UCS2D330MPD

The UCS2D330MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UCS series designed for general-purpose power applications. It delivers 33 µF capacitance at a 200 V rated voltage in a compact φ10 × 20 mm can with polarized leads and a 5 mm lead spacing.

Engineered for high ripple environments and extended life, this part combines measurable low-frequency and high-frequency ripple handling with long endurance at elevated temperature, making it suitable for power supplies, ballast circuits and other industrial electronic equipment that require reliable DC filtering and energy buffering.

Key Features

• Capacitance & Tolerance — 33 µF with tolerance of -20% to +20% at 120 Hz, 20°C.
• Rated Voltage — 200 V DC rating for higher-voltage power rail applications.
• High Ripple Capability — Low-frequency ripple current 325 mA at 120 Hz and high-frequency ripple current 650 mA at 100 kHz, suitable for mixed-frequency filtering.
• Long Endurance — Rated life of 8000 hours at 105°C for consistent long-term performance in elevated-temperature environments.
• Loss Characteristics — tan δ (DF) = 0.20 measured at 20°C, 120 Hz, supporting predictable AC loss behavior.
• Leakage Current — Specified leakage current of 364 µA (measured after 1 minute at 20°C under rated voltage conditions as per series data).
• Compact Radial Package — φ10 × 20 mm can with 5 mm lead spacing and radial-lead mounting for through-hole assemblies.
• Operating Temperature — −40°C to +105°C operating range for a wide range of ambient conditions.
• Compliance & Packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing for production handling.

Typical Applications

• Power Supplies — DC filtering and bulk capacitance on 200 V rails where high ripple capability and long life are required.
• Ballast and Lamp Drivers — Energy buffering and ripple smoothing in ballast circuits referenced by the UCS series specification.
• Industrial Electronics — General-purpose decoupling and smoothing in control and power modules operating up to 105°C.

Unique Advantages

• High ripple tolerance: Dual ripple ratings (325 mA at 120 Hz and 650 mA at 100 kHz) allow the capacitor to handle both low- and high-frequency stress in mixed-source power environments.
• Extended high-temperature life: 8000 hours at 105°C provides predictable longevity for designs exposed to elevated ambient temperatures.
• Compact, through-hole form factor: The φ10 × 20 mm radial can and 5 mm lead spacing minimize board area while preserving through-hole mechanical robustness.
• Measured electrical stability: Specified tan δ and defined leakage current support repeatable AC loss and leakage behavior for reliable circuit simulation and margining.
• RoHS compliant production part: Meets RoHS requirements for lead-restricted designs and is available in production packaging formats for volume assembly.
