UBW1V221MPD

The UBW1V221MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UBW series. It delivers 220 µF nominal capacitance at a rated voltage of 35 V with polarized radial leads in a compact φ10 × 16 mm can.

Designed for demanding temperature environments and long life, this part targets automotive and industrial electronics where sustained performance at elevated temperatures and reliable ripple handling are required.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 35 V and tolerance of ±20% (±20% at 120 Hz, 20°C).
• Thermal Range & Endurance — Operating temperature range −55°C to +135°C and rated for 2000 hours endurance at 135°C (φ10 size lifecycle condition).
• Ripple Current Performance — Low-frequency ripple current 529.3 mA at 120 Hz and high-frequency ripple current 790 mA at 10 kHz, supporting power-conditioning applications across frequencies.
• Low Impedance — Specified impedance of 94 mΩ, enabling effective decoupling and energy storage in compact footprints.
• Leakage Current & Polarization — Measured leakage current of 231 µA and polarized construction suitable for DC applications requiring electrolytic capacitance.
• Mechanical & Packaging — Radial lead can (φ10 × 16 mm) with 5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing; mass production status.
• Quality & Qualification — Part of Nichicon’s UBW series and carries AEC-Q200 ratings appropriate for automotive-grade passive component requirements.

Typical Applications

• Automotive electronic modules — Suited for electronic control modules and other vehicle electronics requiring stable capacitance and long-term performance at temperatures up to 135°C.
• Power-supply decoupling and filtering — Provides bulk capacitance and low impedance with specified ripple current ratings for smoothing and transient support on DC power rails.
• High-temperature industrial electronics — Useful where extended endurance at elevated temperatures is necessary, leveraging the 2000-hour rating at 135°C for sustained operation.

Unique Advantages

• High-temperature endurance: Rated for operation to +135°C with 2000 hours endurance at that temperature for the φ10 size, enabling deployment in thermally demanding environments.
• Frequency-capable ripple handling: Separate ripple current specifications at 120 Hz and 10 kHz (529.3 mA and 790 mA) help designers account for both low- and high-frequency power disturbances.
• Compact, low-impedance form factor: φ10 × 16 mm can with 94 mΩ impedance provides significant capacitance density for space-constrained boards.
• AEC-Q200 qualification: Series-level rating supports use in automotive applications where component-level passive reliability is required.
• Manufacturing-ready packaging: Available in bulk or bag packing and listed as mass production, simplifying procurement for volume builds.
