URS1J221MHD

The URS1J221MHD is a radial-lead aluminum electrolytic capacitor offering 220 µF capacitance at a 63 V rating in a compact, low-profile φ12.5 × 12.5 mm can. It is designed for general-purpose electronic applications that require bulk capacitance, decoupling, and energy storage in space-constrained PCB designs.

Engineered for stability across a –40 °C to 85 °C operating range and a 2000-hour endurance at 85 °C, this part provides verifiable performance data for ripple handling, leakage, and dissipation factor to support reliable power designs.

Key Features

• Capacitance & Tolerance — 220 µF nominal capacitance with ±20% tolerance (120 Hz, 20 °C) for predictable bulk storage and decoupling behavior.
• Voltage Rating — Rated for 63 V operation to support medium-voltage rails and power supply sections.
• Compact Radial Package — φ12.5 × 12.5 mm can with 5.0 mm lead spacing (±0.5 mm) and radial-lead mounting for straightforward through-hole assembly and manual or wave soldering workflows.
• Ripple Current Capability — Low-frequency ripple current of 490 mA at 120 Hz and high-frequency ripple current of 735 mA at 10 kHz, enabling defined performance across typical and higher-frequency stress conditions.
• Dissipation Factor (tan δ) — tan δ = 0.10 measured at 20 °C, 120 Hz, supporting predictable loss and thermal behavior in AC-stressed circuits.
• Leakage Current — Specified leakage current of 415.8 µA, allowing designers to account for standby currents in their power budgets.
• Reliability / Endurance — Rated for 2000 hours at 85 °C with defined limits for capacitance change, dissipation factor, and leakage current after endurance testing.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit production and prototyping needs.

Typical Applications

• Power supply filtering — Provides bulk capacitance and ripple smoothing on 63 V rails where a 220 µF value is required.
• Decoupling and energy storage — Used for local energy buffering in general-purpose electronics to stabilize voltage during transient loads.
• Industrial and control electronics — Suitable for general-purpose circuitry that benefits from a compact, through-hole aluminum electrolytic with defined endurance at elevated temperature.

Unique Advantages

• Space-efficient form factor — φ12.5 × 12.5 mm low-profile can reduces board footprint while maintaining 220 µF capacitance.
• Clear electrical characterization — Specified tan δ, leakage current, and ripple current values allow designers to model thermal and electrical behavior accurately.
• Through-hole, serviceable mounting — Radial leads and standard 5 mm spacing simplify prototyping, repair, and manual assembly processes.
• Temperature-endurance specification — 2000-hour rating at 85 °C gives quantifiable lifetime expectations for sustained elevated-temperature use.
• Flexible supply packaging — Bulk or bag packing supports both small-batch prototyping and higher-volume production handling.
