Frequently Asked Questions
What automotive qualifications do specialty cores have?
Specialty automotive cores are AEC-Q200 qualified and manufactured under IATF 16949 standards. They meet ISO 26262 functional safety requirements and include PPAP documentation for automotive applications. All cores undergo rigorous testing including thermal cycling, vibration, shock, and salt spray testing.
What temperature range do automotive cores support?
Automotive cores operate reliably from -40°C to +155°C with excellent thermal stability. They withstand thermal cycling (1000 cycles), vibration (20G, 10-2000Hz), and shock (100G, 6ms) for 15+ year lifespan in harsh automotive environments.
Why use oval geometry for automotive cores?
Oval geometry optimizes magnetic performance in constrained automotive spaces, maximizing effective magnetic area while minimizing footprint. This design is particularly beneficial for EV powertrains and hybrid systems where space is at a premium.
