UHE1J821MHD

The UHE1J821MHD is an aluminum electrolytic capacitor in a radial-lead can, offering 820 µF capacitance at a 63 V rating for general-purpose electronic designs. It is part of Nichicon's UHE series, which delivers miniature sizing with specifications targeted at long life and measurable low-impedance performance.

Key attributes include a wide operating temperature range from −40 °C to 105 °C, a rated lifetime of 10,000 hours at 105 °C, and RoHS compliance—making it suitable for designs that require stable capacitance, predictable leakage, and substantial ripple handling in a compact radial package.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 63 V rated voltage and tolerance of −20% to +20%.
• Compact Radial Package — Radial lead can with dimensions φ16 × 30.5 mm (L: 3.05 × D: 1.6 cm) and 7.5 mm lead spacing (±0.5 mm).
• Low Impedance — Specified impedance of 200 mΩ, supporting lower voltage drop under ripple and transient conditions.
• Loss Tangent (tan δ) — tan δ = 0.09 (measured at 20 °C, 120 Hz) for predictable dissipation characteristics.
• Ripple Current Capability — Low-frequency ripple current 1.2375 A at 120 Hz and high-frequency ripple current 1.65 A at 10 kHz, enabling reliable AC load handling across common regulator and converter frequencies.
• Leakage Current — Leakage current specified at 516.6 µA for predictable bias behavior.
• Long Life / Endurance — Rated for 10,000 hours at 105 °C under the specified endurance conditions.
• Environmental Compliance — RoHS compliant.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing for flexible procurement and assembly workflows.

Typical Applications

• General-purpose electronic assemblies — Provides 820 µF capacitance at 63 V for circuits that require bulk energy storage with long operational life.
• Power stage subcircuits — Supports ripple current up to 1.2375 A at 120 Hz and 1.65 A at 10 kHz, useful where AC ripple handling is required.
• Temperature-challenged installations — Rated for operation from −40 °C to 105 °C with a 10,000-hour endurance at 105 °C for designs needing extended high-temperature reliability.

Unique Advantages

• Measurable low-impedance performance: 200 mΩ impedance delivers reduced voltage drop under load, improving stability in power circuits.
• Designed for long-term reliability: 10,000-hour endurance at 105 °C supports extended service life in sustained high-temperature environments.
• Dual-frequency ripple capability: Specified ripple currents at both 120 Hz and 10 kHz help designers quantify performance across low- and high-frequency domains.
• Compact radial form factor: φ16 × 30.5 mm can and 7.5 mm lead spacing provide a space-efficient solution for through-hole mount designs.
• Predictable electrical characteristics: Specified tan δ (0.09 at 20 °C, 120 Hz) and defined leakage current (516.6 µA) enable reliable modeling and margining in designs.
• Procurement flexibility: Available in bulk or bag packing to match production and prototyping needs.
