UHE2A271MHD

The UHE2A271MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for general-purpose electronic applications. With a rated capacitance of 270 µF at 100 V and a long endurance specification, it delivers reliable bulk capacitance in a compact package.

Engineered for extended life and low impedance, this Nichicon UHE series part supports designs that require sustained ripple handling, controlled loss angle, and operation across –40°C to 105°C.

Key Features

• Capacitance & Rated Voltage — 270 µF nominal capacitance at a rated voltage of 100 V, with a tolerance of -20% to +20% for predictable energy storage.
• Long Endurance — Rated for 10000 hours at 105°C under specified conditions, providing extended service life for demanding applications.
• Low Impedance & Loss — Low impedance (350 mΩ) and a tangent of loss angle (tan δ) of 0.08 measured at 20°C, 120 Hz and 100 V, supporting efficient AC performance.
• High Ripple Handling — Low-frequency ripple current of 798 mA at 120 Hz and high-frequency ripple current of 1.14 A at 10 kHz, enabling effective ripple filtering across frequency ranges.
• Leakage Current — Specified leakage current of 270 µA, measured per product conditions for predictable standby behavior.
• Robust Operating Range — Rated for operation from –40°C to 105°C to accommodate a wide set of environmental conditions.
• Radial Lead Package — Compact φ12.5 × 35.5 mm can with 5 mm lead spacing (±0.5 mm) for straightforward through-hole mounting and assembly; available in bulk or bag packing.
• RoHS Compliant — Conforms to RoHS requirements for environmental compliance.

Typical Applications

• General-Purpose Power Circuits — Bulk energy storage and smoothing where 270 µF at 100 V is required and long life is beneficial.
• Power Supply Filtering — AC ripple reduction and decoupling in supplies that demand low impedance and defined ripple-current capability.
• Industrial Electronics — Applications requiring extended endurance at elevated temperature and robust leakage and loss characteristics.

Unique Advantages

• Extended operational life: 10000-hour endurance at 105°C reduces service replacement frequency and supports longer product maintenance intervals.
• Measurable low-loss performance: tan δ of 0.08 (20°C, 120 Hz, 100 V) gives a clear, verifiable indicator of AC loss behavior for design validation.
• Frequency-flexible ripple handling: Specified ripple currents at 120 Hz and 10 kHz allow designers to account for both low- and high-frequency stress.
• Compact radial package: φ12.5 × 35.5 mm can with 5 mm lead spacing provides a small footprint for through-hole assemblies while retaining substantial capacitance.
• Predictable leakage: Leakage current specified at 270 µA enables accurate budgeting of standby and bias currents in system power plans.
• Regulatory compliance: RoHS status supports use in designs where restricted-substance compliance is required.
