URS1H222MRD

The URS1H222MRD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s URS series. It provides 2200 µF capacitance at a 50 V rating in a compact φ20 × 25 mm can with 10 mm lead spacing, designed for general-purpose electronic applications that require bulk capacitance in a low-profile package.

Key value comes from its combination of high capacitance, rated voltage, and defined ripple-handling capability, together with a wide operating temperature range and a 2000-hour endurance at 85°C for stable long-term performance.

Key Features

• Capacitance & Rated Voltage — 2200 µF (±20%) rated at 50 V, providing substantial bulk energy storage for general-purpose designs.
• Radial Lead Package — Standard radial-lead can (φ20 × 25 mm) with 10.0 mm lead spacing (±0.5 mm) for through-hole mounting and straightforward PCB layout.
• Ripple Current Performance — Low-frequency ripple current of 1.75 A at 120 Hz and high-frequency ripple current of 2.013 A at 10 kHz, supporting demanding AC ripple conditions within the specified ratings.
• Loss Tangent (tan δ) — tan δ = 0.14 measured at 20°C, 120 Hz, suitable for assessing dissipation in design thermal budgets.
• Leakage Current — Specified leakage current of 3300 µA, enabling predictable post-charge behavior for power designs.
• Temperature & Endurance — Operating temperature range of −40°C to +85°C with an endurance rating of 2000 hours at 85°C under rated voltage.
• Packaging Options — Supplied in bulk or bag packing without terminal forming for flexible assembly handling.

Typical Applications

• General Purpose Electronics — Bulk energy storage and smoothing in consumer and industrial boards where a compact radial electrolytic is required.
• Power Supply Filtering — Use for rail smoothing and ripple absorption up to the 50 V rating, leveraging the listed ripple current capabilities.
• Embedded and Control Circuits — Local decoupling and energy reservoir functions in control and power delivery sections within the specified temperature range.

Unique Advantages

• High Bulk Capacitance in a Small Footprint — 2200 µF in a φ20 × 25 mm can allows designers to save board area without sacrificing energy storage.
• Defined Ripple Handling — Specified low- and high-frequency ripple current ratings let engineers size smoothing components with confidence.
• Predictable Dissipation — Measured tan δ at 20°C/120 Hz supports thermal and loss calculations during design validation.
• Wide Operating Temperature — −40°C to +85°C range covers many industrial and consumer environments while maintaining rated performance.
• Long Endurance — 2000 hours at 85°C under rated voltage provides known long-term behavior for lifecycle planning.
