Automotive Electronics Capacitor Solutions

HJC maintains comprehensive automotive certifications: 1) IATF 16949 - Automotive Quality Management System covering design, development, production, and service, 2) AEC-Q200 Qualification - For passive components including temperature cycling, mechanical shock, vibration, and humidity testing, 3) ISO 9001 - General quality management, 4) ISO 14001 - Environmental management. HJC's automotive capacitors undergo 100% screening including electrical testing, visual inspection, and dimensional verification. Full PPAP documentation (Level 3) is available including control plans, FMEA, and MSA studies.

Request PPAP documentation and qualification reports for automotive projects; all HJC automotive products are fully certified.

HJC offers several capacitor types for EV applications: 1) X8R MLCCs - For battery management systems, motor controllers, and onboard chargers operating up to 150°C, 2) High-Temperature Electrolytics - For powertrain applications requiring long life at high temperatures, 3) Film Capacitors - For DC-link filtering in inverters and onboard chargers, 4) Supercapacitors - For regenerative braking energy storage and 12V backup systems. Key specifications for EV: Voltage ratings up to 1000V for high-voltage systems, Temperature ratings to 150°C for power electronics, AEC-Q200 qualification for all safety-critical applications, High ripple current capability for inverter output filtering.

Contact our automotive FAE for EV-specific capacitor recommendations based on your voltage and temperature requirements.

X7R and X8R are both Class II ceramic dielectrics with different temperature ranges: 1) X7R - Temperature range -55°C to +125°C, capacitance change ±15% over range, suitable for most automotive interior applications, 2) X8R - Temperature range -55°C to +150°C, capacitance change ±15% over range, required for under-hood and powertrain applications. Selection guide: Use X7R for infotainment, body electronics, and cabin applications

use X8R for engine compartment, motor drives, battery systems, and LED headlamps. X8R capacitors have slightly higher cost but are essential for high-temperature automotive applications. Both dielectrics are available with AEC-Q200 qualification and flexible terminations.

Use X8R for temperatures above 125°C; X7R is sufficient for interior applications up to 125°C.

Yes, HJC provides full PPAP (Production Part Approval Process) documentation for automotive customers: 1) Level 3 PPAP - Includes all customer requirements including submission of actual measurement data, 2) Documentation Package - Design records, engineering change documents, customer engineering approval, design FMEA, process flow diagram, process FMEA, control plan, measurement system analysis, dimensional results, material/performance test records, initial process studies, qualified laboratory documentation, appearance approval report, sample production parts, master sample, checking aids, and customer-specific requirements. Lead time for PPAP is typically 4-6 weeks after sample approval. Contact our automotive sales team to initiate PPAP for your project.

Request PPAP Level 3 for all automotive production parts; allow 4-6 weeks for completion.

Flexible termination (soft termination) is a technology that reduces stress on ceramic capacitors from board flexure: 1) Construction - A compliant polymer layer between the ceramic body and metal termination absorbs mechanical stress, 2) Benefits - Prevents cracking from PCB bending, thermal cycling, and vibration, 3) Applications - Required for high-stress locations: large case sizes (1210 and above), under-hood applications, high-vibration areas, large temperature cycling ranges. HJC offers flexible termination options on most automotive MLCCs. Identification: Part number suffix or specific series designation. Testing: Flexible termination capacitors pass additional board flex testing per AEC-Q200. Cost: Approximately 10-15% premium over standard termination.

Use flexible termination for case sizes ≥1210, under-hood applications, and high-vibration environments.

HJC maintains complete lot traceability for all automotive capacitors: 1) Lot Number System - Each production lot has unique identifier traceable to raw materials, production date, equipment, and operators, 2) COFC Documentation - Certificate of Fitness for Conformance provides lot-specific test data, 3) Material Traceability - Ceramic powders, electrodes, and terminations are traced to suppliers and incoming inspection, 4) Production Records - Complete manufacturing data including process parameters and inspection results, 5) Test Data - Electrical test results for each lot including capacitance, dissipation factor, insulation resistance, and dielectric withstanding voltage. Retention period: 15+ years for automotive parts. Customers can request lot-specific data and certificates for quality management and failure analysis.

Request COFC and lot traceability data with each shipment for automotive production.
