UKL1H471KHD

The UKL1H471KHD is a radial-lead aluminum electrolytic capacitor engineered for low leakage current and reliable ripple handling. With a rated capacitance of 470 µF and a 50 V rating, it is designed for applications where low DC leakage and sustained ripple performance are important.

Its radial can package (φ16 × 25L) and 7.5 mm lead spacing make it suitable for through-hole assemblies in audio-focused designs and other electronic equipment requiring polarized bulk capacitance and robust ripple endurance.

Key Features

• Capacitance and Voltage: 470 µF nominal capacitance with ±10% tolerance and a 50 V rated voltage for bulk energy storage and decoupling in polarized circuits.
• Low Leakage Current: Specified leakage current of 47 µA, minimizing DC bias loss and drift in long-term applications.
• Ripple Current Performance: Low-frequency ripple capability of 760 mA (at 120 Hz) and high-frequency ripple capability of 1.14 A (at 10 kHz) for effective smoothing across audio and power frequencies.
• Endurance: Rated for 2000 hours at 85°C, providing predictable life performance under elevated operating temperatures.
• Temperature Range: Operates from −40°C to +85°C to cover a broad range of environmental conditions.
• Mechanical and Mounting: Radial lead, polarized can in φ16 × 25L size with 7.5 mm lead spacing (±0.5 mm), available in bulk or bag packing for through-hole assembly.
• RoHS Compliant: Conforms to RoHS requirements for lead-free manufacturing processes.

Typical Applications

• Audio Power Supply Filtering: Bulk capacitance and high ripple-handling capability make it suitable for smoothing power rails in audio amplifiers and preamplifiers.
• Audio Signal Power Stages: Low leakage helps maintain bias stability in amplifier stages and other polarized audio circuits.
• Through-Hole Electronic Equipment: Radial-lead form factor simplifies assembly for repairable or assembly-line through-hole audio and signal-processing equipment.

Unique Advantages

• Reduced DC Bias Loss: Low leakage current (47 µA) helps preserve circuit bias and reduces drift over time.
• Broad Ripple Handling: Specified ripple ratings at both low (760 mA at 120 Hz) and high (1.14 A at 10 kHz) frequencies support stable performance across audio and switching environments.
• Predictable Thermal Endurance: 2000-hour rating at 85°C provides a clear baseline for lifetime calculations in thermally stressed applications.
• Compact Through-Hole Package: φ16 × 25L radial can with 7.5 mm lead spacing balances capacitance density with ease of PCB placement and assembly.
• Regulatory Compliance: RoHS compliance supports lead‑free manufacturing requirements.
