UKW1C223MRD

The UKW1C223MRD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKW series, engineered for audio and AV equipment. It provides high bulk capacitance (22,000 µF) at a rated voltage of 16 V and is optimized for use where large energy storage and ripple handling are required.

Designed with a focus on audio performance and long-term reliability, this component combines a wide operating temperature range with a 2,000-hour endurance rating at 85°C and measurable ripple-current capability across audio and higher frequencies.

Key Features

• High Capacitance — 22,000 µF nominal capacitance for substantial bulk energy storage and low-frequency smoothing in power rails.
• Rated Voltage & Tolerance — 16 V rated voltage with ±20% capacitance tolerance at 120 Hz, 20°C.
• Audio/AV-Optimized Electrolyte — Part of the UKW series developed for a “harmonious balance of sound quality,” specifically suited for audio and AV equipment.
• Ripple Current Performance — Supports 4.2 A at 120 Hz and 4.83 A at 10 kHz, enabling effective AC ripple handling across common audio frequencies.
• Thermal and Endurance Characteristics — Operating range from −40°C to +85°C with an endurance rating of 2,000 hours at 85°C.
• Radial Lead Package — φ22 × 50 mm can with 10 mm lead spacing and radial-lead mounting for through-hole PCB assembly.
• Polarized Construction — Polarized capacitor for DC power applications; marked with gold lettering on a black sleeve.
• RoHS Compliant — Meets RoHS directive requirements.

Typical Applications

• Audio Equipment — Bulk decoupling and power supply smoothing in amplifiers, preamplifiers, and other audio circuits where large capacitance supports stable low-frequency response.
• AV Systems — Energy storage and ripple suppression in consumer and professional AV gear, consistent with the UKW series’ AV focus.
• Power Supply Filtering — Smoothing and transient support on low-voltage rails where high capacitance and defined ripple current capability are required.

Unique Advantages

• Substantial Bulk Storage: 22,000 µF provides extended energy reserve for low-frequency smoothing and transient support.
• Audio-Focused Design: Series-specific electrolyte development targeting improved sonic balance, making it appropriate for AV and audio designs.
• Verified Ripple Capability: Specified ripple current ratings at 120 Hz and 10 kHz enable designers to size capacitors against known ripple loads.
• Wide Temperature Operation: −40°C to +85°C range supports deployment across varied thermal environments.
• Proven Endurance: 2,000 hours at 85°C endurance rating for predictable life performance in sustained elevated-temperature applications.
• Compliance and Marking: RoHS compliant and clearly marked with gold lettering on a black sleeve for traceability and assembly identification.
