Overview of UCY2H180MHD – Aluminum Electrolytic Capacitor, Radial Lead

The UCY2H180MHD is a radial-lead aluminum electrolytic capacitor rated at 500 V with a capacitance of 18 µF. It is designed for high-voltage power applications and offers a compact can-style package (φ12.5 × 30.5 mm) with 5 mm lead spacing for through-hole mounting.

With a rated temperature range of –40°C to 105°C, AEC-Q200 qualification, and a rated endurance of 10,000 hours at 105°C, this part targets demanding power-supply and automotive environments where high ripple current handling and long operational life are required.

Key Features

  • High Voltage Rating: 500 V rated voltage suitable for high-voltage DC-link and power-supply applications.
  • Capacitance & Tolerance: 18 µF with ±20% tolerance at 120 Hz, 20°C for predictable filtering performance.
  • Ripple Current Capability: Low-frequency ripple current 240 mA (120 Hz) and high-frequency ripple current 480 mA (100 kHz) to accommodate a range of switching and line-frequency conditions.
  • Electrical Loss: tanδ (DF) 0.24 measured at 20°C, 120 Hz, providing a defined dissipation characteristic for thermal and stability calculations.
  • Leakage Current: Specified leakage current of 460 µA for bias and insulation planning.
  • Reliability & Qualification: AEC-Q200 rated and long endurance—10,000 hours at 105°C—supporting sustained operation in harsh environments.
  • Package & Mounting: Radial lead can (φ12.5 mm diameter, 30.5 mm length) with 5.0 mm lead spacing and 0.5 mm spacing tolerance for through-hole assembly.
  • Operating Temperature: –40°C to 105°C to cover a broad range of ambient conditions.
  • Compliance: RoHS compliant and available in bulk (no terminal forming) or bag packing.

Typical Applications

  • Automotive power electronics: Suitable for high-voltage smoothing and filtering in automotive power-supply and control modules, supported by AEC-Q200 qualification.
  • Power supplies and DC-link circuits: Used for energy storage, filtering and ripple handling in high-voltage DC-link and converter applications.
  • Ballasts and lighting drivers: Recommended for ballast and lamp-driver circuits where high-voltage capacitance and reliable long-life operation are required.

Unique Advantages

  • High-voltage capability: 500 V rating enables use in elevated-voltage designs without stacking smaller capacitors.
  • Robust ripple handling: Specified ripple currents at both low and high frequencies reduce thermal stress and extend service life in switching applications.
  • Long endurance at elevated temperature: 10,000 hours at 105°C supports extended maintenance intervals and predictable lifespan planning.
  • Automotive-grade qualification: AEC-Q200 rating provides traceable qualification for automotive and similarly demanding applications.
  • Compact radial package: φ12.5 × 30.5 mm can with standard 5 mm lead spacing simplifies through-hole placement while keeping a small board footprint.
  • Regulatory compliance: RoHS compliance facilitates use in regulated production environments.
