ULD2G4R7MPD

The ULD2G4R7MPD is a Nichicon ULD series radial-lead aluminum electrolytic capacitor offering 4.7 µF capacitance at a 400 V rating. It combines a compact φ10 × 12.5 mm can with radial leads and a 5 mm lead spacing for straightforward through‑hole mounting in power circuitry.

Designed for general-purpose power applications and LED lighting power supplies, this part provides long-life endurance at elevated temperature, RoHS compliance, and package options for bulk or bag packing to support production workflows.

Key Features

• Electrical Performance — 4.7 µF, 400 V: Rated capacitance of 4.7 µF with a voltage rating of 400 V suitable for higher-voltage DC filtering and energy-storage roles.
• Capacitance Tolerance and Loss: Capacitance tolerance −20% to +20% and tangent of loss angle (tanδ) of 0.24 measured at 20°C, 120 Hz, 400 V for predictable AC performance.
• Ripple Handling: Specified low-frequency ripple current of 61 mA (120 Hz) and high-frequency ripple current of 122 mA (100 kHz) for common power-supply ripple conditions.
• Leakage Current: Low leakage current specified at 175.2 µA to minimize steady-state losses in DC circuits.
• Long Life Reliability: Rated for 15,000 hours at 105°C (specific to the φ10 × 12.5L size), reflecting the ULD series long-life design intent.
• Mechanical and Mounting: Radial lead can (φ10 × 12.5 mm), 5 mm lead spacing (±0.5 mm tolerance) and polarized construction for easy through-hole assembly.
• Environmental Compliance and Packaging: RoHS compliant; available in bulk (no terminal forming) or bag packing to match manufacturing needs.

Typical Applications

• Power Supply Filtering: Bulk and decoupling capacitor for DC bus and secondary-side filtering in higher-voltage power supplies.
• LED Lighting Power Supplies: Designed within the ULD series for use in LED driver power circuits where long life at elevated temperature is required.
• General-Purpose Electronics: Through-hole, radial-lead format suits a wide range of general-purpose electronic designs requiring polarized energy storage.

Unique Advantages

• High Voltage Capability: 400 V rating enables use in higher-voltage DC circuits without needing larger, more complex capacitor arrangements.
• Compact, Serviceable Form Factor: φ10 × 12.5 mm can with 5 mm lead spacing provides a compact footprint for space-constrained through-hole assemblies.
• Long Operational Life at Elevated Temperature: 15,000-hour endurance at 105°C for the specified size supports reliable operation in demanding thermal environments.
• Measured AC Performance: Specified tanδ at 120 Hz and quantified ripple currents give designers clear parameters for AC loss and ripple budgeting.
• Low Standby Leakage: 175.2 µA leakage current reduces idle losses in DC systems, helping maintain efficiency over long deployments.
• Production-Ready Packaging: Bulk and bag packing options help streamline procurement and assembly for medium- to high-volume manufacturing.
