ULD1V470MED

The ULD1V470MED is a polarized aluminum electrolytic capacitor from Nichicon's ULD series, provided in a radial-lead can for through-hole mounting. It delivers 47 µF capacitance at 35 V in a compact φ6.3 × 11 mm package with 2.5 mm lead spacing.

Designed for general-purpose power and lighting applications, this part combines long-life endurance and defined ripple handling to support smoothing and decoupling duties in compact power supplies and small electronic modules.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with tolerance of −20% to +20% at 120 Hz, rated for 35 V operation.
• Long-Life Endurance — Rated for 10,000 hours at 105°C under DC bias plus rated ripple current per the ULD series specification.
• Thermal Range — Operating temperature range −40°C to +105°C for use across a wide ambient span.
• Low Loss (tan δ) — tan δ = 0.22 measured at 20°C, 120 Hz, supporting reduced dissipation in AC conditions.
• Ripple Current Ratings — Specified low-frequency ripple current 147 mA at 120 Hz and high-frequency ripple current 210 mA at 100 kHz for mixed-frequency ripple environments.
• Leakage Current — Specified leakage current of 16.45 µA under rated conditions.
• Package & Mounting — Radial lead can, size φ6.3 × 11 mm, lead spacing 2.5 mm (±0.5 mm), supplied in bulk/bag packing.
• Compliance — RoHS compliant.

Typical Applications

• LED lighting power supplies — Provides smoothing and bulk capacitance in compact LED driver modules where long life at elevated temperature is required.
• General-purpose power supplies — Decoupling and smoothing for low-voltage rails in small form-factor converters and regulators.
• Consumer and industrial electronics — Board-level bulk capacitance in compact assemblies that require controlled leakage and specified ripple performance.

Unique Advantages

• Extended high-temperature life: 10,000 hours at 105°C specification supports longer service life in elevated-temperature applications.
• Compact, board-friendly footprint: φ6.3 × 11 mm can with 2.5 mm lead spacing saves PCB area while maintaining through-hole reliability.
• Measured low-loss behavior: tan δ = 0.22 at 120 Hz (20°C) helps limit heat generation under AC ripple conditions.
• Dual-frequency ripple handling: Specified ripple current at 120 Hz and 100 kHz provides defined performance for both low- and high-frequency ripple components.
• Controlled leakage: Leakage current value (16.45 µA) enables predictable bias characteristics for power designs.
• Environmentally compliant: RoHS compliance aligns with regulatory requirements for lead-free manufacturing.
