UKL1H100MDD

The UKL1H100MDD is a 10 µF, 50 V aluminum electrolytic capacitor from Nichicon’s UKL series, engineered for low leakage current in a compact radial‑lead package. It delivers a low dissipation factor and defined ripple current capability in a small φ5 × 11 mm can, making it suitable for compact audio and related electronic assemblies.

Status: End Of Life. This product is scheduled for discontinuation and is not recommended for new designs.

Key Features

• Electrical characteristics — 10 µF nominal capacitance with tolerance −20% to +20% at 120 Hz and 20°C; rated voltage 50 V.
• Low leakage current — Specified leakage current of 1 µA (measured after specified application time at 20°C), supporting applications where capacitor leakage must be minimized.
• Low dissipation factor — tanδ = 0.08 (measured at 20°C, 120 Hz), indicating low dielectric losses for the rated size and voltage.
• Ripple current capability — 70 mA at 120 Hz (low frequency) and 140 mA at 10 kHz (high frequency) for the 10 µF size, with frequency coefficients defined in the series datasheet.
• Endurance and temperature range — Rated for 2000 hours at 85°C; operating temperature range −40°C to +85°C.
• Compact radial package — Cylindrical can, dimension φ5 × 11 mm with radial leads and 2 mm lead spacing (±0.5 mm), supplied in bulk or bag packing (no terminal forming).
• Polarized, RoHS compliant — Polarized aluminum electrolytic construction and RoHS status compliant.

Typical Applications

• Audio systems — Suited for audio equipment applications where 10 µF capacitance, 50 V rating and low leakage are required for signal or supply circuits.
• Compact modules — Small φ5 × 11 mm can fits tightly packaged PCBs and compact audio modules that require radial lead mounting.
• Production and repair supply — Available in bulk or bag packing for production runs or field service replacement in existing equipment.

Unique Advantages

• Low-leakage performance — 1 µA leakage current supports circuits sensitive to leakage without requiring larger or more complex components.
• Low dielectric loss — tanδ of 0.08 reduces losses at audio frequencies and helps maintain signal integrity.
• Defined ripple handling — Specified ripple current at both low and high frequencies enables predictable thermal and performance planning in designs.
• Space-efficient form factor — φ5 × 11 mm radial can and 2 mm lead spacing enable use in compact PCB layouts and through‑hole assemblies.
• Clear lifecycle information — End Of Life status provided up front so procurement and design teams can plan for replacement or lifecycle management.
• Regulatory compliance — RoHS compliant construction for regulatory alignment in many markets.

Why Choose UKL1H100MDD?

UKL1H100MDD combines low leakage, low dissipation factor and a compact radial‑lead package to serve space‑constrained audio and related electronic equipment where minimizing leakage and dielectric loss is important. Its defined ripple current ratings and 2000‑hour endurance at 85°C provide quantifiable performance parameters for reliability planning.

This part is appropriate for teams maintaining or repairing existing designs that already specify the UKL series. Because the product is End Of Life and not recommended for new designs, use it where compatibility with legacy assemblies or stocked inventory is required and plan for alternative components for future designs.
