UHW1J821MHD

The UHW1J821MHD is a radial-lead aluminum electrolytic capacitor offering 820 µF capacitance at a 63 V rating in a compact φ12.5×35.5 mm can. It is part of Nichicon’s UHW series, designed for miniature size with high ripple current and high reliability in general-purpose electronic equipment.

Key electrical characteristics include low impedance (110 mΩ), measured dissipation factor (tanδ) of 0.09 at 20°C/120 Hz, and specified ripple current handling at both low and high frequencies. The part is RoHS compliant and available in mass-production quantities with bulk/bag packaging.

Key Features

• Capacitance & Tolerance: 820 µF nominal with ±20% tolerance at 20°C/120 Hz for stable bulk capacitance in a small footprint.
• Rated Voltage: 63 V DC rating suitable for mid-voltage general-purpose designs.
• High Ripple Current Capability: Rated for 1.824 A at 120 Hz and 3.04 A at 10 kHz to support AC ripple conditions across low and high frequencies.
• Low Impedance: 110 mΩ impedance for improved performance at higher frequencies and reduced voltage drop under ripple load.
• Thermal and Life Reliability: Operating temperature range −40°C to +105°C with endurance specified at 12,000 hours at 105°C.
• Electrical Loss and Leakage: tanδ (DF) 0.09 measured at 20°C/120 Hz; leakage current specified as 516.6 µA.
• Package & Mounting: Radial lead can, size φ12.5×35.5 mm (L: 3.55 × D: 1.25 cm) with 5.0 mm lead spacing (±0.5 mm); available bulk/no terminal forming or bag packing.
• Compliance & Availability: RoHS compliant and listed as mass production status for program-level availability.

Typical Applications

• General-purpose electronic equipment — Provides compact bulk capacitance where miniature size and high ripple current handling are required.
• Power modules and supplies — Used where a 63 V rated electrolytic with specified ripple capability and low impedance is needed.
• Industrial control equipment — Suitable for designs operating across −40°C to +105°C with long endurance at elevated temperature.

Unique Advantages

• Compact high-capacitance form factor: 820 µF in a φ12.5×35.5 mm can saves PCB space while maintaining bulk energy storage.
• Measured low dissipation: tanδ of 0.09 at 20°C/120 Hz supports predictable loss behavior in AC applications.
• Wide frequency ripple support: Defined ripple currents at both 120 Hz and 10 kHz (1.824 A and 3.04 A) accommodate a range of ripple environments.
• Long endurance at high temperature: 12,000 hours rated life at 105°C provides a quantified reliability baseline for thermal-stressed designs.
• Engineered for stability: Low impedance (110 mΩ) and RoHS compliance contribute to reliable operation and regulatory alignment.
• Production readiness: Mass production status and standard radial-lead packaging simplify procurement and assembly planning.
