UPM2W220MHD

The UPM2W220MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPM series, offering a 22 µF capacitance at a 450 V rating in a compact φ16 × 35.5 mm can. It is engineered for low impedance and high reliability in demanding power and control applications.

Key use cases include high-voltage power supplies, industrial and automotive electronics where high-temperature endurance, defined ripple handling and compact radial mounting are required. The part delivers measurable performance with specifications such as a 5000-hour life at 105°C, specified leakage and ripple current ratings, and AEC‑Q200 qualification.

Key Features

• Capacitance & Voltage — 22 µF rated capacitance with a 450 V working voltage for high-voltage DC-link and filtering applications.
• High-temperature Endurance — Rated life of 5000 hours at 105°C, supporting long-term operation under elevated ambient temperatures.
• Low Impedance Characteristics — Specified tangent of loss angle (tanδ) of 0.25 at 20°C, 120 Hz, indicating low-loss behavior for stable performance.
• Defined Ripple Handling — Low-frequency ripple current of 135 mA (120 Hz) and high-frequency ripple current of 216 mA (200 kHz) for reliable smoothing in switching and converter circuits.
• Leakage Current Specified — Leakage current of 496 µA, providing a measurable bound for design margining.
• Radial Can Package — φ16 × 35.5 mm can with 7.5 mm lead spacing (±0.5 mm) and radial-lead mounting suited for through-hole PCB assemblies; available in bulk or bag packing (no terminal forming).
• Compliance & Qualification — RoHS compliant and AEC‑Q200 qualified, supporting regulatory and reliability requirements.

Typical Applications

• High-voltage power supplies — DC-link and bulk filtering in switch-mode supplies that require a 450 V rating and defined ripple performance.
• Motor drives and inverters — Energy storage and smoothing in industrial drive circuitry where high-voltage capability and thermal endurance are needed.
• Automotive electronics — Systems that demand AEC‑Q200 qualified components for higher-reliability environments, leveraging the capacitor’s high-voltage rating and elevated-temperature life.
• Industrial control and power conversion — Filtering and decoupling in converters and control modules exposed to elevated temperatures and continuous ripple stress.

Unique Advantages

• High-voltage capability: 450 V rating enables use in applications requiring elevated DC-link or high-voltage filtering.
• Proven thermal endurance: 5000-hour life at 105°C supports extended operation in hot environments and reduces replacement frequency.
• Predictable loss and leakage: Specified tanδ and leakage current values allow engineers to model ESR-related losses and standby currents accurately.
• Ripple-rated for real-world use: Separate low- and high-frequency ripple current specifications help designers size capacitors for both mains-frequency and switching-frequency stress.
• Through-hole, serviceable package: Radial-lead can with standard lead spacing simplifies prototyping, assembly and field-repair workflows.
• Standards and compliance: RoHS compliance and AEC‑Q200 qualification provide a clearer path for regulatory and reliability planning.
