Slide 4: NASA EEE-INST-002: Overview
NASA EEE-INST-002: Overview “The purpose of this document is to establish baseline criteria for selection, screening, qualification, and derating of EEE parts for use on NASA GSFC space flight projects. This document shall provide a mechanism to assure that appropriate parts are used in the fabricat
Slide 5: NASA IEEE INST-002: Screening
NASA IEEE INST-002: Screening Screening is required for flight and qualification capacitors. Testing includes: • Visual and mechanical evaluation • Electrical Measurements • Thermal Shock • Voltage burn in • Surge current • High Impedance • Partial Discharge • Fine leak and gross leak Some tests onl
Slide 6: NASA IEEE INST-002: Qualification
NASA IEEE INST-002: Qualification Qualification testing is performed on capacitors from the same production lot as flight capacitors. The failure rate level helps determine Pass/Fail criteria. Quality tests derived from Mil standards. Company Confidential ©2022 Quantic Electronics. All rights reserv
Slide 7: NASA IEEE INST-002: Failure Rate Level (FRL)
NASA IEEE INST-002: Failure Rate Level (FRL) The FRL specifies how many parts must undergo a given test and the maximum number of failed capacitors allowed for the test to be considered passed. Voltage/Temperature Limit Test Example Level 1: 12 capacitors from the same production lot must be tested,
Slide 8: Mitigating Cost with Alternative Methods
Mitigating Cost with Alternative Methods “Commercial space” is adding costs pressure to space-based applications. AEC-Q200 is the automotive standard that has been used to establish reliability for space-based applications when the mission profile permits. Ask the capacitor manufacturer for parts wi
Slide 9: Design Criteria - Hermeticity
Design Criteria - Hermeticity For a capacitor to be considered “hermetic”, gasses and moisture cannot penetrate the capacitor, nor can they escape. Non-hermetic capacitors may be considered if used within a hermetic enclosure. Company Confidential ©2022 Quantic Electronics. All rights reserved. 9
Slide 10: Design Criteria - Radiation
Design Criteria - Radiation In space, electronics are fully exposed to radiation. Radiation Hardend, or “Rad-Hard” capacitors can still operate in the radioactive environments of space. Capacitors without a ”Rad-Hard” designation must implement a shielding solution. Company Confidential ©2022 Quanti
Slide 11: Design Criteria – Shock and Vibration
Design Criteria – Shock and Vibration During launch, the capacitor is exposed to high levels of vibration. Deployment events create a high shock condition which the capacitor must withstand. Capacitors must be able to withstand these shock and vibration levels and must be mounted in a secure way. Co
Slide 12: Design Criteria – Performance
Design Criteria – Performance Temperature will change the capacitor’s electrical characteristics. Quantic Evans P/N TDD3050333 Example ESR is higher at low temperatures. Capacitance is higher at high temperatures. Quantic Evans Temp vs ESR & Temp vs Capacitance curves Company Confidential ©2022 Quan
Slide 13: Design Criteria – Life & Derating
Design Criteria – Life & Derating Storage life is key for deep space missions or missions that may sit dormant for years before the capacitor is energized. Derating is used to increase the capacitor’s usable life as well as increase reliability. 50-60% voltage derate is typical. Company Confidential
Slide 14: Design Criteria – Understanding Failure Modes
Design Criteria – Understanding Failure Modes Consider the capacitor’s failure mode Solid tantalum capacitors may catch fire during some types of failure events. Additional design steps must be considered to account for this. There are some capacitor technologies that fail open or pose no fire risks
Slide 15: Design Criteria – Space, Weight and Power (Swap) Savings
Design Criteria – Space, Weight and Power (Swap) Savings There are cutting space grade capacitor solutions available today that reduce the number of capacitors needed, decreasing size and improving reliability. Company Confidential ©2022 Quantic Electronics. All rights reserved. 15
