UCY2V270MPD

The UCY2V270MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UCY series, designed for compact power systems that require high ripple handling and long-term reliability. It is a polarized, miniature can-style capacitor with a rated capacitance of 27 µF and a nominal voltage of 350 V.

Targeted use cases include power-supply filtering, ballast and energy-storage applications in industrial and automotive systems. Key value propositions are its high ripple-current capability, long endurance at elevated temperature, and AEC-Q200 qualification for demanding environments.

Key Features

• Capacitance and Voltage — 27 µF rated capacitance with a 350 V rated voltage and ±20% tolerance at 20°C, 120 Hz.
• High ripple-current capability — Designed for demanding ripple environments with 305 mA at 120 Hz (low frequency) and 610 mA at 100 kHz (high frequency).
• Thermal endurance — Long life specification of 12,000 hours at +105°C under rated conditions, supporting extended operation in elevated-temperature applications.
• Electrical loss and leakage — Specified tan δ (loss tangent) of 0.24 at 20°C, 120 Hz, and a measured leakage current of 478 µA for this part.
• Compact radial package — φ10 × 30.5 mm can (L: 3.05 × D: 1.00 cm) with 5.0 mm lead spacing (±0.5 mm), suitable for through-hole mounting and secure mechanical retention.
• Automotive-capable qualification — AEC-Q200 rated, making it suitable for applications requiring recognized component-level reliability.
• Compliance and packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing. Status: Mass production.

Typical Applications

• Power supplies — Bulk energy storage and output filtering to smooth DC rails and support transient loads in industrial and automotive power systems.
• Ballasts and lighting drivers — Filtering and ripple handling for ballast circuits where high ripple current and elevated temperature endurance are required.
• Automotive electronics — Decoupling and energy buffering in vehicle power modules and auxiliary systems, leveraging AEC-Q200 qualification and −40°C to +105°C operating range.

Unique Advantages

• High ripple tolerance: Specified ripple currents at both low (305 mA at 120 Hz) and high frequency (610 mA at 100 kHz) enable robust filtering across a wide frequency range.
• Extended high-temperature life: 12,000-hour endurance at 105°C supports long service life in thermally challenging designs.
• Automotive-grade reliability: AEC-Q200 rating provides a recognized qualification level for demanding applications that require traceable reliability.
• Compact, serviceable form factor: Small φ10 can and radial leads with 5 mm spacing simplify integration into through-hole layouts while maintaining mechanical strength.
• Clear electrical characterization: Specified tan δ and leakage current values allow predictable loss and standby-current budgeting in design.
