UKW1J472MRD

The UKW1J472MRD is a Nichicon UKW series aluminum electrolytic capacitor offering 4700 µF capacitance at 63 V in a radial-lead can. It is designed and specified for audio and AV equipment where high bulk capacitance and stable performance are required.

Built for continuous operation across a broad temperature range, this polarized radial capacitor provides long endurance and measurable electrical characteristics (tanδ, leakage, and ripple current) that support power smoothing, decoupling and energy storage in audio designs.

Key Features

• Capacitance & Voltage — 4700 µF (4.7 mF) rated at 63 V with ±20% tolerance for high bulk energy storage.
• Audio-Optimized Series — Part of the UKW series, specified "For Audio Equipment" and developed with an electrolyte tuned for sound quality and AV applications.
• Package & Mounting — Radial-lead can construction; case size φ12.5×20 mm with 1 cm lead spacing and package dimensions L: 5 × D: 2.2 cm for through-hole assemblies.
• Operational Range & Endurance — Rated for operation from −40°C to +85°C with endurance specified as 2000 hours at 85°C.
• Electrical Characteristics — Tangent of loss angle (tanδ) of 0.10 at the rated voltage; leakage current measured at 888.3 µA after 1 minute and 296.1 µA after 2 minutes (at 20°C after voltage application).
• Ripple Current — Listed rated ripple current of 880 mArms at 85°C/120 Hz; specification data also provide frequency-dependent ripple figures (examples include 3.4 A at 120 Hz and 3.91 A at 10 kHz).
• Compliance — RoHS compliant per product data.

Typical Applications

• Audio and AV Equipment — Bulk smoothing and decoupling in audio amplifiers and AV power supplies where series-level electrolyte tuning supports sound quality goals.
• Power Supply Smoothing — Energy storage and filtering for regulated supplies and power rails in consumer and professional audio electronics.
• Amplifier Energy Reservoir — Local energy buffering for power-stage demands in audio amplifier designs to support transient supply requirements.

Unique Advantages

• High Bulk Capacitance: 4700 µF at 63 V provides substantial energy storage for smoothing and decoupling in compact through-hole form factors.
• Audio-Focused Electrolyte: UKW series development emphasizes a balance of sound quality suitable for AV and audio applications.
• Endurance at Elevated Temperature: 2000 hours at 85°C gives a measurable lifetime metric for thermal-stressed applications.
• Wide Operating Temperature: −40°C to +85°C rating supports a broad range of operating environments for consumer and professional audio gear.
• Measured Electrical Data: Specified tanδ and leakage current measurements enable predictable design margining and QA verification.
• RoHS Compliant: Meets RoHS requirements for environmentally regulated designs.
