UHD1A222MHD

The UHD1A222MHD is a Nichicon UHD series aluminum electrolytic capacitor in a radial‑lead can, offering 2200 µF capacitance at 10 V with polarization. It is designed for general‑purpose electronic designs that require bulk capacitance combined with high ripple‑current handling and low impedance at higher frequencies.

Packaged in a compact φ12.5 × 20 mm can with 5 mm lead spacing and RoHS compliance, this part is supplied in bulk or bag packing and is available in mass production quantities.

Key Features

• Capacitance and Voltage: 2200 µF nominal capacitance at a rated voltage of 10 V, with tolerance of −20% to +20% for bulk energy storage needs.
• High ripple‑current capability: Rated ripple current of 1.888 A at 120 Hz and 2.36 A at 100 kHz, supporting demanding AC ripple conditions.
• Low impedance at high frequency: UHD series construction targets lower impedance in the high‑frequency range to improve performance in switching and high‑frequency applications.
• Endurance: Rated life of 5000 hours at 105 °C when subjected to DC bias plus rated ripple current, providing long operational life in elevated temperatures.
• Thermal and environmental range: Operating temperature range of −40 °C to +105 °C and RoHS compliance for regulatory compatibility.
• Physical and mounting: Radial lead can, size φ12.5 × 20 mm, lead spacing 5 mm (±0.5 mm), available in bulk (no terminal forming) or bag packing for flexible assembly handling.
• Leakage and dissipation: Leakage current specified at 220 µA and tangent of loss angle (tan δ) of 0.21 measured at 20 °C, 120 Hz for performance characterization.

Typical Applications

• General‑purpose electronics: Provides bulk capacitance and energy buffering for a wide range of electronic equipment classified as general purpose.
• Power‑supply smoothing: High ripple‑current capability and low high‑frequency impedance make it suitable for smoothing and filtering tasks where AC ripple must be managed.
• High‑frequency circuits: Designed for improved performance at higher frequencies, supporting applications with significant HF ripple components up to and beyond 100 kHz.

Unique Advantages

• High ripple handling: 2.36 A specified at 100 kHz delivers reliable ripple management in switching and high‑frequency environments.
• Compact radial package: φ12.5 × 20 mm can and 5 mm lead spacing provide a small footprint for designs with space constraints.
• Long life at elevated temperature: 5000 hours endurance at 105 °C gives predictable aging and replacement intervals for thermal stress conditions.
• Low high‑frequency impedance: UHD series construction reduces impedance at higher frequencies, improving decoupling and transient response where needed.
• Compliance and availability: RoHS compliant and in mass production, simplifying procurement and regulatory adherence.
• Practical leakage and loss characterization: Specified leakage current (220 µA) and tan δ (0.21 at 20 °C, 120 Hz) enable straightforward margin and thermal calculations.
