UHE2A181MHD6

The UHE2A181MHD6 is a radial-lead aluminum electrolytic capacitor from Nichicon's UHE series, providing a compact, low-impedance solution for general-purpose power applications. With a 180 µF capacitance at 100 V and a miniature φ18 × 15 mm can, it is designed for through-hole assemblies where high-voltage smoothing, decoupling and energy buffering are required.

Key value comes from its combination of low loss (tanδ 0.08 at 100 V), robust ripple handling (721 mA @120 Hz, 1.03 A @10 kHz) and long high-temperature endurance (10,000 hours at 105°C), offering reliable performance in demanding environments between −40°C and +105°C.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance rated at 100 V with ±20% tolerance for general-purpose DC energy storage and filtering.
• Low Loss & Low Impedance — Specified tanδ of 0.08 (at 100 V, 120 Hz, 20°C) and impedance listed as 500 mΩ, minimizing dissipation and improving ripple performance.
• Ripple Current Capability — Rated ripple current of 721 mA at 120 Hz and 1.03 A at 10 kHz, with frequency coefficients per the UHE series for higher-frequency operation.
• High-Temperature Endurance — 10,000-hour lifetime at 105°C under rated bias and ripple conditions, reflecting high reliability for long-life applications.
• Wide Operating Temperature Range — Operates from −40°C to +105°C for use across a broad set of environmental conditions.
• Compact Radial Package — φ18 × 15 mm can with 7.5 mm lead spacing and radial lead mounting simplifies through-hole PCB integration; available in bulk (no terminal forming) bag packing.
• RoHS Compliant — Meets RoHS requirements for restricted substances.

Typical Applications

• Power supply filtering — Bulk energy storage and smoothing on higher-voltage DC rails up to 100 V where long life at elevated temperature is required.
• DC/DC converters and regulators — Output decoupling and ripple reduction, leveraging the capacitor's low impedance and rated ripple currents at both low and high frequencies.
• Industrial control and instrumentation — Reliable DC energy buffering in control electronics operating across −40°C to +105°C and subject to continuous ripple stress.

Unique Advantages

• High voltage capability: 100 V rating enables use on higher-voltage rails without changing capacitor family.
• Long high-temperature lifetime: 10,000 hours at 105°C provides predictable endurance for designs targeting extended service life.
• Low loss and low impedance: tanδ 0.08 and 500 mΩ impedance reduce heat generation and improve efficiency under ripple load.
• Frequency-capable ripple handling: Rated ripple currents specified at 120 Hz and 10 kHz support both power-line and higher-frequency converter applications.
• Compact, through-hole form factor: φ18 × 15 mm can and 7.5 mm lead spacing suit space-constrained PCB layouts that require radial-lead components.
• RoHS compliant: Conforms to RoHS requirements for environmentally restricted substance control.
