UKL2A150MPD

The UKL2A150MPD is a miniature aluminum electrolytic capacitor from Nichicon's UKL series. It is a radial lead, polarized capacitor specified at 15 µF and 100 V, designed for compact board-level use where low leakage and controlled dissipation factor are important.

Key characteristics include low leakage current, a measured tanδ of 0.07 (20 °C, 120 Hz), ripple current capability across low and high frequencies, and a rated endurance of 2000 hours at 85 °C. The part is supplied in bulk/bag packing and is RoHS compliant. Status: End Of Life — this part is scheduled for discontinuation and is not recommended for new designs.

Key Features

• Electrical Performance — Rated capacitance 15 µF with tolerance ±20% and rated voltage 100 V; polarized for DC decoupling and smoothing.
• Low Leakage — Specified leakage current of 3 µA (measured at 20 °C), supporting applications that require minimal DC loss over time.
• Controlled Dissipation — tanδ = 0.07 at 20 °C, 120 Hz, providing predictable AC loss characteristics for audio and signal circuits.
• Ripple Current Capability — Low-frequency ripple current 110 mA at 120 Hz and high-frequency ripple current 220 mA at 10 kHz, enabling reliable operation under AC ripple stress.
• Reliability & Lifetime — Endurance rated at 2000 hours at 85 °C; operating temperature range −40 °C to +85 °C.
• Compact Radial Package — Can-style radial package (φ8 × 11.5 mm) with 3.5 mm lead spacing and bulk/bag packing (no terminal forming).
• Regulatory Compliance — RoHS compliant.

Typical Applications

• Audio systems — Suitable for audio electronics where low leakage and controlled loss (tanδ) help maintain signal integrity and power supply stability.
• Power supply smoothing — Compact radial form factor and rated ripple currents make it applicable for local decoupling and smoothing in compact power rails.
• Repair and maintenance — With its miniature can package and standard radial lead spacing, the UKL2A150MPD is appropriate for component replacement in existing assemblies.

Unique Advantages

• Low steady-state leakage: 3 µA leakage current at 20 °C reduces DC losses and drift in sensitive circuits.
• Predictable AC behavior: tanδ of 0.07 (20 °C, 120 Hz) provides known dissipation characteristics for audio and timing applications.
• Dual-frequency ripple handling: Rated ripple currents of 110 mA (120 Hz) and 220 mA (10 kHz) cover both mains-frequency and higher-frequency switching environments.
• Compact radial footprint: φ8 × 11.5 mm can with 3.5 mm lead spacing fits tight board layouts while retaining through-hole reliability.
• Operational range and endurance: −40 °C to +85 °C operation and 2000 hours endurance at 85 °C support sustained performance in typical electronics environments.
• RoHS compliant: Meets RoHS directive requirements for lead-free assembly processes.

Why Choose UKL2A150MPD?

The UKL2A150MPD offers a compact, low-leakage solution for circuits that require a 15 µF, 100 V polarized capacitor with defined dissipation and ripple-current behavior. Its combination of low tanδ, controlled leakage, and rated ripple currents makes it well suited to audio and board-level power conditioning tasks where space is limited and predictable electrical performance matters.

Note that this part is listed as End Of Life and is intended for repair, legacy production support, or short-term inventory needs rather than new designs. Use this part when a direct-match replacement or equivalent performance in existing assemblies is required.
