UHE1H821MHD

The UHE1H821MHD is a miniature, high‑reliability aluminum electrolytic capacitor in a radial lead can configuration from Nichicon’s UHE series. It provides 820 μF capacitance at a 50 V rated voltage with low impedance characteristics and long operational life.

Designed for general‑purpose electronics, this component delivers measurable performance for designs that require sustained ripple handling, controlled dissipation factor, and operation across a wide temperature range.

Key Features

• Capacitance & Voltage — 820 μF rated capacitance with a 50 V rated voltage and a capacitance tolerance of −20% to +20%.
• Low Impedance — Specified impedance of 83 mΩ, supporting stable performance under load.
• Long Endurance — Rated for 10,000 hours at 105°C when used under the specified DC bias and ripple conditions.
• Ripple Current Capability — Low‑frequency ripple current of 1.883 A at 120 Hz and high‑frequency ripple current of 2.51 A at 10 kHz.
• Tangent of Loss Angle (tan δ) & Leakage — tan δ = 0.10 (measured at 20°C, 120 Hz) and leakage current of 410 μA.
• Package & Mounting — Radial lead can, size φ12.5 × 35.5 mm, lead spacing 5.0 mm (±0.5 mm), supplied in bulk or bag packing.
• Operating Range & Compliance — Operating temperature −40°C to +105°C; RoHS compliant and in mass production.

Typical Applications

• General‑Purpose Electronics — Suitable where a stable 820 μF, 50 V electrolytic capacitor is required for general‑purpose circuits.
• Power Supply Decoupling — Low impedance and quantified ripple current ratings support use in circuits requiring sustained ripple handling.
• Long‑Life Systems — Endurance rating of 10,000 hours at 105°C makes it appropriate for designs prioritizing long operational lifetime.
• Compact Radial Mount Designs — φ12.5 × 35.5 mm radial can with 5 mm lead spacing fits space‑constrained through‑hole layouts.

Unique Advantages

• Measured Low Impedance — 83 mΩ impedance provides predictable AC performance for smoothing and decoupling tasks.
• Documented Ripple Capability — Specified ripple current values at 120 Hz and 10 kHz clarify thermal and ripple handling for power designs.
• Proven Long Life — 10,000‑hour endurance at 105°C (for 16–100 V ratings on φD ≥ 12.5 cases) supports extended maintenance intervals.
• Compact Radial Can — Small footprint (φ12.5 × 35.5 mm) and 5 mm lead spacing enable straightforward through‑hole assembly and replacement in existing layouts.
• Controlled Dissipation — tan δ of 0.10 at 20°C/120 Hz and a defined leakage current help with predictable loss and standby current budgeting.
• Regulatory Compliance — RoHS compliance for materials and manufacturing.
