UCY2E470MPD9

The UCY2E470MPD9 is a miniature, high‑reliability aluminum electrolytic capacitor in a radial‑lead can designed for demanding power applications. It delivers 47 µF at a 250 V rating with a compact φ10 × 25 mm package and 5 mm lead spacing.

Engineered for long life and robust ripple handling, this AEC‑Q200 qualified, RoHS‑compliant unit is targeted at automotive electronics and industrial power supply and ballast applications that require sustained performance across –40°C to +105°C and up to 12,000 hours endurance at 105°C.

Key Features

• Capacitance & Voltage: 47 µF nominal capacitance with a 250 V rated voltage and tolerance of −20% to +20%.
• High ripple current capability: Low‑frequency ripple current 345 mA at 120 Hz and high‑frequency ripple current 690 mA at 100 kHz, enabling effective smoothing across a wide frequency range.
• Frequency ripple coefficients: Frequency coefficients from the UCY series apply (e.g., 1.00 at 120 Hz, 2.00 at 100 kHz) for calculating allowable ripple at different frequencies.
• Low loss and leakage: Tangent of loss angle (tan δ) 0.20 (measured at 20°C, 120 Hz) and specified leakage current of 570 µA.
• Long life & wide temperature range: Endurance 12,000 hours at 105°C with an operating temperature range of −40°C to +105°C.
• Automotive qualification & compliance: AEC‑Q200 qualified and RoHS compliant for applications requiring automotive‑grade reliability and environmental compliance.
• Radial lead, compact package: φ10 × 25 mm can with 5.0 mm lead spacing (±0.5 mm) and radial lead mounting for through‑hole assembly; available in bulk or bag packing.

Typical Applications

• Automotive electronics: Energy storage and smoothing in automotive power modules and control units where AEC‑Q200 qualification and high temperature endurance are required.
• Power supplies: Bulk smoothing and ripple suppression in industrial and vehicle power supplies, taking advantage of high ripple current capability and long life at 105°C.
• Ballasts and lighting power: DC link and filtering use in ballast circuits where compact size and sustained ripple handling improve system stability.

Unique Advantages

• Designed for sustained high‑temperature operation: 12,000 hours endurance at 105°C provides predictable lifetime performance in hot environments.
• High ripple acceptance across frequencies: Specified low‑ and high‑frequency ripple currents plus frequency coefficients allow straightforward ripple budgeting for both low‑ and high‑frequency circuits.
• Automotive‑grade reliability: AEC‑Q200 qualification supports use in applications that demand established automotive component standards.
• Compact radial form factor: φ10 × 25 mm can and standard 5 mm lead spacing balance board space efficiency with through‑hole mounting robustness.
• Regulatory compliance: RoHS compliant construction for environmental and supply‑chain requirements.
