Capacitor Finder
Micross Components are able to support both Active and Passive components for a wide range of applications, in particular, Military, Space and Automotive markets. We offer an extensive array of capacitors with a variety of dielectrics that are tailored for both Hi-Rel and commercial applications.
We understand the Hi-Rel industry and their need for reliability. We are able to provide Palladium Silver terminations, a unique solution to a hybrid manufacturer whose design requires a conductive epoxy attach. Tin plated nickel terminations are also available for those designs that require solder.
Kitting Solutions
By sourcing both semiconductors and capacitors from Micross Components, our customers are able to complete their full kits from one supplier. As a result, customers are able to reduce their supplier lines whilst receiving full technical and customer support. If you are unable to find the capacitor you require using our tool above, our dedicated sales team will find you a suitable alternative.
Hi-Rel
NPO/COG dielectrics are ultra stable Class I devices with an operating temp of -55°C to 125°C and 0% aging rate. In addition to this, their linear temp coefficient, low loss and stable electrical properties with time, frequency and voltage make them a perfect candidate for circuitry requiring a very stable current.
For Military and Space applications that require higher reliability, COG, BX, and X7R chips can be tested in accordance to MIL PRF 55681, MIL PRF-123, MIL PRF-49467 or SCD to enable optimum reliability.
X7R Dielectric is a stable EIA Class II dielectric with +/-15% temp coefficient and predictable variation of electrical properties with time, temperature and voltage. These chips can also be tested in accordance to MIL PRF 55681, MIL PRF-123, MIL PRF-49467 or SCD to enable optimum reliability.
Hi-Temp
For extreme heat applications, such as Oil Exploration and Automotive/Aeronautical engine circuitry, a range of surface mount devices in sizes 0805 to 7565 are available in NP0/COG that can meet -55°C to 200°C. Please ask for our Leaded encapsulated devices in sizes 1515 to 7565 for additional high temperature capacitors.
Hi-Rel Applications
The Military specification for ceramic chip capacitors MIL PRF 55681 also defines the Mid-K stable and is designated with the 'BX' characteristic. This 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.
Y5V/Z5U dielectric is a general-purpose EIA Class III device, which can be used where capacitance change over operating temperature is not critical. These capacitors have a very high capacitance density with +22% to -56% (Z5U) and +22% -82% (Y5V) temp coefficient. As a result, these components are available in Gold, or Tin Plated Nickel, not Palladium Silver.
