UCY2W470MHD

The UCY2W470MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UCY series. It is a radial-lead, polarized can designed for high-voltage applications requiring elevated ripple handling and extended operational life.

Typical use cases include power supplies and ballast circuitry, and the device is specified for automotive applications where AEC-Q200 qualification, long life, and broad temperature tolerance are required.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance at a rated voltage of 450 V, with a capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• High ripple current capability — Specified low-frequency ripple current of 525 mA at 120 Hz and high-frequency ripple current of 1.05 A at 100 kHz, with frequency coefficients available to scale ripple current at other frequencies.
• Long operational life — Rated for 12,000 hours at +105°C under DC bias plus rated ripple current; after life test, capacitance remains within ±20% and leakage does not exceed initial specified values.
• Loss characteristics — Tangent of loss angle (tan δ) specified at a maximum of 0.24 (measured at 20°C, 120 Hz for 450 V units), supporting stable AC behavior for power applications.
• Temperature range — Qualified for operation from −40°C to +105°C.
• Mechanical package — Radial can with dimensions φ12.5 × 40 mm (diameter × length) and 5.0 mm lead spacing (lead spacing tolerance ±0.5 mm); available in bulk or bag packing (no terminal forming).
• Leakage current — Specified leakage current 946 µA for this part number (measured per product data conditions).
• Standards & compliance — RoHS compliant and AEC‑Q200 qualified.

Typical Applications

• Power supplies — Bulk and smoothing capacitor for high-voltage power supply rails where high ripple current and long life are required.
• Ballast circuits — Suited for ballast applications called out in the UCY series specification, providing stable capacitance under sustained stress.
• Automotive power electronics — AEC‑Q200 qualification and wide temperature range make this capacitor appropriate for automotive power subsystems that require extended endurance at elevated temperature.

Unique Advantages

• Proven long life at elevated temperature — 12,000 hours endurance at +105°C ensures predictable drift and retention of electrical characteristics for designs with long operational duty cycles.
• High-frequency and low-frequency ripple handling — Distinct ripple current ratings for 120 Hz and 100 kHz (with published frequency coefficients) let designers size capacitors accurately across switching and line-frequency use cases.
• Reliable electrical stability — Specified tan δ and leakage behavior under rated conditions translate to consistent performance in power conversion and filtering applications.
• Automotive-capable qualification — AEC‑Q200 qualification supports use in demanding automotive electronics environments requiring component-level reliability assurance.
• Compact radial can format — φ12.5 × 40 mm package with 5 mm lead spacing provides a small footprint for high-voltage capacitance in space-constrained assemblies.
• Regulatory compliance — RoHS compliance supports use in regulated production environments.
