UCY2E470MPD

The UCY2E470MPD is a radial-lead aluminum electrolytic capacitor designed for high ripple current and long-life applications. It delivers 47 µF nominal capacitance at a 250 V rating in a compact φ10 × 30.5 mm can, optimized for power-supply and ballast circuits used in demanding environments.

Engineered for reliability, this part is AEC-Q200 qualified, RoHS compliant and specified for operation from −40 °C to +105 °C with a rated endurance of 12,000 hours at 105 °C.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a rated voltage of 250 V and tolerance of −20% to +20%.
• High Ripple Capability — Low-frequency ripple current of 405 mA at 120 Hz and high-frequency ripple current of 810 mA at 100 kHz, suitable for power supply filtering and decoupling under varying ripple spectra.
• Long Life Endurance — Rated for 12,000 hours at 105 °C under D.C. bias plus rated ripple current, with post-test limits of ±20% capacitance change, tan δ ≤ 200% of initial spec, and leakage current not exceeding initial specified value.
• Low Dissipation Factor — tan δ (loss tangent) maximum 0.20 measured at 20 °C, 120 Hz for the 250 V rating, supporting efficient energy handling.
• Leakage Current — Specified leakage current of 570 µA after one minute at rated voltage and 20 °C.
• Compact Radial Package — φ10 mm diameter × 30.5 mm length aluminum can with 5.0 mm lead spacing (±0.5 mm), radial lead mounting for through-hole assemblies; available in bulk or bag packing (no terminal forming).
• Environment & Compliance — RoHS compliant and AEC-Q200 qualified for demanding reliability applications.

Typical Applications

• Automotive Power Electronics — Bulk and smoothing capacitor for vehicle power supplies and auxiliary electronics where AEC-Q200 qualification and high temperature endurance are required.
• Power Supplies — Input/output filtering and ripple suppression in switching and linear power supplies thanks to high ripple current ratings at low and high frequencies.
• Ballast and Lighting Circuits — Energy storage and ripple handling in ballast applications as indicated by the product series guidance.

Unique Advantages

• High ripple tolerance across frequencies — Specified ripple currents at 120 Hz and 100 kHz provide clear performance expectations for both low- and high-frequency filtering needs.
• Proven long-term reliability — 12,000-hour endurance at 105 °C supports designs requiring extended life under elevated temperature and bias conditions.
• Automotive-capable qualification — AEC-Q200 qualification signals suitability for reliability-conscious automotive and transport electronics designs.
• Compact through-hole form factor — Small φ10 × 30.5 mm can and radial leads simplify layout for space-constrained through-hole assemblies while retaining substantial capacitance and voltage rating.
• Measured electrical characteristics — Explicit tan δ and leakage current specifications measured at standard conditions (20 °C, 120 Hz) make performance predictable during design and verification.
• RoHS compliant — Meets RoHS directive requirements for restricted substances.
