UCY2G120MPD

The UCY2G120MPD is a radial-lead aluminum electrolytic capacitor designed for high-ripple, long-life power applications. It is a 12 µF, 400 V polarized capacitor in a compact φ10 × 20 mm can with 5.0 mm lead spacing.

Engineered for demanding environments, this component targets automotive and power-supply applications where sustained ripple handling, extended endurance and wide operating temperature are required. Key value propositions include high ripple-current capability, 10,000-hour life at 105°C, and AEC-Q200 qualification.

Key Features

• Capacitance and Voltage — 12 µF nominal capacitance rated at 400 V DC with a capacitance tolerance of −20% to +20%.
• High Ripple Current — Low-frequency ripple current of 175 mA at 120 Hz and high-frequency ripple current of 350 mA at 100 kHz to support power-supply filtering and ballast loads.
• Long Endurance — Specified life of 10,000 hours at 105°C, providing predictable performance in elevated-temperature applications.
• Temperature Range — Operates from −40°C to +105°C to accommodate a wide range of environmental conditions.
• Low Leakage and Loss — Typical leakage current 292 µA and tan δ (DF) of 0.24 measured at 20°C, 120 Hz, enabling stable performance over time.
• Package and Mounting — Radial lead (through-hole) can in φ10 × 20 mm size with 5 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• Automotive-Grade Reliability — AEC-Q200 rated for use in automotive electronic systems and compliant with RoHS.

Typical Applications

• Automotive electronics — Power modules and control units that require AEC-Q200-qualified capacitors with long life and wide temperature range.
• Power supplies — Filtering and smoothing in DC power supplies where high ripple current capability and low leakage are important.
• Ballasts — Support for ballast applications requiring reliable ripple handling and endurance at elevated temperatures.

Unique Advantages

• Proven long-life performance: 10,000-hour endurance at 105°C ensures component longevity in continuous high-temperature operation.
• High ripple-handling capability: Rated ripple currents at both low and high frequencies provide flexibility across switching and line-frequency applications.
• Automotive-grade qualification: AEC-Q200 rating and −40°C to +105°C operating range meet rigorous automotive electronics requirements.
• Compact through-hole form factor: φ10 × 20 mm radial can with 5 mm lead spacing offers a space-efficient, serviceable solution for board-level power designs.
• Regulated dielectric characteristics: Specified tan δ and leakage current values measured at 20°C, 120 Hz give predictable electrical behavior for design calculations.
• RoHS compliant packaging options: Available in bulk or bag packing to suit production and assembly workflows while meeting environmental compliance.
