UKL1E100MDD

The UKL1E100MDD is a miniature aluminum electrolytic capacitor in Nichicon’s UKL low-leakage series, provided in a radial-lead can (φ5 × 11 mm) with 2 mm lead spacing. It delivers 10 µF capacitance at 25 V with low leakage and frequency-capable ripple performance targeted at compact electronic designs.

Engineered for audio and other space-constrained applications, this component combines a small footprint, low leakage current and defined endurance (2000 hours at 85°C) to support stable performance in through-hole assemblies.

Key Features

• Capacitance & Voltage — 10 µF rated capacitance at 25 V provides predictable energy storage for small-signal and power-rail support in compact boards.
• Low Leakage — Specified leakage current of 0.5 µA helps minimize DC loss and maintain bias integrity in sensitive circuits.
• Loss Angle (tan δ) — tanδ = 0.08 measured at 20°C, 120 Hz, suitable where controlled dissipation factor is required.
• Ripple Current Capability — Rated low-frequency ripple current of 70 mA (120 Hz) and high-frequency ripple current of 140 mA (10 kHz) for filtering across a range of frequencies.
• Temperature & Endurance — Operating range –40°C to +85°C with 2000 hours endurance at 85°C for predictable life characteristics under elevated temperature stress.
• Form Factor & Mounting — Radial lead package, size φ5 × 11 mm, 2 mm lead spacing (tolerance 0.5 mm) for straightforward through-hole assembly and compact layouts.
• Packaging & Compliance — Available in bulk or bag packing; RoHS compliant.

Typical Applications

• Audio circuitry — Designed for audio applications where low leakage and compact electrolytic capacitance support signal integrity and bias stability.
• Compact through‑hole boards — Small φ5 × 11 mm can and 2 mm lead spacing fit tight PCB real estate while retaining through-hole assembly compatibility.
• General-purpose electronic assemblies — Provides a compact, low-leakage option for designs requiring 10 µF / 25 V electrolytic capacitance with defined ripple handling and endurance.

Unique Advantages

• Compact footprint: φ5 × 11 mm size and 2 mm lead spacing enable space-efficient placement on densely populated PCBs.
• Low leakage performance: 0.5 µA leakage current reduces DC bleed and helps preserve circuit bias over time.
• Frequency-capable ripple handling: 140 mA rating at 10 kHz supports high-frequency filtering needs beyond mains-frequency ripple.
• Defined endurance: 2000 hours at 85°C gives clear expectations for life performance in thermally stressed environments.
• Radial-lead convenience: Through-hole radial configuration simplifies assembly for hand-built and wave-solder applications.
• RoHS compliant: Manufactured to meet RoHS requirements for regulated markets.
