UCY2W270MHD

The UCY2W270MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can package. It delivers 27 µF capacitance at a 450 V rating and is designed for applications that require high ripple-current capability and long operational life in compact axial footprints.

Designed for power electronics and automotive electronics, this radial-lead capacitor pairs a compact φ12.5 × 25 mm can with AEC-Q200 qualification and long endurance at elevated temperature, making it suitable for demanding power-supply and ballast environments.

Key Features

• Rated capacitance and tolerance — 27 µF nominal with tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• High voltage rating — 450 V rated voltage for high-voltage power electronics.
• High ripple-current capability — Specified low-frequency ripple current of 340 mA at 120 Hz and high-frequency ripple current of 680 mA at 100 kHz.
• Ripple current frequency scaling — Frequency coefficients defined (e.g., 0.80 at 50 Hz, 1.00 at 120 Hz, 1.60 at 1 kHz, 1.80 at 10 kHz, 2.00 at ≥100 kHz) to size ripple-current performance across operating frequencies.
• Endurance and temperature range — 12,000 hours rated life at 105°C; operating temperature range −40°C to +105°C.
• Electrical loss and leakage — Dissipation factor tanδ = 0.24 (measured at 20°C, 120 Hz) and specified leakage current of 586 µA.
• Package and mounting — Radial lead can, size φ12.5 × 25L with 5.0 mm lead spacing (lead-spacing tolerance ±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Reliability and compliance — AEC-Q200 rated and RoHS compliant for regulated-environment use.

Typical Applications

• Automotive power electronics — Energy-storage and filtering in vehicle power modules and electronic control units where AEC-Q200 qualification and high ripple capability are required.
• Power supplies — Bulk filtering and smoothing in high-voltage power-supply rails using the 450 V rating and 27 µF capacitance to stabilize DC outputs.
• Ballasts and lighting power — High-ripple and long-life characteristics make this capacitor suited for ballast circuits and other lighting power electronics.

Unique Advantages

• High-voltage, compact form factor: 450 V rating in a φ12.5 × 25 mm can enables high-voltage designs without a large board footprint.
• Designed for high ripple environments: Specified ripple currents at 120 Hz and 100 kHz plus published frequency coefficients allow engineers to predict thermal and lifetime behavior across frequencies.
• Long operational life at elevated temperature: 12,000 hours at 105°C supports robust thermal endurance in continuous-duty applications.
• Automotive-grade reliability: AEC-Q200 rating and RoHS compliance support use in regulated and high-reliability systems.
• Predictable electrical characteristics: Specified tanδ and leakage current values give clear parameters for ESR- and leakage-related design margins.
• Flexible packaging options: Available in bulk (no terminal forming) or bag packing to match assembly and procurement preferences.
