High Reliability "CR" Capacitors (Tested similarly to MIL-PRF-55681)

For applications that require a high level of reliability, Presidio recommends its high reliability “CR” capacitors. Tested similarly to Mil-PRF-55681 Group A, Presidio manufactures these chips on the same manufacturing line as its military product line. They may be used in both military and space applications. Please note these capacitors are NOT Mil-qualified.

Standard Testing for "CR" capacitors

Example Part Number: CR0805BX103K2P3

The part number can be made by adding "CR" to the beginning of the standard Presidio part number. See guidelines in the Part Number Definitions portion of this website.

 

High Reliability "SR" Capacitors (Tested similarly to MIL-PRF-123 Group A)

For applications that require the highest level of reliability, Presidio recommends its high reliability “SR” capacitors. Tested similarly to Mil-PRF-123 Group A, Presidio manufacturers these chips on the same manufacturing line as its military product line. They may be used in both military and space applications. Please note these capacitors are NOT Mil-qualified.

Standard Testing for "SR" capacitors

Example Part Number: SR0805BX103K2P

The part number can be made by adding "SR" to the beginning of the standard Presidio part number. See guidelines in the Part Number Definitions portion of this website.

 

High Reliability "HR" Capacitors

For applications where reliability, but not full military screening is required, Presidio recommends its high reliability “HR” capacitors. The “HR” code signifies use of the test program below, or the use of a customer Source Control Document (SCD) that includes voltage conditioning.

Standard Testing for "HR" capacitors

Example Part Number: HR0805BX103K2P3

The part number can be made by adding "HR" to the beginning of the standard Presidio part number. See guidelines in the Part Number Definitions portion of this website.
