UHW1A222MPD

The UHW1A222MPD is a miniature, radial‑lead aluminum electrolytic capacitor from Nichicon’s UHW series, engineered for general‑purpose electronic designs that require compact bulk capacitance and sustained ripple handling. It combines a 2.2 mF capacitance at 10 V with a small φ10×25 mm can and robust endurance characteristics.

Designed for applications demanding low impedance and high ripple capability in a compact package, the UHW1A222MPD delivers measurable performance benefits including low impedance (51 mΩ), high ripple current at both low and high frequencies, and 10 000‑hour endurance at 105 °C.

Key Features

• Capacitance & Tolerance — 2.2 mF (2,200 µF) with tolerance of −20% to +20%, suitable for bulk energy storage in compact circuits.
• Rated Voltage — 10 V nominal working voltage for low‑voltage power rails and decoupling tasks.
• Low Impedance — 51 mΩ DC impedance, supporting lower voltage drop and improved transient response in power applications.
• High Ripple Current — 2.175 A at 120 Hz (low frequency) and 2.9 A at 10 kHz (high frequency), enabling effective handling of both mains‑frequency and high‑frequency ripple currents.
• Loss Angle (tan δ) — tan δ ≈ 0.2 measured at 20 °C, 120 Hz, 10 V, providing a defined dissipation characteristic for thermal and loss calculations.
• Leakage Current — 220 µA specified, for predictable bias‑related leakage behavior in circuit designs.
• Temperature & Endurance — Operating range −40 °C to +105 °C with a rated lifetime of 10 000 hours at 105 °C.
• Package & Mounting — Radial lead, φ10×25 mm can with 5 mm lead spacing (±0.5 mm); available in bulk/bag packing for through‑hole assembly.
• Compliance — RoHS‑compliant construction.

Typical Applications

• General‑purpose power filtering — Bulk capacitance and low impedance make the UHW1A222MPD suitable for smoothing and decoupling on 10 V power rails in compact electronic products.
• Switching regulator support — High ripple current ratings at 120 Hz and 10 kHz provide reliable handling of both low‑frequency and high‑frequency ripple from switching supplies.
• Energy storage in compact designs — The φ10×25 mm package supplies significant capacitance where board space is constrained and through‑hole mounting is preferred.

Unique Advantages

• Compact bulk capacitance: 2.2 mF in a φ10×25 mm can reduces board area compared to larger capacitors while maintaining required charge storage.
• High ripple capability across frequencies: Rated ripple currents of 2.175 A (120 Hz) and 2.9 A (10 kHz) help minimize temperature rise and extend service life under ripple load.
• Low measured impedance: 51 mΩ impedance supports lower ESR‑related losses and improved transient performance in power distribution networks.
• Designed for extended high‑temperature use: 10 000‑hour endurance at 105 °C provides predictable lifetime performance in elevated operating temperatures.
• Through‑hole reliability and simple mounting: Radial leaded can with 5 mm lead spacing simplifies assembly and mechanical stability for discrete power sections.
• RoHS compliant: Meets current RoHS requirements for lead‑restricted applications.
