UBT1K330MPD8

The UBT1K330MPD8 from Nichicon is a radial-lead aluminum electrolytic capacitor specified for high-temperature operation. It provides 33 µF capacitance at an 80 V rating in a compact φ10 × 12.5 mm can with 5 mm lead spacing.

Designed for demanding electronics, this polarized capacitor targets applications that require elevated temperature endurance, controlled loss (tanδ), and measurable ripple-current handling. Its combination of 125°C operating capability, AEC-Q200 qualification, and proven endurance make it suitable for robust automotive and industrial power-filtering tasks.

Key Features

• Capacitance & Tolerance — 33 µF with a -20% to +20% tolerance at 120 Hz, 20°C for predictable charge storage and decoupling.
• High Voltage Rating — Rated at 80 V to support higher-voltage rail smoothing and energy-storage tasks.
• High-Temperature Endurance — Specified operating range from -40°C to +125°C and a rated life of 3000 hours at 125°C for sustained high-temperature operation.
• Low Loss — tanδ = 0.08 (measured at 20°C, 120 Hz), supporting efficient AC performance and lower dissipation in filtering roles.
• Ripple Current Capability — Low-frequency ripple current 321.6 mA (120 Hz) and high-frequency ripple current 480 mA (100 kHz) for effective suppression of AC ripple over a broad frequency range.
• Leakage Current — 79.2 µA (after 1 minute at rated voltage, 20°C) for controlled standby loss and dependable leakage behavior.
• Package & Mounting — Radial lead (can) package, φ10 × 12.5 mm, 5 mm lead spacing (±0.5 mm); supplied in Bulk (no terminal forming) or Bag packing.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant for automotive and regulated-environment use.
• Impedance — Specified impedance of 800 mΩ for predictable AC characteristics in filter and decoupling networks.

Typical Applications

• Automotive Electronics — Designed for ECU power rails, sensor modules and other on-vehicle electronics that require AEC-Q200 qualification and extended high-temperature endurance.
• Power Supply Filtering — Smoothing and bulk decoupling on DC–DC converters and power lines where 80 V rating and defined ripple-current performance are required.
• Industrial Control — Energy storage and ripple suppression in controllers and power modules operating in elevated-temperature environments.

Unique Advantages

• High-temperature capability: Rated to +125°C with a 3000-hour endurance at that temperature, enabling reliable operation in hot environments.
• AEC-Q200 qualification: Meets automotive electronic component qualification for designs that require industry-recognized robustness.
• Broad ripple-current performance: Defined ripple ratings at both low and high frequencies (321.6 mA at 120 Hz, 480 mA at 100 kHz) to cover switching and line-frequency noise suppression.
• Controlled leakage and loss: Low leakage current (79.2 µA) and tanδ = 0.08 at 120 Hz for efficient, predictable behavior in power circuits.
• Compact radial can: φ10 × 12.5 mm package with 5 mm lead spacing simplifies layout for through-hole assemblies while maintaining capacitance and voltage capability.
• Regulatory compliance: RoHS compliant for use in regulated product lines and supply chains.
