Frequently Asked Questions
What makes the AH series suitable for extreme temperatures?
The AH series uses advanced electrolyte formulations and construction techniques that enable operation up to 150°C. This includes high-temperature electrolyte, improved sealing, and enhanced electrode materials. These enhancements allow reliable operation in the most demanding automotive environments.
For extreme temperature applications, the AH series provides the highest reliability.
What is the expected lifetime at 150°C?
The rated lifetime is 2,000 hours at 150°C. While this may seem short compared to lower temperature ratings, it is excellent performance for such extreme conditions. In actual automotive use, operating temperatures are typically much lower, resulting in significantly extended field life.
The 150°C rating provides safety margin for extreme conditions while actual life is much longer at typical operating temperatures.
What applications require 150°C rated capacitors?
150°C rated capacitors are needed for extreme under-hood applications, EV charging systems, engine control units, transmission control modules, and other locations where temperatures can reach very high levels. Standard 125°C capacitors may not survive in these extreme environments.
Use 150°C capacitors for extreme temperature locations where 125°C ratings are insufficient.
What is the ripple current capability at high temperatures?
The rated ripple current is 1.2A at 150°C and 100kHz. This is impressive considering the extreme temperature. The ripple current capability increases at lower temperatures - approximately 1.7A at 125°C and 2.4A at 105°C.
For high ripple current at extreme temperatures, ensure adequate thermal management.
What voltage derating is recommended for 150°C operation?
For 150°C operation, conservative voltage derating is essential. Recommend 50% derating for this 63V capacitor - limit operating voltage to 32V. This provides margin for voltage transients and ensures reliable operation at extreme temperatures.
Use 50% voltage derating for 150°C operation to ensure maximum reliability.
Is PPAP documentation available for the AH series?
Yes, complete PPAP Level 3 documentation is available for AH series automotive capacitors. This includes all required documentation for automotive supplier qualification: design records, material certifications, AEC-Q200 test reports, process documentation, and ongoing reliability data.
