UHV1A331MED

The UHV1A331MED is a radial-lead aluminum electrolytic capacitor designed for general-purpose electronic applications that require compact size and robust ripple handling. It belongs to Nichicon’s UHV series, offering lower impedance at higher frequencies and optimized ripple-current capability in a φ6.3 × 11 mm can.

Key performance attributes include 330 µF capacitance at 10 V, a low loss tangent (tanδ = 0.18 at 20°C, 120 Hz), rated ripple currents (275 mA at 120 Hz and 550 mA at 100 kHz), and an operating temperature range of −40°C to +105°C with a 5000 h endurance at 105°C.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance with a 10 V rating and ±20% tolerance, suitable for a wide range of low-voltage power designs.
• Low Loss Tangent — tanδ of 0.18 at 20°C and 120 Hz, providing reduced dissipation for improved AC performance.
• High Ripple Current Capability — 275 mA at 120 Hz (low frequency) and 550 mA at 100 kHz (high frequency), enabling effective smoothing and decoupling in noisy power circuits.
• Compact Radial Package — φ6.3 × 11 mm can with 2.5 mm lead spacing (±0.5 mm) in a radial-lead format for through-hole assembly and prototyping.
• Long Endurance — 5000 hours rated lifetime at 105°C under specified conditions, supporting extended reliability in elevated-temperature environments.
• Low Leakage — leakage current specified at 33 µA, minimizing standby losses and improving circuit stability.
• RoHS Compliant — meets RoHS directive requirements for environmentally conscious designs.
• Packaging — supplied in bulk (no terminal forming) / bag packing for volume assembly or manual use.

Typical Applications

• General-purpose electronics — Suitable for circuit filtering and energy storage where a compact, polarized electrolytic is required.
• Power circuits with high ripple — Use where elevated ripple-current handling at both low and high frequencies improves voltage stability.
• Through-hole prototypes and assemblies — Radial lead format and small can diameter fit dense PCB layouts and hand-assembled boards.

Unique Advantages

• High ripple capacity in a small footprint — Delivers 275 mA (120 Hz) and 550 mA (100 kHz) ripple handling from a φ6.3 × 11 mm package to save board space while maintaining performance.
• Predictable AC performance — Specified tanδ and impedance characteristics help engineers size capacitors for stable decoupling and filtering across frequency ranges.
• Extended high-temperature endurance — 5000 h at 105°C provides a measurable reliability baseline for designs exposed to elevated operating temperatures.
• Low leakage for power-sensitive designs — 33 µA leakage current reduces parasitic loss in standby and low-power states.
• Simple inventory and assembly — Radial-lead, bulk/bag packaging accommodates manual insertion and high-volume through-hole assembly workflows.
