ULD1E470MDD

The ULD1E470MDD from Nichicon is a radial-lead aluminum electrolytic capacitor with a nominal capacitance of 47 µF and a rated voltage of 25 V. It belongs to the ULD series of miniature, long-life aluminum electrolytic capacitors designed for general-purpose power filtering and smoothing in through-hole PCB applications.

Key value comes from its long-life endurance (10,000 hours at 105°C), a broad operating temperature range of −40°C to 105°C, and compact radial can packaging (φ5×11L) suited to space-constrained designs. Note: this part is designated End Of Life.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a rated voltage of 25 V and capacitance tolerance of −20% to +20% for predictable decoupling and smoothing behavior.
• Long-Life Endurance — Rated for 10,000 hours at 105°C under specified load-life conditions, supporting extended operational duty in continuous-power applications.
• Temperature Range — Operates from −40°C to +105°C, enabling use across a wide range of ambient conditions.
• Low Loss Characteristic — Tangent of loss angle (tan δ) of 0.3 measured at 20°C, 120 Hz, supporting stable performance in low-frequency filtering.
• Ripple Current Handling — Specified low-frequency ripple current of 91 mA at 120 Hz and high-frequency ripple current of 130 mA at 100 kHz for effective ripple suppression in power-supply circuits.
• Leakage Current — Typical leakage current specified as 11.75 µA, aiding in predictable bias behavior after voltage application.
• Compact Radial Package — Small can size φ5 × 11L (D: 0.5 cm × L: 1.1 cm) with 2 mm lead spacing (±0.5 mm) for easy through-hole placement and wiring.
• RoHS Compliant — Conforms to RoHS requirements for restricted substances.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit different assembly workflows.

Typical Applications

• LED Lighting Power Supplies — Suited for filtering and smoothing in LED driver power-supply circuits where long operational life is required.
• General-Purpose Power Filtering — Through-hole smoothing and decoupling for consumer and industrial PCBs using radial-lead components.
• Embedded and Control Electronics — Local energy storage and ripple suppression in control boards and general-purpose circuits operating within −40°C to +105°C.

Unique Advantages

• Long Operational Life: 10,000-hour endurance at 105°C provides predictable lifetime performance for continuous-duty power applications.
• Space-Efficient Form Factor: Compact φ5×11L radial can and 2 mm lead spacing minimize board area while preserving through-hole robustness.
• Wide Temperature Range: Specified −40°C to +105°C operation supports use in varied environmental conditions without sacrificing performance.
• Measured Ripple Performance: Specified ripple currents at both low and high frequencies enable designers to size capacitors based on actual ripple-loading conditions.
• Known Loss and Leakage Metrics: Specified tan δ and leakage current values help ensure predictable behavior in low-frequency filtering and bias-sensitive circuits.
• RoHS Conformance: Compliant materials streamline regulatory compliance for many end products.
