UHD1E470MDD

The UHD1E470MDD is a radial-lead aluminum electrolytic capacitor offering 47 µF capacitance at a 25 V rating. It is part of Nichicon’s UHD series, characterized by lower impedance at high frequency and engineered for high ripple current applications.

Designed for general-purpose electronics, this compact radial can delivers measurable benefits in power filtering and decoupling where low impedance, controlled loss (tan δ), and moderate ripple-handling capability are required within a small footprint.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 25 V rated voltage and a capacitance tolerance of −20% to +20%.
• Low Loss / High Frequency Performance — tan δ = 0.14 measured at 20°C, 120 Hz, and specified lower impedance in the UHD series for improved performance at higher frequencies.
• Ripple Current Capability — Specified ripple current of 175 mA at 120 Hz (low frequency) and 250 mA at 100 kHz (high frequency), supporting circuits with AC ripple demands.
• Leakage Current — Low leakage current rated at 11.75 µA, measured under stated conditions.
• Temperature and Endurance — Operating temperature range from −40°C to +105°C with an endurance/life rating of 2000 hours at 105°C.
• Compact Radial Package — Small can size φ5 × 11 mm length with radial lead spacing of 2.0 mm (lead spacing tolerance ±0.5 mm) for through-hole mounting and tight board layouts.
• RoHS Compliant — Meets RoHS directive requirements as stated for the UHD series.

Typical Applications

• Power Supply Filtering — Use in local smoothing and ripple suppression where the specified 175 mA (120 Hz) and 250 mA (100 kHz) ripple ratings and low impedance help stabilize supply rails.
• Decoupling on Compact Boards — Small φ5 × 11 mm radial package fits tight through-hole layouts while providing bulk capacitance for general-purpose decoupling.
• Embedded and Consumer Electronics — General-purpose capacitor for board-level power conditioning in consumer and embedded systems operating within −40°C to +105°C.

Unique Advantages

• Measurable High-Frequency Performance: Lower impedance at high frequency (UHD series characteristic) combined with a controlled tan δ supports improved AC performance in ripple-prone circuits.
• Specified Ripple Handling: Separate ripple current ratings for low (175 mA at 120 Hz) and high frequency (250 mA at 100 kHz) let designers match the part to the application's spectral ripple profile.
• Compact Through-Hole Footprint: The φ5 × 11 mm can and 2.0 mm lead spacing allow integration into dense PCB layouts while retaining through-hole robustness.
• Wide Operating Range and Defined Endurance: −40°C to +105°C operating range with 2000 hours endurance at 105°C provides a clear reliability envelope for thermal design and lifetime planning.
• Low Leakage: Leakage current of 11.75 µA supports applications where minimal standby current is important.
• Regulatory Compliance: RoHS compliance simplifies selection for markets and products where restricted substance compliance is required.
