UHD1A471MPD

The UHD1A471MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UHD series, designed for high ripple and low impedance performance in a compact φ8×11.5 mm can. It is a polarized 470 µF, 10 V unit with a −20%/+20% tolerance and is intended for general-purpose electronic designs that require reliable bulk capacitance in a small footprint.

Key value propositions include high ripple-current capability, a wide operating temperature range of −40°C to 105°C, and a 3000-hour endurance rating at 105°C for robust long-term operation in demanding environments.

Key Features

• Capacitance & Rated Voltage — 470 µF nominal capacitance with a 10 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C).
• Low Dissipation Factor — tanδ of 0.19 (max) at 20°C, 120 Hz, supporting efficient AC performance.
• High Ripple Current Capability — Rated ripple currents of 570 mA at 120 Hz and 760 mA at 100 kHz, backed by UHD series design for lower impedance at high frequency.
• Frequency Ripple Coefficients — Frequency coefficient characteristics for the 470 µF range (e.g., 0.75 at 120 Hz, 1.00 at 100 kHz) to size ripple margins across frequencies.
• Leakage Current — Specified leakage current of 47 µA (measured condition per product data).
• Thermal Endurance — Rated for operation from −40°C to +105°C with an endurance of 3000 hours at 105°C for the φ8 case size.
• Compact Radial Package — φ8 × 11.5 mm can with 3.5 mm lead spacing (±0.5 mm) and radial-lead mounting for through-hole PCB designs.
• Regulatory & Availability — RoHS compliant and available in bulk or bag packing; status: mass production.

Typical Applications

• General-purpose power filtering — Provides bulk capacitance and smoothing in general electronic circuits where a 470 µF, 10 V polarized capacitor is required.
• Decoupling for power rails — Radial-lead form factor suits through-hole power-rail decoupling and local energy storage on PCBs.
• High-frequency ripple environments — Designed for circuits that encounter ripple at both low and high frequencies, supported by the UHD series’ low-impedance characteristics.

Unique Advantages

• High ripple tolerance in a small can — Combines elevated ripple-current ratings with a compact φ8×11.5 mm package to save board space without sacrificing performance.
• Broad temperature range and endurance — −40°C to 105°C operation and 3000 hours at 105°C provide durability for designs subjected to prolonged thermal stress.
• Predictable AC behavior — Specified tanδ and frequency coefficients let engineers size capacitors for targeted impedance and ripple requirements across frequency bands.
• Clear electrical limits — Published ripple currents, leakage current, and tolerance support reliable selection and margining in power designs.
• Production-ready supply — RoHS compliance and mass-production status with bulk/bag packaging options simplify procurement and assembly planning.
