UCY2D330MPD

The UCY2D330MPD is a radial lead aluminum electrolytic capacitor from Nichicon’s UCY series. It delivers a compact, polarized solution with a 33 µF capacitance and a 200 V rating for power filtering and energy storage in compact assemblies.

Designed for applications that demand high ripple tolerance and long operational life, this part is suitable for power supply and ballast applications and is qualified to AEC-Q200 for automotive use where specified.

Key Features

• Capacitance and Voltage — 33 µF nominal capacitance with a rated voltage of 200 V and capacitance tolerance of ±20% (–20%~20%).
• High ripple current — Low-frequency ripple current of 305 mA at 120 Hz and high-frequency ripple current of 610 mA at 100 kHz to support demanding power circuits.
• Low leakage and dissipation — Leakage current specified at 364 µA and tangent of loss angle (tan δ) max. 0.20 measured at 20°C, 120 Hz for predictable loss characteristics.
• Long life and wide temperature range — Rated life of 10,000 hours at 105°C and operating temperature from –40°C to +105°C for extended field reliability.
• Compact radial package — φ10 × 20 mm can with 5 mm lead spacing (±0.5 mm) for tightly spaced through-hole layouts; radial lead mounting for conventional assembly.
• Industry and environmental credentials — AEC-Q200 rating and RoHS compliant.
• Packaging and availability — Available in bulk (no terminal forming) and bag packing; status: mass production.

Typical Applications

• Automotive power systems — Used for filtering and smoothing in automotive power supplies and control modules where AEC-Q200 qualification is required.
• Power supplies — Bulk filtering and ripple suppression for DC power converters and auxiliary supplies, leveraging high ripple current capability and long life.
• Ballasts — Energy storage and ripple handling in ballast circuits as specified in the UCY series guidance.

Unique Advantages

• Measured ripple-handling capacity — Specified LF and HF ripple currents (305 mA @ 120 Hz, 610 mA @ 100 kHz) help ensure reliable performance under real-world AC and switching loads.
• Extended high-temperature endurance — 10,000 hours at 105°C provides predictable life for designs exposed to elevated ambient temperatures.
• Compact footprint — φ10 × 20 mm can with tight 5 mm lead spacing enables space-efficient through-hole designs.
• Predictable loss and leakage — Tan δ ≤ 0.20 (20°C, 120 Hz) and defined leakage current support stable circuit behavior and easier design verification.
• Automotive-capable qualification — AEC-Q200 rating supports use in vehicle-related power electronics where that qualification is required.
• Regulatory compliance — RoHS-compliant construction aligns with environmental requirements.
