Overview of UCY2W180MPD – 18 µF, 450 V Radial Aluminum Electrolytic Capacitor

The UCY2W180MPD is a radial-lead aluminum electrolytic capacitor designed for high-voltage, high-reliability power applications. It provides 18 µF capacitance at a 450 V rating in a compact φ10 × 30.5 mm can with 5 mm lead spacing.

Engineered for long endurance and robust ripple handling, this part targets power supply and ballast applications and is specified for automotive use with AEC‑Q200 qualification. It is RoHS compliant and available in bulk or bag packaging for production-level sourcing.

Key Features

  • Capacitance & Tolerance — 18 µF with ±20% tolerance (‑20%~20%) at 120 Hz, 20°C for predictable energy storage and decoupling.
  • High Voltage Rating — Rated for 450 V DC to support high-voltage power rails and ballast circuits.
  • Low Loss (tan δ) — tanδ = 0.24 measured at 20°C, 120 Hz, suitable for designs that require controlled dissipation characteristics.
  • Ripple Current Capability — 215 mA at 120 Hz (low frequency) and 430 mA at 100 kHz (high frequency), enabling effective smoothing under ripple-loaded conditions.
  • Leakage Current — Specified leakage current of 424 µA, measured after voltage application conditions as defined in the product specification.
  • Long Endurance — Rated life of 12,000 hours at 105°C, supporting extended operation in elevated-temperature environments.
  • Temperature Range — Operational from ‑40°C to +105°C to cover wide environmental conditions.
  • Package & Mounting — Radial lead can (φ10 × 30.5 mm) with 5.0 mm lead spacing (±0.5 mm); available as bulk (no terminal forming) or bag packed for production handling.
  • Qualification & Compliance — AEC‑Q200 qualified and RoHS compliant, indicating suitability for regulated and automotive-focused designs.

Typical Applications

  • Power Supplies — Bulk filtering and smoothing on high-voltage DC rails where 450 V rating and 18 µF capacitance are required.
  • Ballasts and Lighting — AC/DC ballast circuits that need stable capacitance, controlled dissipation, and long operational life at elevated temperature.
  • Automotive Power Electronics — High-voltage sections within automotive power systems where AEC‑Q200 qualification and extended endurance are needed.

Unique Advantages

  • 450 V Rating for High-Voltage Designs: Enables use on higher-voltage DC rails without compromising capacitance or endurance.
  • High Ripple Current Handling: Defined ripple currents at both low (215 mA @120 Hz) and high (430 mA @100 kHz) frequencies provide flexibility across switching and line-frequency applications.
  • Extended Life at Elevated Temperature: 12,000-hour endurance at 105°C supports reliable long-term operation in thermally demanding environments.
  • Automotive-Grade Qualification: AEC‑Q200 rating supports use in regulated automotive and transportation applications requiring component-level qualification.
  • Compact Radial Form Factor: φ10 × 30.5 mm can with 5 mm lead spacing simplifies PCB layout for through-hole power assemblies.
  • Regulatory Compliance: RoHS compliant to meet environmental requirements for commercial and automotive programs.
