UHE2A820MPD

The UHE2A820MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UHE series, designed for general-purpose power applications that require compact size and extended high-temperature endurance. It combines a 100 V rated voltage with 82 µF capacitance in a φ10 × 20 mm can, offering a balance of energy storage, ripple handling and long life for industrial and electronic power designs.

Engineered for reliability, this part delivers low impedance, controlled loss (tan δ), and specified ripple-current capability across low and high frequencies, making it suitable for DC power rails, control electronics and other boards where a rugged radial electrolytic is required.

Key Features

• Capacitance & Voltage — 82 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance, providing stable bulk energy storage for 100 V class circuits.
• Low Impedance & Loss — Measured impedance of 940 mΩ and tan δ of 0.08 (20°C, 120 Hz), supporting efficient filtering and decoupling with reduced loss.
• Ripple Current Capability — Rated ripple current of 362.6 mA at 120 Hz and 518 mA at 10 kHz, enabling effective smoothing of both low- and high-frequency ripple components.
• Long Life at Elevated Temperature — Endurance specified for 7000 hours at 105°C (for rated voltages 16–100 V, φD = 8,10), supporting higher-temperature continuous operation.
• Robust Operating Range — Operates from −40°C to +105°C, allowing deployment across a wide range of environmental conditions.
• Compact Radial Package — φ10 × 20 mm can with 5 mm lead spacing (±0.5 mm) and radial-lead mounting for through-hole designs where board-level serviceability and mechanical ruggedness are desired.
• Leakage Current — Specified leakage current of 82 µA, consistent with reliable long-term bias behavior after application of rated voltage.
• RoHS Compliant & Production Ready — RoHS status compliant and listed as mass production with bulk/bag packaging options for volume assembly and prototyping.

Typical Applications

• Power Supplies — Bulk filtering and smoothing on 100 V rails where compact, high-voltage capacitance is required to stabilize DC outputs.
• Industrial Control Electronics — Energy storage and decoupling in motor controllers, drives and PLC power subsystems operating in elevated ambient temperatures.
• Instrumentation & Measurement — Supply decoupling and transient energy support in test equipment and measurement systems needing low-loss, stable capacitance.
• Embedded Power Modules — Local energy reservoir and ripple suppression on power boards and converters using through-hole radial components.

Unique Advantages

• High-Voltage Capability: 100 V rating provides margin for designs requiring elevated DC bus voltages without increasing footprint dramatically.
• Compact Footprint: φ10 × 20 mm can and 5 mm lead spacing deliver a small, serviceable through-hole solution for tight board layouts.
• Low Loss & Impedance: tan δ = 0.08 and 940 mΩ impedance help reduce heat generation and improve filtering efficiency under ripple loading.
• Extended High-Temperature Endurance: 7000 hours at 105°C supports long-term reliability in thermally demanding applications.
• Frequency-Responsive Ripple Handling: Specified ripple currents at both 120 Hz and 10 kHz indicate suitability for mixed-frequency ripple environments.
• Production-Ready Packaging: Available in bulk or bag packing and listed as mass production for streamlined procurement and assembly.
