UHD1E471MPD

The UHD1E471MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UHD series, designed for general-purpose power applications that require high ripple capability and low impedance. This φ8×20 mm can delivers 470 µF nominal capacitance with ±20% tolerance at a 25 V rated voltage.

Engineered for durability and broad operating conditions, the UHD1E471MPD supports operation from −40°C to 105°C, a 3000 hour endurance at 105°C, and is available in bulk/bag packing for mass production supply.

Key Features

• High Capacitance — 470 µF nominal capacitance with ±20% tolerance at 120 Hz, supporting bulk energy storage and smoothing functions.
• Rated Voltage — 25 V rated voltage suitable for a wide range of low-voltage power rails and supply circuits.
• High Ripple Current Capability — Rated ripple current of 937.5 mA at 120 Hz and 1.25 A at 100 kHz, enabling effective handling of both low- and high-frequency ripple components.
• Low Leakage — Initial leakage current specified at 117.5 µA, reducing standby losses in DC circuits.
• Wide Temperature Range & Endurance — Operates from −40°C to 105°C with an endurance rating of 3000 hours at 105°C when subjected to rated DC bias plus rated ripple current.
• Radial Can Package — φ8×20 mm can with 3.5 mm lead spacing and radial lead mounting for through-hole PCB designs; available with bulk (no terminal forming) / bag packing.
• RoHS Compliant & Production Ready — Compliant with RoHS and listed as mass production status for supply continuity.

Typical Applications

• General Power Filtering — Use where 470 µF/25 V smoothing is required to reduce ripple on DC rails in general-purpose power circuits.
• Supply Decoupling — Effective for decoupling and bulk storage on low-voltage power supplies that demand high ripple current handling.
• High-Frequency Ripple Management — Suitable where low impedance at high frequency and elevated ripple currents are present, leveraging the UHD series’ low-impedance characteristics.

Unique Advantages

• High ripple tolerance: Explicit ripple ratings (937.5 mA @120 Hz, 1.25 A @100 kHz) allow designers to specify the part against measured ripple loads.
• Temperature and endurance validated: −40°C to 105°C operating range and 3000 h life at 105°C provide predictable behavior in long-running power designs.
• Compact radial form factor: φ8×20 mm can and 3.5 mm lead spacing conserve PCB area while offering through-hole reliability.
• Controlled leakage: Low initial leakage current (117.5 µA) minimizes leakage-related losses in standby and low-current states.
• RoHS compliant and production available: Meets RoHS requirements and is offered in mass production packaging options for procurement and manufacturing readiness.

Why Choose UHD1E471MPD?

The UHD1E471MPD balances high capacitance, strong ripple-current capability, and a compact radial package to meet common needs in general-purpose power and filtering designs. Its defined leakage, temperature rating, and endurance make it appropriate for designers who require predictable performance under continuous bias and ripple stress.

This part is a practical choice for engineers and buyers specifying a through-hole aluminum electrolytic capacitor for medium-voltage, medium-capacitance applications where long-term availability and RoHS compliance matter.
