UHE0J822MHD

The UHE0J822MHD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UHE high‑reliability series. It delivers 8.2 mF of capacitance at a 6.3 V rating in a compact φ16 × 30.5 mm can, designed for general-purpose power-supply and energy-storage duties.

With low impedance, high ripple-current capability, and a long rated life at elevated temperature, this radial lead capacitor is targeted at designs that require bulk capacitance, robust thermal endurance, and reliable long-term operation.

Key Features

• High Capacitance: 8.2 mF (8200 µF) nominal capacitance for bulk energy storage and smoothing.
• Rated Voltage: 6.3 V rated working voltage for low-voltage power rails and hold-up circuits.
• Low Impedance: 50 mΩ impedance to support lower ripple voltage and improved transient response.
• High Ripple Current Capability: 2.76 A at 120 Hz and 3.45 A at 10 kHz to accommodate both low- and high-frequency ripple conditions.
• Endurance / Lifetime: Rated for 8000 hours at 105 °C, providing long-term stability under elevated temperature stress.
• Wide Operating Temperature: −40 °C to 105 °C suitable for a broad range of environmental conditions.
• Leakage and Dissipation: Leakage current specified at 516.6 µA and tanδ (DF) of 0.36 (measured at 20 °C, 120 Hz), enabling predictable dissipation and loss characteristics.
• Compact Radial Package: φ16 × 30.5 mm can, radial lead mounting with 7.5 mm lead spacing, available in bulk or bag packing for flexible assembly and inventory handling.
• Polarized Design: Polarized aluminum electrolytic construction intended for correct-polarity DC applications.
• RoHS Compliant & Production Ready: RoHS compliant and listed as mass production status for supply continuity.

Typical Applications

• Power-supply smoothing: Low impedance and high ripple-current capability make this capacitor suitable for bulk filtering on DC rails to reduce ripple and stabilize voltage.
• Hold-up and energy storage: High capacitance in a compact package provides local energy storage for short-term hold-up and transient support on low-voltage supplies.
• Industrial and control electronics: Long 8000‑hour life at 105 °C and −40 °C to 105 °C temperature range support continuous operation in industrial power modules and control equipment.
• Consumer and embedded power modules: Compact radial can and robust ripple performance address space-constrained designs that require reliable bulk capacitance.

Unique Advantages

• Large capacitance in a small footprint: 8200 µF in a φ16 × 30.5 mm case minimizes board area while delivering substantial bulk energy storage.
• Designed for ripple-heavy environments: Specified ripple currents of 2.76 A (120 Hz) and 3.45 A (10 kHz) let designers handle both low- and high-frequency ripple without overspecifying components.
• Predictable electrical losses: Measured tanδ of 0.36 and a defined leakage current (516.6 µA) provide clear parameters for thermal and power-loss budgeting.
• Long elevated-temperature life: 8000 hours at 105 °C for sustained reliability in demanding thermal conditions.
• Easy through-hole implementation: Radial lead format with 7.5 mm lead spacing simplifies assembly and replacement in serviceable designs.
• Production-ready compliance: RoHS compliance and mass-production status support procurement and volume assembly planning.
