UHE1V332MHD6

The UHE1V332MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UHE series. It is a polarized, radial-lead capacitor specified at 3300 µF and 35 V, designed for general-purpose electronic applications that require low impedance, elevated ripple handling and extended endurance at high temperature.

Key value propositions include low impedance (38 mΩ), high ripple-current capability (3.376 A at 120 Hz, 4.22 A at 10 kHz), and a 10,000-hour rated life at 105°C, all in a compact φ18 × 35.5 mm can with 7.5 mm lead spacing.

Key Features

• Capacitance & Rated Voltage — 3300 µF (3.3 mF) nominal capacitance with a rated voltage of 35 V and a tolerance of -20% to +20%.
• Low Impedance — Typical impedance of 38 mΩ supports fast charge/discharge and effective decoupling in power circuits.
• High Ripple Current Capability — Low-frequency ripple current of 3.376 A at 120 Hz and high-frequency ripple current of 4.22 A at 10 kHz for demanding power-conditioning tasks.
• Long Endurance at Elevated Temperature — Rated for 10,000 hours at 105°C under the series endurance specification for 16–100 V units, supporting long-term operation in hot environments.
• Temperature Range — Operates from -40°C to +105°C to cover a wide range of environmental conditions.
• Physical & Mounting — Radial lead can configuration, size φ18 × 35.5 mm, lead spacing 7.5 mm (±0.5 mm), available in bulk or bag packing.
• Loss and Leakage Characteristics — Dissipation factor (tanδ) of 0.16 (20°C, 120 Hz) and leakage current approximately 1155 µA as specified for this part.
• RoHS Compliant — Manufactured in compliance with RoHS requirements.

Typical Applications

• General-purpose power filtering — Use where a 3300 µF, 35 V polarized capacitor with low impedance and substantial ripple-current rating is required for smoothing and decoupling.
• Power-supply reservoir — Acts as bulk energy storage in power rails that need high ripple-handling and long-term stability at elevated temperatures.
• Industrial and commercial electronics — Suitable for general-purpose circuits that demand a durable, high-capacitance radial-lead capacitor with a wide operating temperature range.

Unique Advantages

• Measurable low-impedance performance — 38 mΩ impedance supports lower voltage ripple and improved transient response in power systems.
• High ripple-current capability — Rated ripple currents of 3.376 A (120 Hz) and 4.22 A (10 kHz) enable reliable operation under continuous AC superimposed on DC.
• Extended high-temperature life — 10,000-hour endurance at 105°C provides predictable long-term performance in thermally stressful environments.
• Compact radial-lead form factor — φ18 × 35.5 mm can with 7.5 mm lead spacing offers a balance of capacitance density and through-hole mounting simplicity.
• Clear electrical limits — Specified tanδ (0.16 at 20°C, 120 Hz) and defined leakage current (1155 µA) enable precise design margining and thermal budgeting.
• Packaging flexibility — Available in bulk (no terminal forming) or bag packing to match assembly and handling preferences.
