UKL2A470MPD

The UKL2A470MPD is a Nichicon aluminum electrolytic capacitor in a radial-lead can designed for low leakage current applications. It provides 47 µF of capacitance at a 100 V rating in a compact φ10 × 20 mm package with 5 mm lead spacing.

Designed for audio and related electronic applications, this polarized capacitor combines low leakage, defined ripple-current capability, and a 2 000‑hour endurance at 85°C to support reliable power-supply and decoupling use in installed equipment.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance.
• Low Leakage Current — Specified leakage current of 9.4 µA, suitable where minimized leakage is required.
• Ripple Current Performance — Rated low-frequency ripple current 220 mA (120 Hz) and high-frequency ripple current 440 mA (10 kHz) to support supply smoothing and decoupling at multiple frequencies.
• Endurance and Temperature Range — Lifetime rated to 2 000 hours at 85°C with an operating temperature range of −40°C to +85°C.
• Package & Mounting — Radial lead, polarized aluminum can in a φ10 × 20 mm case, lead spacing 5 mm (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• Regulatory Compliance — RoHS‑compliant construction.

Typical Applications

• Audio power supply filtering — Low leakage and defined ripple-current ratings support filtering and smoothing in audio equipment power rails.
• Audio coupling and decoupling — Polarized electrolytic performance suitable for coupling/decoupling roles in audio circuitry where 47 µF/100 V is required.
• Consumer and pro audio electronics — Compact φ10 × 20 mm radial package for space-conscious audio designs demanding endurance at elevated temperatures.

Unique Advantages

• Low-leakage specification: 9.4 µA leakage current reduces bias loss and drift in circuits sensitive to leakage.
• Dual-frequency ripple ratings: Specified ripple currents at 120 Hz (220 mA) and 10 kHz (440 mA) make it easier to size capacitors for both low- and high-frequency ripple environments.
• Compact radial form factor: φ10 × 20 mm can with 5 mm lead spacing simplifies board layout in confined assemblies.
• High-voltage capability: 100 V rating enables use in higher-voltage portions of audio and related electronics without up-rating multiple lower-voltage devices.
• Proven endurance: 2 000 hours at 85°C supports reliable operation in equipment exposed to elevated operating temperatures.
• RoHS compliant: Aligns with environmental and regulatory requirements for modern electronic products.
