UKL1H151KPD

The UKL1H151KPD is a miniature radial-lead aluminum electrolytic capacitor from Nichicon’s UKL series, offered as a standard-type, low-leakage device. It provides 150 µF capacitance at a 50 V rating in a compact φ10 × 20 mm can with 5 mm lead spacing, intended for applications where a polarized, low-loss capacitor is required.

Key electrical characteristics include a low leakage current (15 µA), low dissipation factor (tanδ = 0.1 at 20°C, 120 Hz), and rated ripple currents of 420 mA at 120 Hz and 630 mA at 10 kHz. Operating temperature range is −40°C to +85°C with an endurance rating of 2000 hours at 85°C. Status: End Of Life.

Key Features

• Capacitance and Voltage 150 µF nominal capacitance with a rated voltage of 50 V and ±10% tolerance, suitable for polarized circuit requirements.
• Low Leakage Current Specified leakage current of 15 µA, aligned with the UKL series’ low-leakage design for reduced standby loss.
• Low Dissipation Factor tanδ = 0.1 measured at 20°C, 120 Hz, indicating low loss for improved efficiency in AC or ripple conditions.
• Ripple Handling Rated ripple currents of 420 mA (120 Hz) and 630 mA (10 kHz) provide defined capability for smoothing and decoupling under low- and high-frequency ripple.
• Compact Radial Package φ10 × 20 mm aluminum can with radial leads and 5 mm lead spacing (±0.5 mm) for through-hole mounting and dense PCB layouts.
• Durability and Temperature Range Endurance specified as 2000 hours at 85°C; operating temperature range −40°C to +85°C for a range of commercial and industrial environments.
• Regulatory RoHS compliant, consistent with environmental directive requirements.

Typical Applications

• Audio — Suitable for audio applications where a 150 µF, 50 V polarized capacitor with low leakage and defined ripple capability is required.
• Audio — Compact radial-lead format (φ10 × 20 mm, 5 mm lead spacing) fits through-hole audio PCB layouts and retrofit designs.
• Audio — Low dissipation factor and controlled leakage current support stable performance in audio power and signal circuits.

Unique Advantages

• Low standby loss: 15 µA leakage current specification helps minimize undesired current draw in idle conditions.
• Efficient AC performance: tanδ = 0.1 at 20°C/120 Hz reduces loss and heating under ripple, improving overall circuit efficiency.
• Defined ripple capability: Rated ripple currents at both low and high frequencies (420 mA @120 Hz, 630 mA @10 kHz) give clear criteria for power-filtering design.
• Compact, serviceable package: φ10 × 20 mm radial can with 5 mm lead spacing supports dense through-hole assemblies and replacement applications.
• Temperature endurance: 2000 hours at 85°C endurance rating and −40°C to +85°C operating range provide predictable life characteristics in elevated-temperature environments.
• RoHS compliant: Meets RoHS requirements for environmentally constrained designs.
