UKA0J471MPD

The UKA0J471MPD is an aluminum electrolytic capacitor from Nichicon's UKA series, engineered specifically for high-grade audio equipment. It is a polarized, radial-lead can with a rated capacitance of 470 µF and a rated voltage of 6.3 V.

Designed for demanding environments, the part delivers a wide operating temperature range of –55°C to +105°C, AEC-Q200 reliability, and a 2000 hour endurance at 105°C—making it suitable for audio designs that require stable capacitance, controlled loss characteristics, and reliable ripple handling.

Key Features

• Capacitance & Voltage: 470 µF nominal capacitance at a rated voltage of 6.3 V with ±20% tolerance (120 Hz, 20°C).
• Wide Temperature Range & Endurance: Rated for –55°C to +105°C with an endurance specification of 2000 hours at 105°C when rated voltage is applied.
• Low Loss (Audio Focus): Tangent of loss angle (tan δ) of 0.30 at 6.3 V, 120 Hz, 20°C—supporting low-loss performance appropriate for audio circuitry.
• Controlled Leakage Current: Leakage current specified at 88.83 µA after 1 minute and 29.61 µA after 2 minutes (at 20°C), meeting JIS-style leakage limits for the given capacitance and voltage.
• Ripple Handling & Frequency Response: Rated ripple current of 270 mA (105°C/120 Hz); frequency coefficients for this capacitance class increase ripple capability at higher frequencies—equating to 405 mA at 10 kHz.
• Compact Radial Can Package: Case size φ8 × 11.5 mm (L: 1.15 × D: 0.8 cm) with 3.5 mm lead spacing and 0.6 mm lead diameter for through-hole, radial-lead mounting.
• Manufacturing Qualification: AEC-Q200 listed in the product specifications, indicating supplier-level reliability screening for passive components.

Typical Applications

• High-Grade Audio Equipment: Bulk capacitance and low-loss characteristics for power supply smoothing and signal-path support in premium audio designs.
• Audio Power Supply Decoupling: Handles ripple current across audible and higher frequencies to stabilize supply rails in amplifiers and preamplifiers.
• Compact Audio Modules: Small φ8 × 11.5 mm radial can enables use in compact PCB layouts where reliable capacitance is required.

Unique Advantages

• Audio-Optimized Electricals: 470 µF capacitance and tan δ of 0.30 at 6.3 V provide a balance of bulk energy storage and controlled loss for audio fidelity considerations.
• Wide Operating Temperature: –55°C to +105°C rating allows the capacitor to maintain performance across broad thermal environments common in pro audio and industrial audio equipment.
• High Ripple Capability: 270 mA rated ripple at 120 Hz with a frequency coefficient enabling up to 405 mA at 10 kHz supports both low-frequency smoothing and higher-frequency decoupling.
• Proven Endurance: 2000 hours at 105°C endurance specification ensures long-term stability of capacitance, tan δ, and leakage characteristics under elevated temperature stress.
• Compact, Easy-to-Use Form Factor: Radial can (φ8 × 11.5 mm) with 3.5 mm lead spacing and 0.6 mm leads simplifies through-hole assembly and mechanical retention on PCBs.
• AEC-Q200 Reliability Screening: Inclusion of AEC-Q200 in the specifications supports selection for designs where supplier-level passive component reliability data is required.
