UKW1J471MHD

The UKW1J471MHD is a radial‑lead aluminum electrolytic capacitor in Nichicon's UKW series, specified at 470 µF and 63 V. It targets audio and AV applications where stable bulk capacitance, controlled loss, and reliable ripple handling are required.

Designed for through‑hole, radial mounting, this component delivers defined electrical characteristics across a –40°C to 85°C operating range and is manufactured for mass production with RoHS compliance and bag/bulk packing options.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a rated voltage of 63 V and a tolerance of ±20% (measured at 120 Hz, 20°C).
• Loss Factor (tan δ) — Low loss characteristic: tanδ max 0.10 at 63 V (120 Hz, 20°C), supporting stable performance in audio circuits.
• Ripple Current Performance — Handles 880 mA at 120 Hz (low frequency) and 1.32 A at 100 kHz (high frequency), enabling effective smoothing and decoupling across a range of ripple spectra.
• Leakage Current — Specified leakage current of 888.3 µA, useful for budgets in precision bias and power‑supply designs.
• Endurance & Temperature — Rated endurance of 2000 hours at 85°C; operating temperature range from –40°C to 85°C for reliable long‑term operation in typical AV environments.
• Package & Mounting — Radial, can‑style package with dimensions φ12.5 × 20 mm and 5.0 mm lead spacing (±0.5 mm); supplied bulk/no terminal forming or bag packed for PCB assembly.
• RoHS Compliant — Manufactured to meet RoHS requirements for regulatory compliance.

Typical Applications

• Audio power supplies — Bulk filtering and energy storage for amplifiers and preamplifier rails, leveraging high capacitance and controlled loss for clean audio delivery.
• AV equipment — Smoothing and decoupling in consumer and professional AV devices where the UKW series is specified for harmonious sound characteristics.
• General-purpose power filtering — Decoupling and ripple reduction on intermediate rails in bench and industrial equipment that use through‑hole components.

Unique Advantages

• Audio-oriented dielectric chemistry: Series-level electrolyte formulation focused on balanced sound quality, supporting AV and audio designs that prioritize sonic characteristics.
• High ripple capability across frequencies: Rated ripple currents at both low and high frequencies (880 mA at 120 Hz, 1.32 A at 100 kHz) allow a single part to address multiple filtering roles.
• Through‑hole robustness: Radial lead construction and a compact φ12.5×20 mm can enable easy integration into legacy PCBs and serviceable designs.
• Long endurance at elevated temperature: 2000 hours at 85°C endurance rating provides predictable life performance for designs expected to operate near the upper end of the temperature range.
• Regulatory readiness: RoHS compliance simplifies selection for markets requiring restricted‑substance conformity.

Why Choose UKW1J471MHD?

The UKW1J471MHD delivers a practical combination of bulk capacitance, defined loss characteristics, and frequency‑dependent ripple handling suited to audio and AV power stages. Its radial, can‑style package and standardized lead spacing make it straightforward to place into through‑hole designs that require serviceability and robust mechanical mounting.

This part is appropriate for engineers specifying reliable smoothing and decoupling capacitors for consumer and professional AV equipment, as well as other power‑filtering roles where a 470 µF/63 V polarized capacitor with a 2000‑hour endurance at 85°C is required.
