UPW2G220MHD

The UPW2G220MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPW series designed for radial-lead through-hole mounting. It delivers a 400 V rated voltage in a compact φ16 × 25 mm can, targeting power-filtering and DC bus applications where high voltage, predictable lifetime, and series-grade reliability are required.

Built for switching power supplies and demanding electrical environments, this polarized capacitor combines a controlled dissipation factor and rated ripple-current performance with an 8000-hour endurance at 105 °C to support robust long-term operation.

Key Features

• Rated Voltage — 400 V DC rating suitable for high-voltage DC bus and power-supply filtering applications.
• Capacitance and Tolerance — 22 µF capacitance with ±20% tolerance at 120 Hz, 20 °C, providing predictable bulk energy storage.
• Dissipation Factor (tan δ) — tan δ = 0.24 measured at 20 °C, 120 Hz, enabling calculation of ESR-related losses for thermal design.
• Ripple Current Performance — Low-frequency ripple current 110 mA at 120 Hz and high-frequency ripple current 176 mA at 10 kHz for effective AC ripple handling across switching and higher-frequency domains.
• Leakage Current — 452 µA leakage current specification to aid in power-budget and standby-loss calculations.
• High-Temperature Endurance — Rated lifetime of 8000 hours at 105 °C, supporting long-term reliability under elevated operating temperature.
• Package and Mounting — Radial lead, polarized can (φ16 × 25 mm) with 7.5 mm lead spacing (±0.5 mm) for straightforward through-hole assembly and secure mechanical mounting.
• Automotive-Grade Reliability — AEC-Q200 rating, qualifying the device for use in automotive applications that require component-level qualification.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit production handling preferences.

Typical Applications

• Switching Power Supplies — Bulk and output filtering where 400 V rating and defined ripple current capability improve voltage stability and reduce output ripple.
• Automotive Electronics — Power filtering and energy smoothing in automotive control modules, leveraging the AEC‑Q200 rating and 8000 h endurance at 105 °C.
• Industrial Power Systems — DC bus smoothing and transient suppression in industrial converters and power-conditioning equipment.

Unique Advantages

• High-Voltage Capability: 400 V rating lets designers use a single capacitor for higher DC bus and intermediate-voltage filtering tasks, simplifying BOM and layout.
• Space-Efficient Form Factor: φ16 × 25 mm can and radial-lead package provide a compact solution for constrained board layouts while maintaining required capacitance and voltage rating.
• Predictable Thermal and Lifetime Behavior: Specified 8000 h lifetime at 105 °C and measured tan δ allow engineers to model aging and thermal losses for reliable long-term designs.
• Ripple Performance Across Frequencies: Defined ripple current specs at 120 Hz and 10 kHz support designs spanning low-frequency bulk filtering to higher-frequency switching regimes.
• Automotive Qualification: AEC‑Q200 rating supports deployment in vehicle electronics where component-level qualification is necessary.
