Presidio Components High Reliability "HR" Ceramic 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.

Quality Assurance Provisions
Every lot undergoes the following inspection and tests:

• Voltage Conditioning Tests: All parts receive a voltage conditioning at 2X rated voltage and 125°C for a minimum of 8 hours. An accelerated voltage conditioning, following MIL-PRF-55681 guidelines, may be used at Presidio's discretion.
  
  
• Capacitance Tests: All parts are tested at 25°C and 1VACRMS in accordance with Method 305 of MIL-STD-202.
