URZ2A221MHD

The URZ2A221MHD is a radial lead aluminum electrolytic capacitor from Nichicon’s URZ series, offering a compact, low-profile can in a polarized through‑hole format. It combines a 220 µF capacitance with a 100 V rated voltage and is targeted at general-purpose power-electronics applications where high voltage, wide temperature range and robust ripple handling are required.

With an operating temperature range of −55°C to 105°C and an endurance rating of 1000 hours at 105°C, the URZ2A221MHD is designed for sustained performance in demanding thermal environments while maintaining low dissipation and controlled leakage.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance at a 100 V rated voltage for high-voltage smoothing and energy storage.
• Compact, Low‑Profile Radial Package — φ16 × 15 mm can with radial lead mounting and 7.5 mm lead spacing (±0.5 mm) for secure through‑hole installation.
• Wide Temperature Range & Endurance — Specified for −55°C to 105°C with a guaranteed life of 1000 hours at 105°C.
• Ripple Current Capability — Low‑frequency ripple current 440 mA (120 Hz) and high‑frequency ripple current 660 mA (10 kHz) to support power supply filtering across frequency ranges.
• Electrical Loss & Leakage — Dissipation factor tan δ of 0.08 (measured at 20°C, 120 Hz) and leakage current of 660 µA for controlled loss and standby current.
• Capacitance Tolerance & Polarization — ±20% tolerance at 120 Hz, 20°C; polarized device appropriate for DC electrolytic applications.
• Packaging Options — Available in bulk (no terminal forming) and bag packing to suit assembly and procurement preferences.

Typical Applications

• Power supply filtering — Bulk smoothing and decoupling in high‑voltage DC power supplies and regulators where 100 V capability is required.
• Power conversion — Energy storage and ripple suppression in DC‑DC converters and analog power stages operating within the specified temperature range.
• Industrial control electronics — Filtering and hold‑up in control and instrumentation equipment that demand long endurance at elevated temperatures.

Unique Advantages

• High voltage handling: 100 V rating enables use in higher‑voltage DC rails without series stacking.
• Compact footprint: φ16 × 15 mm can provides a low‑profile solution for through‑hole designs where board space is limited in height or diameter.
• Wide operating temperature: −55°C to 105°C supports applications across broad environmental conditions.
• Proven endurance: 1000 hours at 105°C gives predictable life performance for thermal stress conditions.
• Frequency‑responsive ripple capability: Specified ripple currents at 120 Hz (440 mA) and 10 kHz (660 mA) address both mains‑frequency and higher‑frequency switching environments.
• Low dissipation factor: tan δ = 0.08 (20°C, 120 Hz) contributes to efficient operation and reduced self‑heating under AC ripple.
