UFW1H470MED

The UFW1H470MED is a radial-lead aluminum electrolytic capacitor designed for audio equipment. It provides 47 µF capacitance at a 50 V rating in a compact φ6.3 × 11 mm can with 2.5 mm lead spacing.

Engineered for board-level audio applications, the part combines low loss (tanδ 0.12 at 20°C/120 Hz), defined ripple handling (150 mA at 120 Hz; 300 mA at 10 kHz), and a 2000-hour endurance rating at 85°C to deliver predictable performance over time.

Key Features

• Electrical Performance — 47 µF capacitance with a 50 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C).
• Low Dissipation — tanδ 0.12 (max.) at 20°C and 120 Hz for the 50 V rating, supporting low loss in audio frequency ranges.
• Ripple Current Capability — Rated ripple current of 150 mA at 120 Hz and 300 mA at 10 kHz; frequency coefficient for 33–47 µF parts scales from 1.00 at 120 Hz to 2.00 at 10 kHz.
• Leakage Current — Typical leakage current specified as 70.5 µA, supporting stable bias conditions after voltage application.
• Reliability & Endurance — Endurance rating of 2000 hours at 85°C with defined limits for capacitance change, tanδ, and leakage current after the test.
• Mechanical & Packaging — Radial-lead can (φ6.3 × 11 mm) with 2.5 mm lead spacing (±0.5 mm tolerance); supplied as bulk/bag packing (no terminal forming).
• Operating Temperature — Specified for −40°C to +85°C operation.

Typical Applications

• Audio equipment — Specified as part of the UFW series for audio equipment, suitable for circuits requiring stable 47 µF, 50 V electrolytic capacitors.
• Through-hole board assemblies — Compact radial-can form factor (φ6.3 × 11 mm) and 2.5 mm lead spacing suited to through-hole layouts in audio products and accessories.
• Frequency-dependent ripple environments — Frequency coefficient data (1.00 at 120 Hz, 2.00 at 10 kHz for 33–47 µF) aligns the part’s ripple ratings to both low- and high-frequency ripple conditions.

Unique Advantages

• Audio-focused specification: The UFW series is designated for audio equipment, and this part’s electrical characteristics and tanδ are specified with audio performance in mind.
• Predictable ripple performance: Clear ripple current ratings at 120 Hz and 10 kHz plus the documented frequency coefficients allow engineers to size the capacitor for both low- and high-frequency ripple loads.
• Compact radial form factor: φ6.3 × 11 mm can and 2.5 mm lead spacing provide a small footprint for through-hole designs where space is constrained.
• Long endurance at elevated temperature: 2000 hours at 85°C with specified post-test limits gives a defined expectation for life and stability under continuous elevated-temperature stress.
• Low loss for audio fidelity: tanδ 0.12 at 20°C/120 Hz supports reduced dissipation in audio-frequency circuits.
• Simple procurement and handling: Supplied in bulk/bag packing (no terminal forming) to support prototyping and manual assembly workflows.
