UHW1J821MHD6

The UHW1J821MHD6 is a radial lead aluminum electrolytic capacitor engineered for general-purpose power applications that require high ripple-handling and reliable long-term operation. It combines a compact can-style package with a high capacitance of 820 µF and a 63 V rated voltage to support DC filtering and energy-smoothing duties in through-hole assemblies.

Designed as part of Nichicon’s UHW series, this capacitor offers low impedance, defined loss characteristics, and high-temperature endurance for designs operating across a broad temperature range of −40°C to 105°C.

Key Features

• Capacitance and Voltage — 820 µF nominal capacitance with a rated voltage of 63 V and ±20% tolerance, suitable for mid-voltage power circuits.
• Low Impedance, High Ripple Capability — Specified impedance of 140 mΩ and ripple currents of 1.476 A at 120 Hz and 2.46 A at 10 kHz support effective smoothing under AC ripple conditions.
• Low Loss and Leakage — Tangent of loss angle (tan δ) of 0.09 (63 V, 120 Hz) and specified leakage current of 516.6 µA for predictable dissipation and standby behavior.
• Long High‑Temperature Lifetime — Rated endurance of 12,000 hours at 105°C, providing extended service life in elevated-temperature environments.
• Radial Through‑Hole Package — Can-style radial package with φ18×20 L dimensions and 7.5 mm lead spacing for conventional through-hole assembly; supplied bulk/no terminal forming for mass production.
• Wide Operating Temperature — Usable across −40°C to 105°C to accommodate a range of ambient and operating conditions.

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling in power supplies where 820 µF at 63 V and defined ripple handling are required.
• High-ripple DC link and smoothing — Use in circuits that demand continuous ripple current handling up to the specified 120 Hz and 10 kHz values.
• Through-hole assembly designs — Radial lead form and 7.5 mm lead spacing make this capacitor suitable for conventional PCB layouts and manual or wave-solder production flows.

Unique Advantages

• High ripple tolerance: Ripple current ratings at 120 Hz and 10 kHz (1.476 A and 2.46 A, respectively) enable reliable performance in applications with significant AC components.
• Low impedance: 140 mΩ impedance improves filtering effectiveness and reduces voltage ripple under load.
• Controlled loss characteristic: tan δ of 0.09 at 63 V offers predictable dissipation for thermal and stability calculations.
• Extended high‑temperature endurance: 12,000 hours at 105°C gives designers a measurable long-term reliability metric for elevated-temperature deployments.
• Through‑hole convenience: Radial can package with 7.5 mm lead spacing and bulk/no terminal forming supports common assembly processes and production throughput.
• Robust leakage specification: Specified leakage current of 516.6 µA supports predictable standby and bias behavior in power systems.
