UHE1A123MHD

The UHE1A123MHD is a Nichicon UHE series miniature aluminum electrolytic capacitor in a radial-lead can, designed for general-purpose electronic applications requiring high capacitance and long operational life. This high-reliability type offers 12,000 µF at 10 V with low impedance and extended endurance at elevated temperature.

Engineered for sustained performance, the device combines a compact φ18 × 40 mm can with radial leads (7.5 mm spacing) and is specified for operation from −40°C to 105°C and 8,000 hours endurance at 105°C.

Key Features

• High Capacitance: 12,000 µF (12 mF) nominal capacitance provides substantial energy storage in a compact footprint for smoothing and bulk decoupling.
• Rated Voltage: 10 V DC rating suitable for low-voltage power rails and circuits that require dependable 10 V operation.
• Low Impedance: Rated impedance of 32 mΩ supports stable performance under load and contributes to effective ripple attenuation.
• High Ripple Current Capability: Low-frequency ripple current 3.424 A at 120 Hz and high-frequency ripple current 4.28 A at 10 kHz for robust handling of AC components on DC rails.
• Long Life and Reliability: Endurance specified at 8,000 hours at 105°C (for 6.3–10 V, case sizes φD ≥ 12.5), supporting extended operation in elevated-temperature environments.
• Electrical Loss Characteristic: Tangent of loss angle (tan δ) of 0.41 measured at 20°C, 120 Hz for this capacitance value, indicating predictable dissipation characteristics.
• Leakage Current: Specified leakage current of 1,200 µA for predictable standby and quiescent behavior.
• Mechanical and Packaging: φ18 × 40 mm can with radial leads, 7.5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing for flexible handling.
• Operating Temperature Range: −40°C to 105°C to support a broad range of environmental conditions.
• RoHS Compliant: Meets RoHS requirements as noted in the product data.

Typical Applications

• General-purpose electronic circuits: Used where a 12,000 µF, 10 V polarized electrolytic capacitor is required for bulk energy storage and decoupling in board-level designs.
• Power rail smoothing: Deployed on low-voltage DC rails to reduce ripple and support transient currents, leveraging its specified low impedance and high ripple current ratings.
• Long-life high-temperature environments: Selected for designs that require 8,000 hours endurance at 105°C while maintaining capacitance and leakage specifications.

Unique Advantages

• High volumetric capacitance: 12,000 µF in a φ18 × 40 mm can minimizes board space for a given stored energy requirement.
• Strong ripple handling: Rated ripple currents at both low and high frequencies allow the capacitor to cope with AC components across common switching and power-supply frequencies.
• Predictable aging and endurance: Endurance specified at 8,000 hours at 105°C provides a clear specification for lifetime planning in thermal-stressed designs.
• Low impedance for stable performance: 32 mΩ impedance helps maintain voltage stability under dynamic load conditions.
• Flexible packaging options: Offered in bulk and bag packing to support prototyping and production handling preferences.
• Regulatory compliance: RoHS status confirmed for ease of integration into compliant assemblies.
