UFW2A470MPD

The UFW2A470MPD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UFW series, specified for audio equipment. It provides 47 µF capacitance at a 100 V rating in a compact φ10 × 12.5 mm can, optimized for designs that require reliable DC capacitance in audio-focused circuits.

Key attributes include a measured tanδ of 0.08 at 20°C/120 Hz, defined ripple current ratings across low and high frequencies, and a 2000-hour endurance at 85°C—offering predictable electrical performance and lifecycle data for design validation.

Key Features

• Electrical Rating — 47 µF capacitance with a 100 V rated voltage and ±20% tolerance, suitable where this specific capacitance and voltage combination is required.
• Audio-oriented Loss Characteristic — tanδ specified at 0.08 (max) at 20°C and 120 Hz for the 100 V rating, reflecting the UFW series' specification for audio applications.
• Defined Leakage Current — 141 µA leakage current as provided in the product specification for predictable bias behavior in circuits.
• Ripple Current Performance — 210 mA rated ripple current at 120 Hz and 420 mA at 10 kHz, enabling handling of both low-frequency and higher-frequency ripple within the stated limits.
• Temperature and Endurance — Rated operating temperature range of −40°C to +85°C with a 2000-hour endurance specification at 85°C for lifecycle planning.
• Radial Can Package — φ10 × 12.5 mm can size with 5 mm lead spacing and radial lead mounting; supplied bulk (no terminal forming) / bag packing for high-volume assembly and handling.
• Polarized Construction — Polarized aluminum electrolytic design, consistent with typical audio-series capacitor requirements.

Typical Applications

• Audio Equipment — Designed for use in audio equipment as specified by the UFW series; suitable where a 47 µF / 100 V polarized electrolytic capacitor is required.
• Audio Circuit Modules — Appropriate for modules and boards in audio-focused designs that reference the UFW series performance characteristics.
• Audio Product Prototyping and Production — Supplied in bulk/bag packing and in mass production status to support both development and volume manufacturing of audio products.

Unique Advantages

• Series Specified for Audio — Part of the UFW family, explicitly specified "for audio equipment," making selection and qualification straightforward for audio designers.
• Low Measured Loss at Audio Frequency — tanδ = 0.08 at 120 Hz and 20°C (100 V rating) provides a defined loss characteristic relevant to audio-frequency performance.
• Dual-Frequency Ripple Ratings — Explicit ripple current ratings at 120 Hz (210 mA) and 10 kHz (420 mA) support designs that must manage both low- and higher-frequency ripple components.
• Documented Endurance — 2000 hours at 85°C with post-test limits for capacitance, tanδ and leakage current, enabling predictable lifecycle assessment.
• Compact Radial Form Factor — φ10 × 12.5 mm can with 5 mm lead spacing fits space-constrained boards while offering through-hole reliability and simple mounting.
• Production-ready Supply — Listed as mass production status and available in bulk/bag packing for volume assembly workflows.
