The UCY2V470MHD is a polarized radial-lead aluminum electrolytic capacitor offering 47 µF capacitance at a 350 V rating. It is a compact, high-ripple-current, long-life component intended for power filtering and smoothing in demanding electronic systems.

Engineered for reliability, the part combines a wide operating temperature range and extended endurance with packaging options suitable for through-hole assembly and bulk handling, making it well suited to industrial and automotive-grade power applications.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 350 V rated voltage and a capacitance tolerance of -20% to +20%.
• High ripple-current capability — Rated low-frequency ripple current of 510 mA at 120 Hz and high-frequency ripple current of 1.02 A at 100 kHz, enabling effective smoothing under AC and switching load conditions.
• Long endurance — Life rating of 12,000 hours at +105°C under rated voltage and ripple conditions for sustained performance in high-temperature environments.
• Temperature performance — Specified operating range from -40°C to +105°C for deployment across a broad thermal envelope.
• Loss and leakage characteristics — Tangent of loss angle (tan δ) of 0.24 measured at 20°C, 120 Hz, and a measured leakage current of 758 µA.
• Radial lead package — φ12.5 × 25 mm can with 5 mm lead spacing (±0.5 mm), polarized, supplied in Bulk (no terminal forming) or Bag packing.
• Quality and compliance — AEC-Q200 qualification and RoHS compliance.
• Frequency scaling — Ripple current frequency coefficient increases with frequency (e.g., 1.00 at 120 Hz, up to 2.00 at 100 kHz or more), enabling predictable behavior across switching frequencies.

Typical Applications

• Power supply filtering — Smoothing and bulk energy storage in AC–DC power supplies and DC link circuits to manage ripple and transient loads.
• Ballast and lamp drivers — Designed for ballast-style applications where sustained ripple handling and temperature endurance are required.
• Automotive electronics — Suitable for automotive systems that require components meeting AEC-Q200 qualification for robustness in vehicle environments.

Unique Advantages

• High ripple handling: Provides substantial low- and high-frequency ripple current ratings (510 mA at 120 Hz, 1.02 A at 100 kHz) to support switching supplies and associated filtering.
• Extended life at elevated temperature: Rated for 12,000 hours at +105°C, delivering predictable long-term capacitance stability and leakage performance under continuous load.
• Compact radial form factor: φ12.5 × 25 mm can with 5 mm lead spacing offers a small through-hole footprint for tight board layouts while retaining robust capacitance and voltage capability.
• Automotive-grade qualification: AEC-Q200 qualification indicates the part meets expanded reliability requirements for demanding applications.
• Predictable frequency response: Documented frequency coefficients for ripple current let designers scale ripple performance from 50 Hz through 100 kHz with confidence.
• Regulatory compliance: RoHS compliant for use in regulated supply chains.
