UPW2C221MHD

The UPW2C221MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPW series, featuring a 220 µF capacitance and a 160 V rated voltage. It is designed for power filtering and decoupling in switching power supplies and power electronics where a compact, high-voltage polarized aluminum capacitor is required.

Built for elevated-temperature operation and extended endurance, this part combines series-level design focus on low impedance and reliability with a compact φ18 × 35.5 mm can and standard radial mounting for through-hole assemblies.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 160 V rated voltage and ±20% tolerance, suitable for high-voltage filtering and energy storage in power circuits.
• Thermal Endurance — Rated operating temperature range −40°C to 105°C with a specified life of 8000 hours at 105°C, enabling long-term operation in warm environments.
• Ripple Current Capability — Low-frequency ripple current of 500 mA at 120 Hz and high-frequency ripple current of 800 mA at 10 kHz, supporting AC ripple handling across typical converter frequencies.
• Dissipation Factor — tanδ of 0.15 measured at 20°C and 120 Hz, indicating the capacitor’s loss characteristics under standard test conditions.
• Leakage Current — Specified leakage current of 1508 µA after voltage application, important for precision power budgeting and start-up behavior.
• Package & Mounting — Radial lead can, dimension φ18 × 35.5 mm with 7.5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for through-hole assembly.
• Series Design Focus — UPW series emphasizes miniature size, low impedance, and high reliability for switching power supplies, aligning this part to power electronics applications.
• Qualification — Rated to AEC-Q200, making it suitable for applications requiring that qualification level.

Typical Applications

• Switching Power Supplies — Bulk and output filtering in DC–DC converters and switched-mode power supplies where 160 V rating and low impedance behavior are required.
• Automotive Electronics — Power decoupling and smoothing in AEC-Q200-qualified automotive modules and control units operating up to 105°C.
• Industrial Power Modules — Energy buffering and ripple suppression in industrial converters and power distribution circuits operating under elevated temperature conditions.
• High-Voltage DC Systems — Local decoupling and transient absorption in medium-voltage power rails that require a 160 V rated polarized capacitor.

Unique Advantages

• High Voltage Capability: 160 V rating allows use in higher-voltage power rails without needing series capacitor stacks.
• Extended High-Temperature Life: 8000 hours at 105°C supports extended deployment in warm or thermally stressed environments.
• Broad Ripple Handling: Specified ripple current values at both low (120 Hz) and high (10 kHz) frequencies help ensure stability across converter switching regimes.
• Compact Through-Hole Form Factor: φ18 × 35.5 mm can with standard 7.5 mm lead spacing offers a small footprint for radial, through-hole board layouts.
• AEC-Q200 Rated: Qualification level appropriate for designs that require supplier-tested components for demanding applications.
