UKW1A223MRD

The UKW1A223MRD is an aluminum electrolytic capacitor in a radial‑lead can designed for audio equipment. Built as part of Nichicon’s UKW series, it leverages a specially developed electrolyte to support a harmonious balance of sound quality and is RoHS compliant.

This radial‑lead, polarized capacitor is intended for use in AV and audio applications where bulk capacitance, ripple handling, and stable operation across a wide temperature range are required.

Key Features

• Capacitance — 22 mF nominal capacitance for audio power supply smoothing and decoupling.
• Rated Voltage — 10 V working voltage suitable for low‑voltage audio rails.
• Audio‑focused Electrolyte — Series development emphasizes a balanced sound character, targeting AV and audio equipment.
• Radial Lead, Can Package — Through‑hole radial lead mounting with a compact can package and 1 cm lead spacing for straightforward PCB placement.
• Operating Temperature — Specified for −40°C to +85°C to cover typical consumer and professional AV environments.
• Endurance — Rated for 2000 hours at 85°C under rated voltage, meeting the UKW series endurance criteria.
• Ripple Current Capability — 3.7 A at 120 Hz (low frequency) and 4.255 A at 10 kHz (high frequency) to handle both mains‑frequency and higher‑frequency ripple in audio power supplies.
• Polarized — Intended for correct polarity installation in DC audio circuits and power rails.
• RoHS Compliant — Meets RoHS requirements as specified for the UKW series.

Typical Applications

• Audio Equipment — Bulk filtering and decoupling in amplifiers, preamplifiers, and power supply stages to support consistent audio performance.
• AV Receivers and Home Theater — Energy storage and ripple suppression for low‑voltage audio rails in consumer AV systems.
• Professional Audio Electronics — Power smoothing in mixers, processors, and other rack‑mount gear where sustained ripple handling and endurance are required.

Unique Advantages

• Designed for audio fidelity — The UKW series’ electrolyte development targets a harmonious balance of sound quality, making this part suited to AV and audio applications.
• High bulk capacitance in a compact radial can — 22 mF capacitance in a radial package provides substantial energy storage while remaining easy to mount on through‑hole PCBs.
• Dual‑frequency ripple handling — Specified ripple current values at 120 Hz and 10 kHz demonstrate capability across low and high ripple frequencies common in audio power rails.
• Operational robustness — Rated for −40°C to +85°C and endurance of 2000 hours at 85°C for predictable performance over time.
• RoHS compliance — Supports regulatory requirements for lead‑free assemblies.
