UCY2H270MHD

The UCY2H270MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UCY series. It is a radial‑lead, polarized capacitor rated at 27 µF and 500 V designed for high-voltage, high-ripple applications.

Key strengths include long endurance at elevated temperature, high ripple-current capability across low and high frequencies, and AEC‑Q200 qualification for automotive use. Typical deployment areas include power supplies and ballast circuits where compact, high‑voltage filtering is required.

Key Features

• Capacitance & Voltage — Rated capacitance 27 µF with a nominal voltage of 500 V and a tolerance of −20% to +20%.
• High Ripple Current — Low-frequency ripple current 310 mA at 120 Hz and high-frequency ripple current 620 mA at 100 kHz, with frequency coefficients up to 2.00 at ≥100 kHz.
• Long Endurance — Rated life of 10,000 hours at +105°C under specified DC bias plus rated ripple current.
• Thermal Range — Operating temperature range from −40°C to +105°C for use in elevated-temperature environments.
• Low Loss & Leakage — Tangent of loss angle (tan δ) 0.24 measured at 20°C and 120 Hz; leakage current specified as 640 µA.
• Package & Mounting — Radial lead can (φ12.5 × 40 mm), lead spacing 5.0 mm (tolerance ±0.5 mm), supplied in bulk (no terminal forming) or bag packing.
• Qualification & Compliance — AEC‑Q200 qualified and RoHS compliant.

Typical Applications

• Automotive systems — Suitable for high-voltage filtering and energy buffering in automotive electronic modules where AEC‑Q200 qualification is required.
• Power supplies — Use for smoothing and ripple suppression in high-voltage power supply rails and DC link applications.
• Ballasts and lighting circuits — Designed for ballast applications where miniature, high‑voltage capacitors with sustained ripple capability are needed.

Unique Advantages

• 500 V rating for high-voltage circuits: Enables use in circuits requiring elevated DC voltage handling without series stacking.
• High ripple-handling across frequency: Specified ripple currents at 120 Hz and 100 kHz plus frequency coefficients support both low- and high-frequency filtering.
• Long life at elevated temperature: 10,000 hours at +105°C reduces replacement frequency in demanding environments.
• AEC‑Q200 qualified: Provides a documented qualification path for automotive designs that require standardized reliability testing.
• Compact radial package: φ12.5 × 40 mm can with 5 mm lead spacing fits space-constrained boards while retaining robust performance.
• Regulatory compliance: RoHS compliant to meet environmental directive requirements.
