCC 87106) and MIL-PRF-38534.

High Reliability For Medical

The two main SCD specifications for medical components are MIL-PRF-55681 and MIL-PRF-123
