UCY2V270MPD9

The UCY2V270MPD9 is a radial lead, polarized aluminum electrolytic capacitor from Nichicon's UCY series. It provides 27 µF capacitance at a 350 V rating in a compact φ10 × 25 mm can for use where high ripple tolerance and long operational life are required.

Designed for power supply and ballast use and specified for automotive applications, this part combines high ripple current capability, a wide operating temperature range (−40 °C to +105 °C) and a rated endurance of 12,000 hours at 105 °C to support reliable operation in demanding environments.

Key Features

• Capacitance and Voltage — 27 µF nominal capacitance with a rated voltage of 350 V and tolerance of −20% to +20%.
• High Ripple Current Capability — Low-frequency ripple current 255 mA at 120 Hz and high-frequency ripple capability of 510 mA at 100 kHz, supported by the UCY series frequency coefficients.
• Long Endurance — Rated life of 12,000 hours at +105 °C under DC bias plus rated ripple current; endurance criteria specify capacitance within ±20% and leakage current within initial limits after life test.
• Thermal Range — Operates from −40 °C to +105 °C for a wide range of thermal environments.
• Low Loss — Tangent of loss angle (tan δ) up to 0.24 (measured at 20 °C, 120 Hz for 350 V rating).
• Compact Radial Can — Radial lead package: φ10 mm diameter by 25 mm length, 5.0 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• Compliance and Qualification — RoHS compliant and AEC-Q200 qualified, suitable for automotive and other regulated applications.
• Leakage Current — Typical leakage current value indicated as 478 µA (measured conditions per product specification).

Typical Applications

• Power Supplies — Smoothing and filtering in switch-mode and linear power supplies where 350 V ratings and high ripple capability are needed.
• Ballast Circuits — Designed for ballast applications cited in the UCY series specification for reliable high-voltage performance.
• Automotive Power Electronics — Suitable for automotive power modules and control units where AEC-Q200 qualification and a wide temperature range are required.
• High-Ripple Environments — Applicable wherever sustained ripple currents and long life at elevated temperature are demanded by the application.

Unique Advantages

• High ripple tolerance: Specified low- and high-frequency ripple currents (255 mA @120 Hz and 510 mA @100 kHz) enable stable filtering under varying switching conditions.
• Long operational life: 12,000-hour endurance at 105 °C provides predictable aging characteristics for long-term deployments.
• AEC-Q200 qualification: The AEC-Q200 rating supports deployment in automotive and similarly regulated applications.
• Compact radial form factor: φ10 × 25 mm can with 5.0 mm lead spacing offers a small footprint for through-hole designs without sacrificing voltage rating.
• Reduced losses at operating frequency: tan δ specified at 0.24 (350 V, 120 Hz) helps manage dissipation in AC and ripple environments.
• Regulatory compliance: RoHS conformity for use in markets requiring lead-free materials.
