UHW2A820MPD

The UHW2A820MPD is a radial-lead, miniature aluminum electrolytic capacitor in Nichicon’s UHW series, rated 82 µF at 100 V. It combines a compact φ10 × 16 mm can and 5.0 mm lead spacing with design features targeted at high ripple-current applications.

Designed for general-purpose electronic equipment, the part delivers high-frequency performance and long endurance—including low impedance at high frequency, a wide operating temperature range of −40 °C to +105 °C, and a rated life of 12,000 hours at 105 °C.

Key Features

• Capacitance & Voltage: 82 µF nominal capacitance with a rated voltage of 100 V and capacitance tolerance of −20% to +20%.
• High ripple-current capability: Rated ripple current of 416 mA at 120 Hz and 1.04 A at 10 kHz, with a frequency coefficient that benefits high-frequency decoupling.
• Low impedance: Specified impedance of 470 mΩ, supporting effective smoothing and decoupling at higher frequencies.
• Endurance and reliability: Life rating of 12,000 hours at 105 °C under rated DC bias plus ripple current; leakage current specified at 82 µA.
• Thermal range and dissipation factor: Operating temperature −40 °C to +105 °C; tan δ (loss tangent) specified at 0.08 (20 °C, 120 Hz).
• Package and mounting: Radial lead (can) construction, polarization noted, physical size φ10 × 16 mm (D × L), lead spacing 5.0 mm (±0.5 mm), supplied in bulk or bag packing.
• RoHS compliant: Meets RoHS environmental requirements.

Typical Applications

• General-purpose power filtering: Bulk smoothing and output filtering in power supplies where a 100 V, 82 µF capacitor with high ripple capability is required.
• High-frequency decoupling: Decoupling and ripple suppression in circuits that operate or switch at higher frequencies, leveraging the capacitor’s low impedance and 10 kHz ripple rating.
• Industrial and electronic equipment: Energy storage and transient suppression in general-purpose electronic systems that require long endurance at elevated temperatures.

Unique Advantages

• High-frequency performance: Lower impedance at high frequencies and a 1.04 A ripple rating at 10 kHz enable effective decoupling in switching environments.
• Compact radial can: φ10 × 16 mm case with 5.0 mm lead spacing provides high capacitance and voltage in a small footprint for space-constrained designs.
• Long endurance at elevated temperature: 12,000-hour life at 105 °C supports sustained operation in demanding thermal conditions.
• Predictable leakage and dissipation: Specified leakage current (82 µA) and tan δ (0.08 at 20 °C, 120 Hz) allow straightforward thermal and loss budgeting in designs.
• Ready for assembly: Radial-lead package in bulk or bag packing simplifies through-hole assembly and handling.
• Regulatory compliance: RoHS compliance supports environmental and regulatory requirements for product builds.

Why Choose UHW2A820MPD?

The UHW2A820MPD positions itself as a compact, high-ripple-capacity solution for engineers needing reliable smoothing and decoupling at up to 100 V. Its combination of low impedance, high-frequency ripple capability, and long life at 105 °C makes it suitable for general-purpose electronic systems that demand sustained performance in a small radial can package.

This capacitor is well-suited to designers prioritizing predictable electrical behavior (leakage, tan δ, impedance) and robustness over long operating periods, while maintaining a compact footprint and simple through-hole mounting options.
