The UKT1H472MRD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UKT series, engineered for general audio equipment and wide temperature range applications. It delivers 4700 µF capacitance at a 50 V rating in a compact φ20 × 40 mm can with 10 mm lead spacing.

Designed for demanding operating conditions, this part combines high capacitance, significant ripple-handling capability, and a broad temperature range to support power smoothing and decoupling in audio and related electronic systems.

Key Features

• Capacitance: 4.7 mF (4700 µF) with ±20% tolerance at 120 Hz, 20°C, providing substantial bulk energy storage for power supply smoothing and filtering.
• Voltage rating: 50 V rated voltage suitable for mid-voltage audio and power applications.
• Ripple current performance: 2100 mA (2.1 A) at 120 Hz and 2415 mA (2.415 A) at 10 kHz, supporting high ripple conditions and enabling robust AC handling.
• Loss characteristic (tan δ): 0.28 (DF) measured at 120 Hz, 20°C, indicating the capacitor's dissipation factor under standard test conditions.
• Leakage current: 705 µA specified, useful for evaluating standby losses and bias conditions in design.
• Operating temperature and lifetime: Rated for −55°C to +105°C with 1000 hours endurance at 105°C, supporting long-term operation in elevated-temperature environments.
• Package and mounting: Radial lead, can package sized φ20 × 40 mm with 10 mm lead spacing for through-hole assembly and secure mechanical mounting.
• Quality standard: Ratings include AEC-Q200, reflecting adherence to a recognized component qualification standard for passive components.
• Packaging options: Supplied in bulk (no terminal forming) or bag packing, accommodating typical procurement and assembly workflows.

Typical Applications

• Audio equipment: Bulk energy storage and smoothing for power supplies and amplifier rails in general audio systems.
• Power filtering: Decoupling and ripple suppression in mid-voltage power rails where high capacitance and significant ripple current capability are required.
• Industrial electronics: Through-hole radial mounting for robust mechanical retention and serviceable installations in equipment that operates across a wide temperature range.

Unique Advantages

• High energy density in a compact can: 4700 µF in a φ20 × 40 mm package provides large capacitance without large board area impact.
• Strong ripple handling: 2.1 A at 120 Hz and 2.415 A at 10 kHz supports sustained AC ripple currents common in power supply and amplifier applications.
• Wide operating temperature and proven endurance: −55°C to +105°C rating with 1000 hours at 105°C offers predictable performance in elevated-temperature environments.
• AEC-Q200 rating: Qualification per AEC-Q200 supports designs that require established passive component qualification practices.
• Through-hole radial format: Standard 10 mm lead spacing and can-style package simplify prototyping, repairability, and mounting robustness.
