UHE1C331MPD

The UHE1C331MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UHE series. It is a radial-lead, polarized capacitor specified at 330 µF and 16 V, designed for general-purpose electronic use.

Engineered for low impedance and extended life, this component provides long-term performance across a wide temperature range (‑40°C to 105°C) with endurance rated at 7000 hours at 105°C. Its compact φ8 × 11.5 mm can size and standard 3.5 mm lead spacing make it suitable for space-conscious through-hole designs.

Key Features

• Capacitance & Voltage – 330 µF nominal capacitance at a rated voltage of 16 V, with capacitance tolerance of -20% to +20%.
• Low Loss Factor – tanδ (DF) of 0.16 measured at 20°C, 120 Hz, for stable performance in AC ripple environments.
• Low Impedance – Rated impedance approximately 520 mΩ to support lower ripple and improved transient handling on power rails.
• Ripple Current Capability – Low-frequency ripple current of 448 mA (120 Hz) and high-frequency ripple current of 640 mA (10 kHz) for effective smoothing across frequency ranges.
• Leakage Current – Specified leakage current of 52.8 µA after standard initial conditions.
• Long Life & Temperature Range – Endurance of 7000 hours at 105°C with operating temperature range from -40°C to 105°C.
• Package & Mounting – Radial lead, polarized aluminum can (φ8 × 11.5 mm) with 3.5 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• Compliance & Availability – RoHS compliant and in mass production.

Typical Applications

• General-purpose DC power filtering – Use where a compact 330 µF, 16 V capacitor is needed to smooth and stabilize low-voltage power rails.
• Decoupling and bulk energy storage – Provides local energy buffering and decoupling for small power supplies and control electronics operating within the specified temperature range.
• Embedded and industrial electronics – Suited for through-hole designs that require long endurance (7000 h at 105°C) and reliable ripple handling over a wide temperature span.

Unique Advantages

• Compact footprint: φ8 × 11.5 mm can size provides high capacitance in a small radial-lead package for space-constrained boards.
• Designed for sustained high-temperature operation: Rated for 7000 hours at 105°C, offering predictable life performance in elevated-temperature environments.
• Broad ripple performance: Specified ripple currents at both low (120 Hz) and high (10 kHz) frequencies allow reliable smoothing across a range of switching and AC conditions.
• Low impedance and controlled dissipation: 520 mΩ impedance and tanδ of 0.16 (20°C, 120 Hz) support efficient power conditioning and reduced loss.
• Through-hole convenience: Radial lead form with 3.5 mm spacing simplifies manual assembly and prototype work while offering standard mounting compatibility.
• Regulatory readiness: RoHS compliance supports environmentally conscious designs and regulatory requirements.
