UBW1C221MPD

The UBW1C221MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UBW series, designed for high-temperature, long-life applications. It delivers 220 µF capacitance at a 16 V rating with a polar aluminum-can construction and 5 mm lead spacing for through-hole designs.

Targeted for demanding environments, the device combines a wide operating temperature range and extended endurance to support power filtering, decoupling and energy-storage needs where elevated temperature and reliability are required.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance, rated for 16 V DC with ±20% tolerance at 120 Hz, 20°C.
• High-temperature operation — Specified operating temperature range of −55°C to +135°C, produced for use at +135°C as part of the UBW series.
• Long endurance — 2000 hours life/endurance rating at 135°C under rated bias and ripple conditions.
• Low loss (tan δ) — Maximum tanδ of 0.16 at 20°C and 120 Hz for the 16 V rating, supporting stable performance in filtering applications.
• Ripple current performance — 415.4 mA at 120 Hz (low frequency) and 620 mA at 10 kHz (high frequency), suitable for AC ripple damping and regulator output smoothing.
• Leakage and impedance — Specified leakage current of 105.6 µA and nominal impedance of 150 mΩ for predictable DC performance.
• Package & mounting — Radial lead, aluminum can package (size φ10 × 12.5L) with 5 mm lead spacing; supplied in bulk bag packing (no terminal forming) and in mass production.
• AEC-Q200 Rated — Designed to meet AEC-Q200 requirements for components in demanding environments.

Typical Applications

• Power supply filtering — Bulk and output smoothing for DC-DC converters and linear regulators operating at up to 16 V.
• Industrial power electronics — Decoupling and ripple suppression in controllers and power modules that require high-temperature endurance.
• Embedded and control systems — Energy storage and transient suppression on boards exposed to elevated ambient temperatures.

Unique Advantages

• High-temperature reliability: Endurance rating of 2000 hours at 135°C provides measurable lifecycle performance for hot environments.
• Designed for ripple-heavy circuits: Specified low- and high-frequency ripple current ratings (415.4 mA at 120 Hz, 620 mA at 10 kHz) enable use where AC loading is significant.
• Predictable electrical behavior: Low tanδ (0.16 at 120 Hz) and defined impedance (150 mΩ) simplify design margins for filtering and decoupling.
• Through-hole packaging simplicity: Radial-lead can with 5 mm lead spacing and φ10 × 12.5L size eases replacement and prototyping in legacy and industrial PCBs.
• AEC-Q200 qualification: Explicit AEC-Q200 rating supports selection for systems that require component-level automotive-grade screening.
