ULD1J470MPD

The ULD1J470MPD is a radial lead aluminum electrolytic capacitor from Nichicon’s ULD series, offering 47 µF capacitance with a 63 V rated voltage in a compact can package. Designed for general-purpose power applications, it delivers long-life performance with a 10000-hour endurance rating at 105°C and a broad operating temperature range of -40°C to 105°C.

Its combination of compact size (φ8 × 11.5L), polarized radial-lead mounting, and measurable ripple/current characteristics makes it suited to power-supply filtering and decoupling roles, including LED lighting power modules referenced in the ULD series documentation.

Key Features

• Electrical — Capacitance & Voltage: 47 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Dissipation Factor: tanδ = 0.17 measured at 120 Hz, 20°C for the 63 V rating, supporting predictable AC loss behavior.
• Ripple Current Capability: Rated low-frequency ripple current of 168 mA at 120 Hz and high-frequency ripple current of 240 mA at 100 kHz, enabling AC ripple handling across typical power-supply frequencies.
• Leakage Current: Measured leakage current of 29.61 µA, specified per rated-voltage conditions.
• Long Life Endurance: Specified for 10000 hours at 105°C under rated conditions, in line with the ULD series long-life characteristics.
• Mechanical — Compact Radial Can: Compact φ8 × 11.5L form (L: 1.15 × D: 0.8 cm) with 3.5 mm lead spacing (±0.5 mm tolerance) for straightforward through-hole PCB mounting.
• Environmental Compliance: RoHS compliant.
• Mounting & Polarity: Radial lead mounting; polarized aluminum electrolytic construction for bulk capacitance applications.

Typical Applications

• LED lighting power supplies: Used for smoothing and decoupling in LED driver power stages, leveraging long-life and ripple current specifications cited for the ULD series.
• General-purpose power filtering: Bulk and decoupling capacitance in power-supply rails where 63 V rating and 47 µF are appropriate.
• Embedded and industrial electronics: Through-hole radial mounting for boards requiring serviceable, compact bulk capacitance with extended high-temperature endurance.

Unique Advantages

• Long-life specification: 10000-hour endurance at 105°C reduces replacement frequency in high-temperature operating environments.
• Clear ripple-handling data: Specified ripple currents at 120 Hz and 100 kHz provide designers with concrete targets for thermal and lifetime calculations.
• Low dissipation factor: tanδ = 0.17 at the part’s rating helps predict AC losses and thermal rise in power designs.
• Compact radial package: φ8 × 11.5L can and 3.5 mm lead spacing simplify placement in densely packed through-hole PCBs.
• Measured leakage specification: 29.61 µA leakage current figure facilitates bias and standby current budgeting in sensitive circuits.
• RoHS compliance: Meets environmental directive requirements for restricted substances.
