X8R and X8L dielectric components are added to the high-reliability APS Series multilayer ceramic capacitors (MLCCs) for commercial off-the-shelf (COTS) applications. Extensively tested using many of the MIL-STD test methods as used in MIL-PRF-55681, which negates the need for customer-specific drawings, APS Series MLCCs exhibit a field failure rate of <1ppb. Now available in NP0, X7R, X8R, and X8L dielectrics, in addition to a wider capacitance range than MIL spec parts, these surface mount MLCCs satisfy COTS requirements for higher CV demands and PCB space-saving requirements and provide high-reliability.
APS Series MLCCs are available in six case sizes spanning 0603 to 2220, six voltages spanning 16V to 500V, and capacitance values spanning 10 pF to 22 µF. They are also available in four dielectrics (NP0, X7R, X8R, and X8L), three capacitance tolerances (±5%, ±10%, and ±20%), and four terminations: plated NiSn, 5% minimum lead, and, for X7R MLCCs, Flexiterm, which delivers improved thermo-mechanical stress resistance, and Flexiterm with 5% minimum lead.
In addition to the various MIL-STD test methods used to ensure the series’ high-reliability of under 1ppb failure rate, APS Series capacitors are also subjected to AVX’s in-house Maverick lot review system, which eliminates infant mortality failures, as well as to thermal shock testing, 85/85 testing, life testing at 125°C and two times the rated voltage, and 100% visual inspection.
