UKW1H472MRD

The UKW1H472MRD is a Nichicon UKW-series aluminum electrolytic capacitor in a radial lead, can-style package. It provides 4.7 mF (4700 µF) capacitance at a 50 V rating with a polarization suitable for DC filtering and energy storage in audio and AV equipment.

Designed for audio-focused applications, the UKW series emphasizes sound quality through a specially developed electrolyte. This part combines high capacitance, measurable ripple handling at both low and high frequencies, and an operating range suitable for many consumer and professional AV power supply designs.

Key Features

• Capacitance & Voltage: 4700 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance for bulk energy storage and filtering.
• Audio-Optimized Electrolyte: UKW-series formulation aimed at delivering a harmonious balance of sound quality for AV and audio equipment.
• Radial Lead, Can Package: φ20 × 40 mm can with 10 mm lead spacing (±0.5 mm) for through-hole mounting and conventional assembly processes.
• Ripple Current Handling: Low-frequency ripple current 2.9 A (120 Hz) and high-frequency ripple current 3.335 A (10 kHz) to support power-supply smoothing at multiple bandwidths.
• Loss Tangent (tan δ): tan δ = 0.12 measured at 20°C, 120 Hz, at the 50 V rating, providing a quantifiable dissipation characteristic for circuit design.
• Endurance & Temperature Range: Rated for 2000 hours at 85°C with an operating temperature range of −40°C to +85°C for sustained performance under elevated temperatures.
• RoHS Compliant: Conforms to RoHS requirements for use in compliant assemblies.

Typical Applications

• Audio Amplifiers: Bulk filtering and smoothing in power supplies where large capacitance and audio-oriented electrolyte contribute to stable, low-noise operation.
• AV Equipment Power Rails: Decoupling and energy storage for consumer and professional AV devices that require sustained ripple handling at both low and high frequencies.
• General DC Power Supply Filtering: Bulk reservoir and smoothing capacitor in through-hole power supply designs where 4700 µF at 50 V is required.

Unique Advantages

• High Bulk Capacitance: 4700 µF provides substantial energy reserve for smoothing and transient support in power circuits.
• Dual-Band Ripple Capability: Specified ripple ratings at 120 Hz (2.9 A) and 10 kHz (3.335 A) allow designers to size the capacitor for both low-frequency rectifier ripple and higher-frequency switching artifacts.
• Audio-Focused Electrolyte: Series-level electrolyte development targets improved sonic characteristics for AV and audio applications where tonal balance matters.
• Durability at Elevated Temperature: 2000-hour endurance at 85°C supports reliable operation in sustained warm environments common to enclosed electronics.
• Through-Hole Convenience: Radial lead configuration and standard 10 mm lead spacing simplify assembly and replacement in traditional PCB layouts.
• Regulatory Compliance: RoHS compliance helps meet environmental and regulatory requirements for assembly into compliant products.
