UPW1H221MPD

The UPW1H221MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPW series designed for high-reliability power applications. It delivers 220 µF at 50 V in a compact φ10 × 16 mm can with a 5 mm lead spacing.

Engineered for applications requiring low impedance and robust ripple handling, this part is specified for operation from −55 °C to +105 °C and rated for 5,000 hours at 105 °C, making it suitable for demanding power-filtering and supply-decoupling roles, including automotive electronics where AEC‑Q200 qualification is required.

Key Features

• Capacitance & Voltage — 220 µF capacitance rated at 50 V with ±20% tolerance (measured at 120 Hz, 20 °C), suitable for bulk filtering and decoupling.
• Low Impedance — Rated impedance of 238 mΩ supports lower voltage drop under high ripple conditions.
• High Ripple Current Capability — Low-frequency ripple current of 552.5 mA at 120 Hz and high-frequency ripple current of 850 mA at 10 kHz, enabling effective smoothing in switching supplies.
• Leakage Current — Specified leakage current of 330 µA after application of rated voltage, aiding predictable power loss budgeting.
• High Endurance — Life/endurance specification of 5,000 hours at 105 °C for long-term stability in elevated-temperature environments.
• Temperature Range — Wide operating range from −55 °C to +105 °C for deployment across harsh thermal conditions.
• Compact Radial Package — φ10 × 16 mm can with 5.0 mm lead spacing in a radial-lead form factor, available in bulk or bag packing.
• AEC‑Q200 Rated — Meets AEC‑Q200 requirements for applications that require automotive-grade component qualification.

Typical Applications

• Switching Power Supplies — Low impedance and high ripple-current capability make the UPW1H221MPD suitable for output filtering and energy storage in switching regulators.
• Automotive Electronics — AEC‑Q200 rating and broad temperature tolerance support use in vehicle control modules and in-vehicle power systems.
• DC‑DC Converters and Power Modules — Compact size and high endurance provide reliable decoupling and smoothing in compact power assemblies.

Unique Advantages

• Compact footprint with high capacitance — 220 µF in a φ10 × 16 mm can reduces board area for space-constrained designs.
• Balanced ripple handling across frequencies — Specified ripple currents at both low (120 Hz) and high (10 kHz) frequencies support versatile filtering roles in converters and supplies.
• Robust high-temperature endurance — 5,000-hour life at 105 °C provides longevity in thermal-stressed environments.
• Predictable electrical behavior — Defined impedance (238 mΩ) and leakage current (330 µA) make thermal and power-loss calculations straightforward.
• Automotive-capable qualification — AEC‑Q200 rating enables use in systems requiring automotive-grade components.
• Standard radial-lead form — 5.0 mm lead spacing and conventional radial can simplify through-hole assembly and prototyping.
