UHW1K122MHD

The UHW1K122MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can. It delivers 1200 µF capacitance at an 80 V rating with a compact φ16 × 40 mm case and 7.5 mm lead spacing.

Designed for general-purpose electronics, this part targets applications that require high ripple handling, stable performance across –40 °C to 105 °C, and long endurance under elevated temperature stress.

Key Features

• Capacitance & Voltage 1200 µF nominal capacitance with an 80 V rated voltage and a tolerance of −20% to +20%.
• Radial lead package φ16 × 40 mm can with 7.5 mm lead spacing (±0.5 mm) for through-hole mounting and conventional PCB assembly.
• High ripple current capability Low-frequency ripple current 2.106 A (120 Hz) and high-frequency ripple current 3.51 A (10 kHz), supporting demanding AC ripple conditions.
• Low impedance at frequency Impedance specified at 81 mΩ, and the series datasheet notes lower impedance in high-frequency ranges to support stable operation across frequencies.
• Loss and leakage characteristics Tangent of loss angle (tan δ) 0.09 (measured at 20 °C, 120 Hz) and leakage current 960 µA as specified for the part.
• Wide operating temperature & long life Rated for −40 °C to 105 °C with an endurance rating of 12,000 hours at 105 °C.
• Packaging Available in bulk (no terminal forming) and bag packing for flexible inventory and assembly handling.
• RoHS compliant Manufactured to meet RoHS requirements.

Typical Applications

• General-purpose power circuitry Suited for power rails and supply sections where an 80 V, 1200 µF capacitor with high ripple current capability is required.
• High-frequency ripple environments Appropriate where lower impedance at higher frequencies and specified high-frequency ripple current (3.51 A at 10 kHz) are important.
• High-temperature assemblies Applicable in designs that must operate across −40 °C to 105 °C and require extended lifetime (12,000 hours at 105 °C).

Unique Advantages

• High ripple handling: Rated ripple currents of 2.106 A (120 Hz) and 3.51 A (10 kHz) enable reliable performance under significant AC stress.
• Compact radial can: φ16 × 40 mm package with 7.5 mm lead spacing provides a balance of capacitance and board-space efficiency for through-hole designs.
• Frequency-capable performance: Lower impedance at high frequency (data from the series) and an 81 mΩ impedance figure support stable decoupling across frequency ranges.
• Long endurance at elevated temperature: 12,000-hour life rating at 105 °C gives predictable aging characteristics for long-term designs.
• Controlled electrical loss and leakage: tan δ = 0.09 (20 °C, 120 Hz) and specified leakage current provide measurable, verifiable electrical parameters for design validation.
• RoHS compliance and flexible packing: Environmentally compliant manufacture and bulk or bag packing options simplify procurement and assembly planning.
