UKL1H470MPD

The UKL1H470MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKL series, designed for low leakage current and reliable performance in audio applications. It provides 47 µF capacitance at a 50 V rating in a compact φ8 × 11.5 mm can with 3.5 mm lead spacing.

This component targets audio and related electronic designs that require low self-discharge, defined ripple handling, and a compact radial-can package. Note: this product is scheduled for discontinuation and is not recommended for new designs.

Key Features

• Low Leakage Performance — Specified leakage current of 4.7 µA, supporting stable biasing and reduced self-discharge in low-current circuits.
• Electrical Rating — 47 µF capacitance with ±20% tolerance and a 50 V rated voltage for mid-voltage power and signal applications.
• Ripple Handling — Rated ripple current of 190 mA at 120 Hz (low frequency) and 380 mA at 10 kHz (high frequency), enabling use where AC ripple filtering is required.
• Temperature and Lifetime — Operates from −40°C to +85°C with an endurance rating of 2000 hours at 85°C.
• Package and Mounting — Radial lead (can) configuration with 3.5 mm lead spacing in a φ8 × 11.5 mm case, suitable for through-hole assembly.
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• Audio Equipment — Useful in audio circuitry where low leakage and controlled ripple performance preserve signal integrity and bias conditions.
• Power Filtering for Mid-Voltage Rails — Provides decoupling and smoothing for 50 V-rated supply rails in compact through-hole designs.
• Consumer and Industrial Electronics — Compact radial-can form factor fits a range of legacy and repair applications requiring defined lifetime and temperature performance.

Unique Advantages

• Low Self-Discharge: The 4.7 µA leakage specification helps maintain DC bias and reduces charge loss during idle periods.
• Defined Ripple Capability: Separate ripple ratings at 120 Hz and 10 kHz (190 mA and 380 mA) give designers measurable performance for both low- and high-frequency filtering.
• Compact Through-Hole Package: φ8 × 11.5 mm radial-can with 3.5 mm lead spacing supports easy insertion and secure mechanical mounting on PCBs.
• Temperature Endurance: Rated for −40°C to +85°C with 2000 hours endurance at 85°C, providing predictable behavior over the specified life test condition.
• Regulatory Compliance: RoHS compliance supports environmentally driven design requirements.

Why Choose UKL1H470MPD?

UKL1H470MPD is positioned as a compact, low-leakage aluminum electrolytic solution for audio and mid-voltage electronic designs that require stable biasing, predictable ripple handling, and a through-hole radial-can footprint. Its specification set — 47 µF at 50 V, low leakage, defined ripple currents, and a 2000-hour endurance at 85°C — makes it suitable for repair, replacement, and select production use where these exact characteristics are required.

Because this part is scheduled for discontinuation and is not recommended for new designs, it is especially relevant for customers maintaining existing product lines or sourcing like-for-like replacements where the UKL series specifications match the original design requirements.
