Frequently Asked Questions

What AEC-Q100 grade is available?

3peak automotive components are qualified to AEC-Q100 Grade 1 (-40°C to +125°C), which is the highest temperature grade. This covers all automotive under-hood and passenger compartment applications. Grade 0 (-40°C to +150°C) may be available for specific products - contact FAE for details.

Grade 1 standard. Grade 0 available for some products on request.

Is PPAP documentation available?

Yes, 3peak provides PPAP (Production Part Approval Process) documentation for automotive customers. Available levels: PPAP Level 3 (full documentation including PSW, dimensional results, material certifications, performance test results, process flow, FMEA, control plan). Contact BeiLuo to request PPAP documentation for your specific project.

PPAP Level 3 available. Contact FAE to request documentation package.

What EMC requirements does this solution meet?

The automotive solution meets stringent EMC requirements: CISPR 25 Class 5 for conducted and radiated emissions, ISO 11452 for immunity to radiated disturbances, ISO 7637 for transient immunity, ISO 10605 for ESD protection. Components feature enhanced EMC robustness including integrated filtering and protection. Contact FAE for specific EMC test reports.

Meets CISPR 25 Class 5 and ISO automotive EMC standards. Contact FAE for test reports.

How does automotive grade differ from industrial grade?

Automotive grade (-Q1) differs from industrial grade in several ways: Extended temperature range (-40°C to +125°C vs -40°C to +85°C), Additional qualification testing per AEC-Q100, Enhanced EMC performance, PPAP documentation support, Traceability and change control, Higher reliability requirements. Always use automotive grade for automotive applications to ensure reliability and qualification.

Always use -Q1 automotive grade for automotive applications. Do not substitute with industrial grade.

What is the typical qualification timeline?

Automotive qualification timeline: Component qualification (AEC-Q100): 3-6 months, System design and testing: 2-3 months, PPAP documentation: 1-2 months, OEM approval: 1-3 months. Total timeline from design start to production: 6-12 months depending on complexity. BeiLuo provides support throughout the qualification process including PPAP documentation assistance.

Plan 6-12 months for complete automotive qualification. Engage FAE early in process.
