HJC (Huarong) Products

HJC manufactures four main categories of capacitors: 1) MLCC (Multilayer Ceramic Capacitors) - available in C0G, X7R, X5R, and Y5V dielectrics for general purpose and high-frequency applications, 2) Aluminum Electrolytic Capacitors - including radial, SMD, and snap-in types for power supply filtering and energy storage, 3) Film Capacitors - metallized polyester (PET) and polypropylene (PP) film capacitors for industrial and automotive applications, 4) Supercapacitors (EDLC) - electric double-layer capacitors ranging from 0.1F to 3000F for backup power and energy harvesting. All products are available in standard and automotive-grade (AEC-Q200) versions.

Browse our product categories below to find the specific HJC capacitor type suitable for your application requirements.

Selecting the right HJC capacitor involves several key steps: 1) Determine Capacitor Type - MLCC for high-frequency/decoupling, electrolytic for bulk capacitance, film for AC/DC filtering, supercapacitor for energy storage, 2) Define Electrical Requirements - capacitance value, voltage rating, tolerance, ESR requirements, 3) Consider Environmental Conditions - operating temperature range, humidity, vibration, 4) Evaluate Application Requirements - automotive (AEC-Q200), industrial, or consumer grade, 5) Check Physical Constraints - package size, mounting type (SMD/through-hole), 6) Review Lifetime Requirements - operating hours, ripple current capability. HJC provides detailed datasheets and application notes for each product family. Our FAE team can assist with selection based on your specific requirements.

HJC automotive-grade capacitors are qualified to AEC-Q200 standards with key differences from standard products: 1) Temperature Range - Automotive: -55°C to +150°C (X8R) or +125°C (X7R); Standard: -55°C to +85°C or +105°C, 2) Reliability - Automotive: Higher qualification requirements including thermal cycling, mechanical shock, and humidity testing, 3) Traceability - Automotive: Full lot traceability and PPAP documentation, 4) Quality Control - Automotive: Stricter process controls and inspection criteria, 5) Price - Automotive: Typically 20-30% premium over standard grade, 6) Applications - Automotive: EVs, ADAS, powertrain; Standard: Consumer electronics, general industrial. Both grades maintain HJC's quality standards, but automotive-grade products undergo additional testing and certification.

Choose automotive-grade (AEC-Q200) for automotive applications; standard grade is sufficient for industrial and consumer applications.

Yes, HJC offers custom capacitor solutions for high-volume applications. Customization options include: 1) Electrical Parameters - special capacitance values, voltage ratings, or tolerance requirements, 2) Physical Dimensions - modified case sizes or lead configurations, 3) Terminations - custom plating or termination materials, 4) Packaging - tape and reel specifications, special packaging, 5) Marking - custom part marking or date coding, 6) Performance Characteristics - enhanced temperature performance, reduced ESR, or extended life. Custom development requires minimum order quantities (typically 100K+ units for MLCC, 10K+ for electrolytics) and engineering development time (8-16 weeks). HJC's application engineering team works closely with customers to develop custom solutions that meet specific application requirements while maintaining cost competitiveness.
