UHW0J821MPD

The UHW0J821MPD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UHW series. It is a radial-lead, polarized capacitor specified at 820 µF and 6.3 V, designed for general-purpose power applications that require high ripple handling in a compact can.

Key attributes include high ripple current capability, a low-impedance profile at higher frequencies (as published for the UHW series), and extended endurance—8000 hours at 105°C—making it suitable for designs that demand sustained performance in elevated-temperature environments.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a rated voltage of 6.3 V and tolerance of −20% to +20% (±20%).
• Package & Mounting — Radial lead (can) package, size φ8 × 11.5 mm (φ8×11.5L) with lead spacing 3.5 mm (lead spacing tolerance ±0.5 mm); offered in bulk (no terminal forming) or bag packing.
• High Ripple Current — Rated low-frequency ripple current 720 mA at 120 Hz and high-frequency ripple current 1.2 A at 10 kHz, supported by the UHW series’ design for higher ripple handling.
• Low Impedance & Loss — Impedance specified at 360 mΩ and tangent of loss angle (tan δ) of 0.21 at 20°C, 120 Hz for the 6.3 V rating.
• Leakage & Reliability — Leakage current shown as 51.66 µA; endurance is 8000 hours at 105°C under DC bias plus rated ripple per the UHW series specification.
• Operating Range & Compliance — Operating temperature −40°C to +105°C and RoHS compliant; part status is mass production.

Typical Applications

• Power supply smoothing — Bulk capacitance and high ripple current capability make this part suitable for smoothing and decoupling in low-voltage power rails.
• DC–DC converter output filtering — Compact φ8 can and high-frequency ripple rating support use on converter outputs where space and ripple handling are constrained.
• General-purpose electronics — Designed for general-purpose use across electronics that require reliable electrolytic capacitance within −40°C to +105°C environment limits.

Unique Advantages

• Compact footprint with high ripple capacity: φ8×11.5 mm case offers a small package while supporting 720 mA (120 Hz) and 1.2 A (10 kHz) ripple currents, helping save PCB area without sacrificing ripple performance.
• Extended high-temperature endurance: Rated for 8000 hours at 105°C under the UHW series endurance conditions, providing predictable long-term behavior in elevated-temperature applications.
• Measurable low impedance: 360 mΩ impedance and specified tan δ allow engineers to quantify AC performance for filter and decoupling designs.
• Clear manufacturing and supply status: RoHS compliant and in mass production, with standard packing options (bulk or bag) for flexible procurement.
• Radial-lead form factor: Through-hole radial leads (3.5 mm spacing) simplify prototyping and retrofitting into existing through-hole designs.

Why Choose UHW0J821MPD?
