Hi-Rel Components and Applications

Micross understand the Hi-Rel industry and their need for reliability. We are able to provide Palladium Silver terminations, a unique solution to hybrid manufacturers whose design requires a conductive epoxy attach. Tin plated nickel terminations are also available for those designs that require solder.

Product Available

Both are available with a Palladium-Silver termination for Hybrid applications or Nickel-Barrier for Soldering.

Micross can also offer High Value capacitors, up to 10KV in Class I and II dielectrics with low ESR. High Frequency (High-Q) capacitors are also available which provide excellent, low loss performance for applications under 3GHz. Please ask for more details.

For Commercial Applications we can provide:

EIA Class III General Purpose

Dielectric: Y5V/Z5U
Temp Coefficient Y5V: +22 –82%
Temp Coefficient Z5U: +22 –56%
Ageing Rate: 2% per decade
Design: Surface Mount

Typically used in applications where capacitance change over temperature is not a critical requirement, these components are available in Gold or Tin Plated Nickel.

Military-Grade Components

Micross Components can offer wide range of Military Grade components including:

MIL (BX/BP Grade) – Tested to MIL PRF 55681. BX has voltage temperature limits in addition to the standard temp limits of the X7R. The BX dielectric is limited to a +- 15% max capacitance change from -55°C to 125°C, and to a +15% -25% maximum change with a working voltage applied.

IECC-CECC – These are a range of Hi-Rel MLCC suitable in critical or high reliability applications. 100% fully tested, they are available with C0G and X7R dielectrics and are released to the following ranges:

• Released in Accordance to IECC-CECC QC32100
• Qualified to the requirements of AEC-Q200
• Qualified to the requirements of ESCC 3009 European Space Specification

EIA – Available as Class II Stable High-Temp, these have a temperature range of –55°C to 200°C with a 0% ageing rate. Popular EIA caps are also offered in Thin-Profile design, suitable for height-sensitive applications.

Hybrid & HDI Chip Capacitors

Micorss can support wire-bondable thin film Si Capacitor chips which are a desired choice for Hybrid and HDI assemblies.

• Small Size
• Excellent Performance
• High Capacitance Values from 1 – 1000pF
• Two different topologies are offered for single or parallel connections.

Testing and Qualification

Standard Components can be tested to:

MIL PRF 55681 - General purpose military high specification for SM components.

MIL PRF-123 – This level provides increased reliability above that of the MIL-PRF 55681. Recommended for Space, Medical implantable and life support applications.

MIL PRF 38534 – Two classification levels for reliability available with this specification. Class H is for standard Military quality level and Class K is the highest reliability intended for Space application.

Micross work with our suppliers to offer our customers the most suitable component for their application and can therefore test in accordance to a customers SCD specification.
