UCY2V180MPD

The UCY2V180MPD is a radial-lead, miniature aluminum electrolytic capacitor from Nichicon’s UCY series designed for high reliability applications. It delivers 18 µF capacitance at a 350 V rating in a compact φ10 × 20 mm can with radial leads and 5 mm lead spacing.

Targeted for demanding power applications, the UCY2V180MPD combines high ripple current capability, a wide operating temperature range (−40 °C to 105 °C), and a 10,000-hour life at 105 °C, making it suitable for power supplies, ballast circuits and automotive systems requiring AEC‑Q200 qualification and long-term stability.

Key Features

• Capacitance and Voltage — 18 µF nominal capacitance with a 350 V rated voltage and capacitance tolerance of −20% to +20%.
• High Ripple Current — Low-frequency ripple current 215 mA (120 Hz) and high-frequency ripple current 430 mA (100 kHz) for improved power-handling in switching and rectifier circuits.
• Long Life at Elevated Temperature — Rated endurance of 10,000 hours at 105 °C under the specified conditions for sustained reliability in high-temperature environments.
• Electrical Loss Characteristics — Tangent of loss angle (tan δ) up to 0.24 at 350 V (measured at 20 °C, 120 Hz), enabling predictable dissipation characteristics.
• Leakage Current — Specified leakage current of 352 µA, measured under rated conditions for predictable bias behavior.
• Compact Radial-Lead Package — φ10 × 20 mm can with 5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole assembly and easy hand or automated insertion.
• AEC‑Q200 Qualified — Qualification noted in the product specifications for applications requiring automotive-grade reliability.
• RoHS Compliant — Meets RoHS environmental requirements.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing to support production and prototyping workflows.

Typical Applications

• Power Supplies — Filtering and energy storage in AC/DC and DC/DC power conversion, benefiting from high ripple current capability and long life at 105 °C.
• Ballast Circuits — Suited for ballast and lamp-driving circuits where stable capacitance, high ripple tolerance and thermal endurance are required.
• Automotive Power Electronics — Designed for automotive use with AEC‑Q200 qualification, wide operating temperature range (−40 °C to 105 °C) and durable life rating.
• Industrial Control Equipment — Reliable decoupling and smoothing in industrial systems that demand extended endurance and predictable leakage and loss characteristics.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 215 mA (120 Hz) and 430 mA (100 kHz) support robust performance in switching environments and high-frequency applications.
• Extended operational lifetime: 10,000 hours at 105 °C provides long-term stability for designs exposed to sustained elevated temperatures.
• Automotive-grade reliability: AEC‑Q200 qualification in the specifications addresses application requirements for automotive and similarly demanding markets.
• Compact footprint: φ10 × 20 mm radial can and 5 mm lead spacing enable space-efficient board layouts while preserving through-hole mounting simplicity.
• Predictable electrical behavior: Specified tan δ (0.24 at 350 V) and defined leakage current (352 µA) make it easier to model dissipation and bias behavior in designs.
• Environmentally compliant: RoHS compliance supports regulatory requirements and eco-conscious product development.
