UPW2A221MHD6

The UPW2A221MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPW series. It is a radial-lead, polarized can designed for power filtering and energy-storage roles with a rated capacitance of 220 µF and a 100 V voltage rating.

Targeted at switching power supplies and automotive power electronics, this part delivers low impedance, defined ripple-current capability, and long-term endurance for designs that require sustained performance at elevated temperatures.

Key Features

• Electrical Performance — 220 µF capacitance with tolerance ±20% and a 100 V rated voltage; impedance specified at 220 mΩ and tanδ 0.08 (measured at 20°C, 120 Hz).
• Ripple Current Handling — Rated low-frequency ripple current 552.5 mA at 120 Hz and high-frequency ripple current 850 mA at 10 kHz, supporting smoothing in switching converters and power rails.
• Leakage Current — Specified leakage current of 660 µA under rated conditions for predictable standby and power-down behavior.
• High-Temperature Endurance — Life rating of 8000 hours at 105°C, enabling reliable operation in thermally demanding environments.
• Robust Operating Range — Wide category temperature range from −55°C to +105°C for use across diverse ambient conditions.
• Radial Can Package — Compact φ18 × 20 mm can with 7.5 mm lead spacing (±0.5 mm) in a radial lead format; available in bulk or bag packing for flexible assembly workflows.
• Safety and Construction — Designed with a pressure relief vent and the UPW series’ low-impedance construction for dependable safety and performance under ripple stress.
• Automotive-Grade Reliability — AEC-Q200 rating for designs that require automotive-level qualification.

Typical Applications

• Switching Power Supplies — Bulk filtering and output smoothing where low impedance and defined ripple-current ratings improve regulator stability and transient response.
• Automotive Power Electronics — Power-rail decoupling and energy storage in automotive modules, leveraging the AEC-Q200 rating and 105°C endurance.
• DC–DC Converters and Power Modules — Local energy storage and ripple suppression in compact power assemblies that require a 100 V rating and a small radial footprint.

Unique Advantages

• High Voltage Capability — 100 V rating enables use where elevated bus voltages are present without upsizing the capacitor.
• Predictable Long-Term Performance — 8000 hours at 105°C life rating provides a clear reliability baseline for thermal-stressed designs.
• Measured Low Impedance — 220 mΩ impedance and tanδ 0.08 at 120 Hz translate to effective AC performance for filtering and smoothing tasks.
• Frequency-Responsive Ripple Design — Separate low- and high-frequency ripple current specifications (552.5 mA at 120 Hz / 850 mA at 10 kHz) support mixed-frequency power environments.
• Automotive Qualification — AEC-Q200 rating supports inclusion in automotive bill-of-materials for qualified subsystems.
• Compact Radial Format — φ18 × 20 mm can and 7.5 mm lead spacing allow dense board placement while preserving through-hole robustness.
