UHD1E331MPD

The UHD1E331MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UHD series designed for general-purpose electronic designs requiring compact, high-ripple handling capacitors. It offers 330 µF capacitance at a 25 V rating in a small φ8×15L can with 3.5 mm lead spacing.

Part of the UHD family, this capacitor emphasizes low impedance in the high-frequency range and higher ripple capability, making it suitable for power filtering and decoupling in consumer and industrial electronics where reliable ripple tolerance and long endurance at elevated temperatures are required.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 25 V for bulk energy storage and smoothing in DC circuits.
• Low Impedance / High Ripple — Designed for lower impedance at high frequency; rated ripple currents of 696.5 mA at 120 Hz and 995 mA at 100 kHz support demanding ripple conditions.
• Endurance at Elevated Temperature — Specified life of 3000 hours at 105°C when subjected to rated voltage plus ripple current, providing predictable long-term performance under heat stress.
• Temperature Range — Operating range from −40°C to 105°C to cover a wide span of environmental conditions.
• Electrical Loss & Leakage — tan δ of 0.14 (measured at 20°C, 120 Hz) and leakage current of 82.5 µA, enabling stable performance in bias applications.
• Compact Radial Package — φ8×15L can with radial leads and 3.5 mm lead spacing for through-hole mounting where board space is limited.
• RoHS Compliant & Production Ready — RoHS-compliant construction, available in bulk/bag packing, and listed as in mass production.

Typical Applications

• Power supply smoothing: Bulk energy storage and output filtering for linear or switching regulators where 25 V rating and 330 µF capacitance are required.
• Decoupling in power rails: High-frequency ripple handling at up to 100 kHz makes this capacitor suitable for decoupling near power conversion stages.
• General-purpose electronics: Use in consumer and industrial boards that require reliable electrolytic capacitance with long endurance at high temperatures.

Unique Advantages

• High ripple tolerance: Rated ripple currents up to 995 mA at 100 kHz allow tighter regulation and reduced heating in high-frequency applications.
• Low high-frequency impedance: UHD series design targets reduced impedance at higher frequencies, improving transient response and filtering effectiveness.
• Extended high-temperature life: 3000 hours at 105°C gives predictable aging characteristics for designs exposed to elevated operating temperatures.
• Compact footprint: φ8×15L radial can delivers substantial capacitance in a small package for space-constrained through-hole assemblies.
• Stable leakage and loss characteristics: tan δ of 0.14 and low leakage current support stable behavior in biased circuits over temperature.
• Production-ready packaging: Available in bulk or bag packing and listed as mass production for straightforward procurement and assembly.
