UHE1E331MPD6

The UHE1E331MPD6 is a radial lead aluminum electrolytic capacitor from Nichicon's UHE series. It provides 330 µF capacitance at a 25 V rating in a compact φ10 × 12.5 mm can with 5 mm lead spacing, designed for general-purpose electronic applications.

As part of the UHE family, this capacitor offers low impedance, long endurance and RoHS compliance, delivering reliable smoothing and decoupling performance across an operating temperature range of −40 °C to +105 °C.

Key Features

• Capacitance & Voltage — 330 µF capacitance rated at 25 V for bulk energy storage and decoupling in 25 V systems.
• Low Impedance — Specified impedance of 320 mΩ to reduce voltage ripple and improve dynamic load response.
• Ripple Current Handling — Rated ripple current of 605.5 mA at 120 Hz and 865 mA at 10 kHz for effective AC ripple dissipation.
• Long Endurance — Rated life of 7000 hours at 105 °C, supporting extended operation in elevated-temperature environments.
• Temperature Range — Wide operating range from −40 °C to +105 °C for use across varied ambient conditions.
• Dielectric Loss (tan δ) — tan δ of 0.14 (measured at 20 °C, 120 Hz), indicating dissipation characteristics for design loss budgeting.
• Leakage Current — Specified leakage current of 82.5 µA for predictable standby and quiescent behavior.
• Package & Mounting — Radial lead (polar) can package, size φ10 × 12.5 mm with 5.0 mm lead spacing and 0.5 mm lead spacing tolerance; available in bulk or bag packing.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose power filtering — Bulk capacitance and low impedance make it suitable for smoothing DC rails and reducing ripple in 25 V circuits.
• Decoupling in embedded systems — Compact radial package and high ripple capability support local energy buffering on power boards and modules.
• Industrial electronics with elevated temperature requirements — 7000-hour endurance at 105 °C and a −40 °C to +105 °C range suit sustained operation in warm environments.

Unique Advantages

• Compact size with substantial capacitance — 330 µF in a φ10 × 12.5 mm can conserves board space while providing significant charge storage.
• Low impedance for improved performance — 320 mΩ impedance helps minimize voltage drop under dynamic loads and aids in ripple attenuation.
• High ripple current capability — Specified ripple currents at both low and high frequencies support designs with AC ripple across a broad frequency range.
• Long rated life at high temperature — 7000 hours at 105 °C provides predictable aging and end-of-life planning for long-running equipment.
• Polarized radial format for through-hole assemblies — Radial lead mounting simplifies hand-assembly and through-hole PCB designs with a 5 mm lead spacing.
• RoHS compliance and production availability — Environmentally compliant and listed as mass production for supply consistency.
