UPW2G2R2MPD

The UPW2G2R2MPD is a miniature aluminum electrolytic capacitor in Nichicon’s UPW series, offered as a radial-lead, high-reliability component for power electronics. It delivers a 2.2 µF nominal capacitance at a 400 V rating in a compact φ10 × 16 mm can.

Designed for demanding environments, this part combines high-voltage capability, long endurance at elevated temperature, and AEC‑Q200 qualification for applications requiring rugged performance and reliable DC filtering or smoothing.

Key Features

• Capacitance & Voltage — 2.2 µF nominal capacitance with a rated voltage of 400 V and tolerance of -20% to +20%.
• Low-loss Characteristic — Tangent of loss angle (tanδ) specified at 0.25 (measured at 20°C, 120 Hz), indicating controlled dissipation for high-voltage filtering.
• Ripple Current Ratings — Low-frequency ripple current of 27 mA at 120 Hz and high-frequency ripple current of 43.2 mA at 10 kHz for AC ripple handling in power circuits.
• Leakage Current — Leakage current specified at 128 µA after rated voltage is applied, useful for precision bias and standby conditions.
• High-temperature Endurance — Rated life of 5000 hours at 105°C for long-term operation in elevated-temperature environments.
• Automotive-grade Qualification — AEC‑Q200 rating and explicit application for automotive electronics support use in robust systems.
• Package & Mounting — Radial-lead, polarized aluminum can (φ10 × 16 mm), lead spacing 5.0 mm (±0.5 mm), available in bulk or bag packing.
• Operating Range — Specified operating temperature from -40°C to +105°C to cover a broad set of environmental conditions.

Typical Applications

• Switching Power Supplies — Bulk decoupling and smoothing in high-voltage sections where compact, high‑voltage capacitors are required.
• Automotive Power Electronics — DC link and filtering in automotive power modules and converters, leveraging the AEC‑Q200 rating and 105°C endurance.
• High-voltage DC Conversion — Energy storage and ripple suppression in DC‑DC converters and high-voltage power circuits.

Unique Advantages

• High-voltage capability in a compact package — 400 V rating in a φ10 × 16 mm radial can keeps board space small while supporting high-voltage designs.
• Designed for sustained elevated-temperature service — 5000 hours life at 105°C provides predictable endurance for thermal-stressed applications.
• Automotive-capable qualification — AEC‑Q200 rating signals suitability for demanding vehicle electronics environments.
• Measured low-loss behavior — tanδ = 0.25 (20°C, 120 Hz) gives a quantifiable indicator of dissipation for thermal and ripple planning.
• Practical through-hole mounting — Radial-lead format with 5 mm lead spacing simplifies assembly and mechanical retention in power assemblies.
