Overview of UCYW6270MHD – 420 V, 27 µF Radial Aluminum Electrolytic Capacitor

The UCYW6270MHD is a polarized, radial-lead aluminum electrolytic capacitor from Nichicon's UCY series, designed for compact high-voltage DC applications. It combines a 27 µF capacitance with a 420 V rated voltage in a miniature φ12.5 × 25 mm can for through-hole assemblies.

Engineered for long endurance and elevated ripple performance, this part addresses demanding power-supply and ballast applications and is qualified to AEC-Q200 for automotive use. Key value propositions include high ripple-current capability, extended 105°C life, and industry-standard radial packaging options.

Key Features

  • Electrical Performance — 27 µF capacitance with a 420 V rated voltage, polarization suited for high-voltage DC circuits.
  • High Ripple Current — Low-frequency ripple current of 340 mA at 120 Hz and high-frequency ripple current of 680 mA at 100 kHz, enabling robust handling of AC components on DC rails.
  • Long Endurance — Rated for 12,000 hours at 105°C under rated voltage and ripple conditions for extended field life in thermally stressed environments.
  • Thermal & Frequency Characteristics — Operating temperature range from −40°C to 105°C; tan δ (loss factor) of 0.24 measured at 20°C, 120 Hz for predictable AC loss behavior.
  • Compact Radial Package — φ12.5 mm diameter × 25 mm length can with 5.0 mm lead spacing (±0.5 mm) for straightforward through-hole mounting and mechanical stability.
  • Leakage Current — Specified leakage current of 553.6 µA, defined per rated capacitance and voltage conditions.
  • Compliance & Qualification — RoHS-compliant and AEC-Q200 qualified for automotive applications.
  • Packaging Options — Available bulk (no terminal forming) and bag packing to support prototyping and production workflows.

Typical Applications

  • Automotive electronic systems — AEC-Q200 qualification and 105°C endurance make this capacitor suitable for automotive modules requiring high-voltage filtering and energy buffering.
  • Power supplies and ballasts — Designed for power-supply and ballast applications where high ripple current capability and long life at elevated temperature are required.
  • Compact high-voltage DC circuits — The 420 V rating and miniature radial package suit space-constrained designs needing through-hole, high-voltage capacitors.

Unique Advantages

  • High ripple tolerance: Specifies 340 mA at 120 Hz and 680 mA at 100 kHz, reducing stress on upstream components in power conversion applications.
  • Extended operating life: 12,000-hour endurance at 105°C gives designers predictable long-term performance in hot operating environments.
  • Automotive-capable: AEC-Q200 qualification supports use in vehicle electronics where industry-level qualification is required.
  • Space-efficient through-hole format: φ12.5 × 25 mm can and 5 mm lead spacing deliver a compact footprint for legacy PCBs and robust mechanical mounting.
  • Production-friendly packaging: Available in bulk and bag packing to accommodate both small-batch development and larger assembly volumes.
  • Regulatory compliance: RoHS-compliant construction simplifies regulatory tracking and material compliance in finished products.
