UHE1H122MHD

The UHE1H122MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UHE series, offering 1.2 mF capacitance at a 50 V rating in a compact φ16 × 30.5 mm can. Designed for general-purpose electronic circuits, it provides a balance of high capacitance, low impedance, and extended endurance for reliable bulk energy storage and ripple handling.

Key Features

• Capacitance & Voltage  1.2 mF (1200 µF) rated at 50 V with a tolerance of −20% to +20%.
• Low Impedance  Rated impedance of 66 mΩ helps reduce voltage drop under ripple conditions.
• Ripple Current Capability  Low-frequency ripple current 2.408 A (120 Hz) and high-frequency ripple current 3.01 A (10 kHz) for handling AC ripple across a wide frequency range.
• Loss and Leakage  Tangent of loss angle (tanδ) 0.1 (measured at 20°C, 120 Hz) and leakage current specified at 600 µA.
• High Endurance  Rated for 10,000 hours at 105°C, offering long life under elevated operating temperatures.
• Operating Range  Wide operating temperature range from −40°C to +105°C.
• Mechanical & Mounting  Radial lead package with φ16 × 30.5 mm dimensions and 7.5 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing.
• Compliance & Production  RoHS compliant and currently in mass production under Nichicon's UHE series.

Typical Applications

• General-purpose electronic circuits  Suited where a 1.2 mF, 50 V radial aluminum electrolytic capacitor is required for bulk capacitance in general-purpose designs.
• Higher-temperature environments  Applicable in designs that require continuous operation up to 105°C and long endurance (10,000 hours at 105°C).
• Assemblies with radial-lead mounting  Fits through-hole radial mounting workflows with standard 7.5 mm lead spacing and can-style packaging.
• Production-friendly packaging  Available in bulk (no terminal forming) or bag packing to accommodate different board assembly and inventory workflows.

Unique Advantages

• High-capacitance in a compact can  1200 µF in a φ16 × 30.5 mm package delivers substantial bulk capacitance while conserving board area.
• Low impedance for improved ripple performance  66 mΩ impedance combined with rated ripple currents (2.408 A @120 Hz, 3.01 A @10 kHz) reduces voltage excursions under AC stress.
• Specified high-temperature longevity  10,000-hour endurance at 105°C supports long-term operation in elevated-temperature applications.
• Controlled electrical losses and leakage  tanδ of 0.1 (20°C, 120 Hz) and leakage current of 600 µA provide predictable behavior for circuit designers.
• RoHS compliance and production readiness  Environmentally compliant and available in mass production for stable supply to manufacturing programs.
• Flexible packaging options  Bulk and bag packing choices simplify handling for different assembly and stocking processes.
