High Performance Capacitor Solutions (KEMET)

Product Characteristics:

● Full technology platform coverage: Provide MLCC (X7R/X8R/C0G), polymer aluminium electrolytic (KO-CAP™), tantalum capacitors (Tantalum), film capacitors (Film) four major technology routes, package sizes from 0603 (1.6mm x 0.8mm) to large cylindrical (Ø40mm x 50mm), capacity range 0.1pF to 100mF, voltage level2.5V to 10kV, to meet the needs of high-density SMT to high-power industrial systems in all scenarios;

● Extreme reliability in extreme environments: Automotive MLCCs (X8R series) support -55°C to +150°C operation with a capacitance drift rate of <±10% (C0G@-200°C~+175°C); polymer capacitors have passed 3,000 cycles of -55°C ↔ +125°C thermal shock and 2,000 hours of dual 85 tests, making them suitable for ultra-harsh environments such as geothermal drilling sensors and spacecraft power buses;

● High Frequency Low ESR with High Ripple Capability:

  • MLCC: ESR as low as 2mΩ (@100kHz), SRF over 10GHz, ripple current up to 3A @100kHz (1210 package)
  • Polymer capacitors: ESR <5mΩ (@100kHz), can carry 20A RMS ripple current (Ø10mm series)
    Suitable for energy-efficient systems such as AI server GPU power supply and magnetic resonance imaging (MRI) gradient amplifiers;

● Military-grade vibration-resistant and long-life design:

  • MLCC: 50G shock/25G vibration with FlexiCap™ crack-resistant construction (MIL-STD-202)
  • Tantalum Capacitors: F-Tech™ Reinforced Technology, Failure Rate <0.01 FIT (MIL-PRF-55365)
  • Film capacitors: Self-healing characteristics ensure >1,000,000 hours of life (70°C full load)
    Meet strong vibration scenarios such as armoured vehicle fire control systems and ship propulsion inverters;

● High Voltage and Safety Certification Series:

  • 10kV ceramic/film capacitors UL/ENEC approved, dV/dt >50kV/μs (C4AK series)
  • A758 Series Polymer Capacitors Conform to AEC-Q200 Grade 0 (-50°C~+150°C)
  • Safety certified capacitors (Class X2/Y1) meet IEC 60384-14 reinforced insulation requirements;

● Smart Technology and Global Compliance:

  • SmartCap™ Series with Integrated Voltage/Temperature Sensing Supports Digital Monitoring
  • RoHS 2.0/REACH compliant, MLCCs certified by Automotive Electronics Council AQG-324
  • Provide localised replacement solutions (e.g. KO-CAP™ to replace electrolytic capacitors), covering emerging areas such as new energy vehicle triboelectric systems and renewable energy storage.

Typical Applications:

  • Electric Vehicle 800V Platform OBC Resonant Circuit (Film Capacitor)
  • Industrial Inverter IGBT Buffer Protection (MLCC + Polymer Capacitor Hybrid Solution)
  • 5G millimetre wave phased array radar power supply network (low ESL tantalum capacitors)
  • Space Station Life Support System Power Filtering (Aerospace Grade MLCC)
