UHW1C222MHD

The UHW1C222MHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UHW series, offering 2200 µF capacitance at a 16 V rating. It is a miniature, high-ripple-current, polar electrolytic designed for general-purpose electronic applications that require bulk energy storage and power smoothing.

Key value comes from a compact φ12.5 × 20 mm can, low impedance, and high allowable ripple current—delivered with long-term endurance (10,000 hours at 105 °C) and RoHS compliance for reliable integration into production designs.

Key Features

• Electrical Capacity and Rating — 2200 µF capacitance rated at 16 V with capacitance tolerance ±20% (measured at 120 Hz, 20 °C).
• High Ripple Current Handling — Designed for demanding ripple environments: 1.95 A at 120 Hz and 2.6 A at 10 kHz (low- and high-frequency ripple current specifications).
• Low Impedance — Low impedance construction (51 mΩ) and reduced high-frequency impedance as indicated by the UHW series characteristics.
• Loss Factor — tan δ = 0.17 (measured at 20 °C, 120 Hz), suitable for stable AC performance under rated conditions.
• Robust Temperature and Lifetime — Operating temperature range −40 °C to +105 °C with endurance specified to 10,000 hours at 105 °C.
• Compact Radial Lead Package — φ12.5 × 20 mm can, radial-lead mounting with 5.0 mm lead spacing (±0.5 mm) and lead diameter 0.6 mm per series dimensional data.
• Polarized, Production-Ready Packaging — Polar type, available in bulk (no terminal forming) or bag packing; product status: mass production.
• Regulatory — RoHS compliant, per series declaration.

Typical Applications

• Power Supply Filtering — Bulk capacitance and high ripple-current ratings make this part suitable for smoothing and filtering stages in DC power supplies and converters.
• Decoupling in Power Electronics — Low impedance and defined tan δ provide stable decoupling for power rails in general-purpose electronic equipment.
• Energy Storage for Short-Term Loads — 2200 µF capacitance supports transient energy delivery in compact designs operating within the 16 V rating.

Unique Advantages

• High Ripple Capability: 1.95 A (120 Hz) and 2.6 A (10 kHz) ripple current ratings reduce temperature rise and improve performance in AC-stressed circuits.
• Compact Footprint: φ12.5 × 20 mm can packs 2200 µF into a small radial-lead package for space-constrained boards.
• Stable AC Characteristics: Low impedance (51 mΩ) and specified tan δ (0.17 at 20 °C, 120 Hz) help maintain consistent behavior across operating conditions.
• Long Endurance at Elevated Temperature: Rated 10,000 hours at 105 °C, supporting reliability requirements for designs operating near the upper temperature limit.
• Production-Ready Supply: Available in bulk or bag packing and listed as mass production status to support volume procurement and assembly.
• Regulatory Compliance: RoHS compliance enables use in assemblies requiring restricted-substance conformity.

Why Choose UHW1C222MHD?

The UHW1C222MHD balances high capacitance and ripple-current capability in a compact radial-lead can, making it well suited to general-purpose electronic systems that require reliable power smoothing and energy buffering at up to 16 V. Its low impedance and defined loss characteristics help preserve performance under AC ripple, while the 10,000-hour endurance at 105 °C provides predictable life for thermal-stressed applications.

This part is ideal for engineers specifying robust, production-ready electrolytic capacitors where board space, ripple handling, and long-term reliability are priorities. Backed by the Nichicon UHW series specifications, it delivers a verifiable combination of electrical performance and supply-chain readiness.
