URS2A221MHD

The URS2A221MHD is a radial-lead aluminum electrolytic capacitor from Nichicon, specified at 220 µF and 100 V. It delivers a compact, low-profile form factor (φ16 × 15 mm) and is intended for general-purpose electronic power filtering and energy-storage applications.

Designed for board-level radial mounting, the part offers measurable low-loss performance (tanδ 0.08 at 20°C, 120 Hz), rated endurance of 2000 hours at 85°C, and defined ripple-current capability at both low and high frequencies—making it suitable for a range of industrial and consumer electronics designs.

Key Features

• Capacitance & Tolerance: 220 µF nominal with ±20% tolerance, enabling predictable bulk capacitance for power-supply decoupling and smoothing.
• Rated Voltage: 100 V DC rating for higher-voltage circuits where robust DC blocking and energy storage are required.
• Low-loss Performance: tanδ (DF) = 0.08 measured at 20°C, 120 Hz, supporting lower dissipation in filtering applications.
• Ripple Current Ratings: 620 mA at 120 Hz (low frequency) and 930 mA at 10 kHz (high frequency), providing defined performance for both mains-frequency and switching-frequency ripple conditions.
• Endurance & Temperature Range: 2000 hours at 85°C and an operating range of −40°C to +85°C for sustained performance in elevated-temperature environments.
• Leakage Current: Specified leakage current of 660 µA for predictable standby and bias behavior.
• Physical & Mounting: Radial-lead can package, size φ16 × 15 mm with 7.5 mm lead spacing (±0.5 mm), suitable for through-hole PCB layouts.
• Packaging & Production: Available in bulk (no terminal forming) or bag packing; product is in mass production by Nichicon.
• Polarized: Polar capacitor construction for DC applications where polarity is respected.

Typical Applications

• Power Supply Filtering: Bulk smoothing and ripple reduction in medium-voltage DC power supplies and linear regulators.
• DC/DC Converter Support: Energy storage and output filtering in switch-mode converter stages operating up to 100 V.
• Industrial Controls: Decoupling and transient absorption in control electronics where extended endurance at elevated temperature is required.
• General-Purpose Electronics: Circuit stabilization and charge storage in consumer and professional equipment that require a compact radial electrolytic solution.

Unique Advantages

• High Voltage Capability: 100 V rating allows use in higher-voltage DC rails without up-rating multiple lower-voltage parts.
• Defined Ripple Performance Across Frequencies: Separate ripple-current figures for 120 Hz and 10 kHz give designers clear guidance for both line-frequency and switching applications.
• Compact Low-Profile Footprint: φ16 × 15 mm can-style package saves board area while retaining substantial capacitance.
• Long Endurance at Elevated Temperature: 2000 hours at 85°C provides predictable lifetime behavior for sustained thermal environments.
• Predictable Loss and Leakage: Low tanδ and specified leakage current simplify thermal and standby-current budgeting in designs.
• Mass-Production Availability: Nichicon production status and common packaging options (bulk/bag) support volume procurement and assembly workflows.
