UHE1H331MPD

The UHE1H331MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UHE series, offering a 330 µF capacitance at a 50 V rating in a compact φ10 × 25 mm can. It combines low impedance, measurable dissipation factor, and long-term endurance for general-purpose electronic designs.

Designed for applications that require polarized electrolytic capacitance with reliable ripple handling and extended life at elevated temperature, this part suits a range of general-purpose circuits where compact size and stable performance over time matter.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 50 V rated voltage and a capacitance tolerance of −20% to +20%.
• Low Impedance — Rated impedance of 220 mΩ, supporting lower AC voltage drop in filtering and decoupling applications.
• Ripple Current Performance — Low-frequency ripple current of 1.008 A (120 Hz) and high-frequency ripple current of 1.44 A (10 kHz), specified for the part.
• Long Life / Endurance — Endurance specified as 7000 hours at 105°C under rated voltage conditions, reflecting extended operational life in elevated-temperature environments.
• Temperature Range — Operational temperature range from −40°C to +105°C to support a wide ambient range.
• Electrical Leakage & Dissipation — Leakage current specified at 165 µA and tangent of loss angle (tan δ) of 0.1 measured at 20°C, 120 Hz.
• Package & Mounting — Radial lead can package (φ10 × 25 mm), lead spacing 5 mm (±0.5 mm), supplied in bulk or bag packing without terminal forming.
• RoHS Compliant — Compliant with RoHS directive as indicated in series documentation.

Typical Applications

• General Purpose Electronics — Provides 330 µF / 50 V polarized capacitance for general-purpose circuit needs where compact radial electrolytics are required.
• Power Filtering and Decoupling — Suited for smoothing and decoupling tasks where specified ripple currents (1.008 A at 120 Hz, 1.44 A at 10 kHz) and low impedance are important.
• Industrial and Control Circuits — Useful in control and industrial boards that operate across −40°C to +105°C and require long endurance at elevated temperature.
• Compact Board Layouts — The φ10 × 25 mm can and 5 mm lead spacing make it appropriate for space-conscious, through-hole assemblies using radial components.

Unique Advantages

• Measured Low Impedance: 220 mΩ impedance reduces AC voltage loss and supports stable filtering performance.
• Defined Ripple Capability: Specified ripple current values at both low and high frequencies allow designers to match the capacitor to expected AC stress levels.
• Extended Endurance at 105°C: 7000 hours rated life at 105°C provides quantifiable reliability for long-term deployments in warm environments.
• Compact Radial Can: φ10 × 25 mm package with 5 mm lead spacing offers a small footprint for through-hole designs while preserving adequate capacitance.
• Controlled Leakage and Loss: Leakage current of 165 µA and tan δ of 0.1 (20°C, 120 Hz) give clear electrical performance metrics for design validation.
• RoHS Compliance: Meets RoHS requirements as documented for the UHE series, supporting regulatory-driven procurement.
