UPM2A221MHD

The UPM2A221MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPM series, specified at 220 µF and 100 V. It is built for robust power-conditioning roles where high voltage handling, sustained ripple performance, and long-term reliability are required.

Engineered for demanding environments, this part offers low impedance (87 mΩ), a wide operating temperature range of −55°C to 105°C, AEC‑Q200 qualification, and a rated endurance of 5000 hours at 105°C—making it suitable for automotive and other high-reliability power applications.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 100 V and capacitance tolerance of −20% to +20%.
• Low Impedance — Specified impedance of 87 mΩ supports effective filtering and transient handling in power circuits.
• Ripple Current Capability — Handles 588 mA at 120 Hz (low frequency) and 1.05 A at 200 kHz (high frequency) to support both bulk and high-frequency decoupling.
• High Reliability Endurance — Rated for 5000 hours at 105°C under load, with defined limits for capacitance change, tan δ, and leakage current after endurance testing.
• Thermal & Environmental Ratings — Operating range from −55°C to 105°C and RoHS compliant construction.
• Form Factor & Mounting — Radial lead, can-style package with dimensions Ø12.5 × 35.5 mm and 5 mm lead spacing (±0.5 mm); available in bulk or bag packing.
• Loss Characteristics — tan δ of 0.08 measured at 20°C, 120 Hz, 100 V, supporting predictable dissipation behavior in designs.
• Leakage Current — Specified leakage current of 660 µA, enabling predictable bias characteristics after application of rated voltage.

Typical Applications

• Automotive Power Electronics — Suitable for ECU and body-control power rails where 100 V rating, AEC‑Q200 qualification, and 105°C endurance are required.
• DC‑DC Converter Filtering — Low impedance (87 mΩ) and high-frequency ripple capability (1.05 A at 200 kHz) support output smoothing and ripple suppression.
• Power Supply Bulk Storage — 220 µF capacitance and 100 V rating provide bulk energy storage and transient buffering in high-voltage power stages.

Unique Advantages

• Automotive-Grade Reliability: AEC‑Q200 qualification and a 5000‑hour load life at 105°C provide traceable reliability for vehicle electronics.
• Predictable Thermal Performance: Wide −55°C to 105°C operating range combined with low tan δ (0.08) gives consistent behavior across temperature extremes.
• Effective Ripple Management: Dual-frequency ripple ratings (588 mA at 120 Hz and 1.05 A at 200 kHz) reduce design uncertainty for both line-frequency and switching-frequency noise.
• Compact, Through-Hole Form Factor: Radial-lead can (Ø12.5 × 35.5 mm) with 5 mm lead spacing provides a durable, serviceable option for through-hole and hybrid assemblies.
• Regulatory Compliance: RoHS compliance supports equipment-level environmental requirements without additional qualification steps.
