UPW2A221MHD

The UPW2A221MHD is a miniature, radial‑lead aluminum electrolytic capacitor from Nichicon’s UPW series, engineered for high reliability in demanding power applications. This 220 µF, 100 V polarized capacitor delivers low impedance and long endurance in a compact φ16 × 25 mm can package.

Designed for switching power supplies and automotive electronics, the part combines a wide operating temperature range (−55 °C to 105 °C) with an 8000‑hour endurance at 105 °C, making it suitable where sustained high‑temperature performance and durability are required.

Key Features

• Capacitance and Voltage — 220 µF rated capacitance with a 100 V rated voltage and ±20% tolerance, supporting higher‑voltage DC rails.
• Low Loss / Low Impedance — tanδ of 0.08 at 20 °C, 120 Hz and a specified impedance of 200 mΩ provide efficient energy handling and reduced power loss.
• Ripple Current Performance — Low‑frequency ripple current of 578.5 mA (120 Hz) and high‑frequency ripple current of 890 mA (10 kHz) for effective filtering in switching environments.
• High‑Temperature Endurance — Rated for 8000 hours at 105 °C, supporting long life under elevated operating temperatures.
• Robust Leakage and Polarization — Specified leakage current of 660 µA and polarized construction for DC power applications.
• Compact Radial Package — φ16 × 25 mm can with 7.5 mm lead spacing (±0.5 mm) and radial lead mounting for through‑hole assembly; available in bulk or bag packing.
• AEC‑Q200 Rated — Rated to AEC‑Q200, addressing reliability expectations for automotive and other high‑stress environments.

Typical Applications

• Switching Power Supplies — Filtering and smoothing on DC output rails where low impedance and high ripple handling are required.
• Automotive Electronics — Power decoupling and bulk energy storage in automotive modules, leveraging the AEC‑Q200 rating and extended temperature range.
• High‑Voltage DC Rail Support — Energy storage and transient suppression on 100 V DC rails in industrial or embedded power designs.

Unique Advantages

• High‑voltage capability: The 100 V rating enables use on higher DC rails without series arrangements.
• Long operational life: 8000 hours at 105 °C provides predictable endurance for designs exposed to sustained elevated temperatures.
• Effective ripple handling: Specified ripple currents at both low and high frequencies support filtering across switching frequencies common in modern power converters.
• Compact footprint: φ16 × 25 mm can minimizes board area while delivering substantial capacitance for bulk storage and decoupling.
• Automotive‑grade reliability: AEC‑Q200 rating aligns the component with demanding reliability requirements for vehicle electronics and other high‑stress systems.
• Ready for through‑hole assembly: Radial lead form with defined lead spacing and packaging options simplifies integration into existing PCB processes.
