UKL2A101MHD

The UKL2A101MHD is a radial-lead aluminum electrolytic capacitor offering 100 µF capacitance at a 100 V rated voltage. It belongs to Nichicon’s UKL series, a standard low-leakage-current family designed for applications where stable DC performance and controlled dissipation are important.

Typical use is in audio equipment where a combination of high-voltage handling, moderate ripple capability, and long endurance are required. Key value propositions include low leakage, defined high- and low-frequency ripple ratings, and a compact radial-can package.

Key Features

• Electrical Performance — 100 µF capacitance with ±20% tolerance and polarized construction; rated for 100 V operation.
• Low Leakage — Specified leakage current of 20 µA, supporting stable DC bias behavior in long-running systems.
• Loss Factor (tan δ) — tanδ = 0.08 measured at 20°C, 120 Hz, indicating controlled dissipation for audio-frequency use.
• Ripple Current Capability — Rated low-frequency ripple current of 370 mA at 120 Hz and high-frequency ripple current of 555 mA at 10 kHz for handling both mains-related and higher-frequency disturbances.
• Reliability & Endurance — 2000 hours endurance at 85°C under rated voltage, providing predictable aging characteristics for lifecycle planning.
• Mechanical & Packaging — Radial lead can, case size φ12.5 × 20 mm, lead spacing 5 mm (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Operating Range — Rated for −40°C to +85°C operation to accommodate a broad range of environmental conditions.
• Regulatory — RoHS compliant.

Typical Applications

• Audio — Designed for use in audio equipment where low leakage and reliable ripple performance support signal integrity and power filtering.

Unique Advantages

• Low steady-state leakage: The specified 20 µA leakage supports stable biasing and reduces DC loss in long-duration applications.
• High-voltage capability: 100 V rating enables use in higher-voltage audio power supplies and circuits that require greater headroom.
• Frequency-aware ripple handling: Separate ripple ratings for 120 Hz (370 mA) and 10 kHz (555 mA) make it easier to size capacitors for both low- and high-frequency disturbances.
• Predictable endurance: 2000 hours at 85°C under rated voltage provides defined lifecycle expectations for design validation and maintenance planning.
• Compact radial package: φ12.5 × 20 mm can and 5 mm lead spacing simplify layout in through-hole assemblies where radial components are preferred.
• RoHS compliance: Meets environmental requirements for lead-free manufacturing processes.

Why Choose UKL2A101MHD?

UKL2A101MHD is positioned for designs that require a balance of low leakage, high-voltage handling, and clear ripple-current specifications in a compact radial-can form factor. It is suitable for audio equipment designers and engineers who need predictable electrical behavior (tanδ, leakage, ripple) and defined endurance under elevated temperatures.

Choosing this part offers straightforward integration into through-hole assemblies, with packaging options that support assembly and inventory preferences. The combination of electrical, mechanical, and environmental specifications helps reduce uncertainty during component selection and system validation.
