UKL1E151MPD

The UKL1E151MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKL series, optimized for low leakage performance. It provides 150 µF capacitance at a 25 V rating in a compact φ10 × 12.5 mm can, targeting audio and related electronic equipment that require reliable polarized bulk capacitance with controlled leakage and ripple handling.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with ±20% tolerance at a 25 V rated voltage, suitable where defined bulk capacitance is required.
• Low Leakage — Specified leakage current of 7.5 µA, supporting designs that need minimized DC leakage.
• Ripple Current Performance — Rated ripple currents of 370 mA at 120 Hz (low frequency) and 555 mA at 10 kHz (high frequency), enabling reliable AC ripple handling across common frequency ranges.
• Endurance & Temperature Range — 2000 hours endurance at 85°C and operating temperature range of −40°C to +85°C, providing predictable lifetime behavior under rated conditions.
• Radial Lead Package — φ10 × 12.5 mm aluminum can with 5 mm lead spacing (±0.5 mm), supplied in bulk (no terminal forming) or bag packing for through-hole assembly.
• RoHS Compliant — Conforms to RoHS requirements for restricted substances.

Typical Applications

• Audio equipment — Used in audio electronics where low-leakage polarized capacitance is required for power supply smoothing and general circuit capacitance.
• Embedded electronics — Suitable for general-purpose through-hole designs that require reliable bulk capacitance within the stated temperature and endurance limits.
• Power filtering — Applied where specified ripple current ratings at 120 Hz and higher frequencies are required for filtering tasks.

Unique Advantages

• Measured low leakage: The specified 7.5 µA leakage current helps maintain circuit bias stability and reduces unwanted DC loss in sensitive circuits.
• Frequency-aware ripple handling: Separate ripple current ratings at 120 Hz (370 mA) and 10 kHz (555 mA) allow designers to evaluate performance across both low and high frequency ripple environments.
• Compact radial can: φ10 × 12.5 mm package with standard 5 mm lead spacing simplifies placement in tight through-hole layouts while retaining usable capacitance.
• Documented endurance: Rated for 2000 hours at 85°C, enabling predictable life-expectancy planning under rated stress conditions.
• Supply flexibility: Available in bulk (no terminal forming) or bag packing to match assembly and inventory handling preferences.
• Regulatory compliance: RoHS compliance supports use in designs targeting restricted-substance requirements.
