UHE2A331MHD

The UHE2A331MHD is a Nichicon UHE-series aluminum electrolytic capacitor in a radial-lead can, rated for 330 µF at 100 V. It combines a compact φ12.5 × 40 mm can with low impedance and long endurance to serve general-purpose electronic designs.

Designed for applications that require polarized bulk capacitance with reliable performance across –40°C to 105°C, this part delivers specified ripple current handling and leakage characteristics for sustained operation up to 10,000 hours at 105°C.

Key Features

• Capacitance & Voltage: 330 µF capacitance rated at 100 V for high-voltage polarized applications.
• Low Impedance: Specified impedance of 300 mΩ to support efficient AC ripple handling and minimize voltage drop under load.
• Ripple Current Capability: 896 mA at 120 Hz (low frequency) and 1.28 A at 10 kHz (high frequency) for effective smoothing under varying ripple conditions.
• Leakage Current: Leakage current specified at 330 µA, meeting typical electrolytic polarization requirements.
• Long Endurance: Rated life of 10,000 hours at 105°C (for 16–100 V range) as part of the UHE series endurance specifications.
• Temperature Range: Operates from –40°C to 105°C to accommodate a wide range of ambient conditions.
• Radial Lead Package: φ12.5 × 40 mm can with 5.0 mm lead spacing (±0.5 mm), radial-lead mounting for through-hole designs.
• Packaging: Available in bulk (no terminal forming) and bag packing for flexible procurement and assembly handling.
• RoHS Compliant: Meets RoHS requirements as declared for the UHE series.

Typical Applications

• General-purpose electronic circuits: Polarized radial-lead bulk capacitance for a wide range of circuit designs classified as general purpose.
• High-temperature or continuous-duty systems: Suited to designs requiring up to 10,000 hours of endurance at 105°C.
• Circuits requiring significant ripple handling: Use where specified low- and high-frequency ripple currents (896 mA @120 Hz, 1.28 A @10 kHz) are needed.

Unique Advantages

• High-voltage capability: 100 V rating enables use in higher-voltage polarized applications while retaining compact can size.
• Long-term reliability: 10,000-hour endurance at 105°C provides predictable aging characteristics for prolonged deployments.
• Strong ripple performance: Distinct low- and high-frequency ripple current specifications offer designers measurable acceptance criteria for filtering tasks.
• Compact radial form factor: φ12.5 × 40 mm can with 5 mm lead spacing supports space-conscious through-hole layouts.
• Measured electrical characteristics: Defined impedance (300 mΩ) and leakage current (330 µA) simplify selection and verification in design validation.
• RoHS compliance: Conforms to RoHS requirements for environmentally restricted substance compliance.
