UHW0J822MHD

The UHW0J822MHD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon's UHW series. It is a radial-lead, polarized capacitor specified at 8200 µF and 6.3 V, designed for general-purpose electronic applications that require compact size, high ripple-current capability and long endurance.

Key design attributes include low impedance at higher frequencies, elevated ripple current ratings, and a rated endurance of 10000 hours at 105°C—making it suitable for circuits where sustained performance and durability are required.

Key Features

• Capacitance and Voltage — 8.2 mF (8200 µF) nominal capacitance with a rated voltage of 6.3 V and a tolerance of −20% to +20%.
• High Ripple Current — Rated ripple current of 3.239 A at 120 Hz (low frequency) and 3.81 A at 10 kHz (high frequency), supporting circuits with significant AC ripple demands.
• Low Impedance — Impedance specified at 39 mΩ, benefiting high-frequency performance and reducing voltage drop under ripple conditions.
• Long Endurance — Life rating of 10000 hours at 105°C when used under the specified conditions, supporting long-term reliability.
• Wide Temperature Range — Operating temperature range from −40°C to +105°C for use across varied thermal environments.
• Physical and Mounting — Compact radial can package, size φ16 × 25L (D 16 mm × L 25 mm), lead spacing 7.5 mm, suitable for through-hole radial mounting layouts.
• Leakage and Loss — Leakage current 516.6 µA and dissipation factor (tan δ) 0.35 (measured at 20°C, 120 Hz), specified for predictable electrical behavior.
• Compliance & Packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing and is in mass production.

Typical Applications

• General Purpose Electronics — Provides bulk energy storage and smoothing in circuits designated as general purpose where a high-capacitance polarized capacitor is required.
• High-Ripple Current Circuits — Suited to power stages and supply rails that experience elevated AC ripple, leveraging the 3.239 A (120 Hz) and 3.81 A (10 kHz) ripple ratings.
• Space-Constrained Designs — Compact φ16 × 25 mm can and radial-lead form are useful where board space is limited but high capacitance is needed.

Unique Advantages

• High ripple-current capability: The specified ripple currents at both low and high frequencies enable use in demanding supply environments without increasing case size.
• Low impedance: 39 mΩ impedance helps maintain stable voltage under dynamic load and improves high-frequency performance.
• Extended endurance at elevated temperature: 10000 hours at 105°C provides predictable longevity for designs that operate hot or require long service life.
• Compact radial package: φ16 × 25L can and 7.5 mm lead spacing deliver high capacitance in a small through-hole footprint for easy layout integration.
• Measured electrical characteristics: Specified leakage current (516.6 µA) and tan δ (0.35 at 20°C, 120 Hz) support reliable electrical design and selection.
• RoHS compliant and production-ready: Environmentally compliant construction and mass-production availability simplify sourcing and regulatory considerations.
