UKL1H152KHD

The UKL1H152KHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKL low-leakage family. It delivers 1500 µF capacitance at 50 V in a compact φ18 × 40 mm can with 7.5 mm lead spacing, optimized for power filtering and decoupling in audio equipment and related systems.

Designed for low leakage and sustained ripple performance, this capacitor combines high ripple-current capability with a wide operating temperature range and defined endurance for stable performance in demanding audio power circuits.

Key Features

• Capacitance and Tolerance — 1500 µF nominal capacitance with ±10% tolerance at 120 Hz, 20°C, suitable for bulk energy storage and smoothing.
• Rated Voltage — 50 V working voltage for moderate-voltage power rails and amplifier supply sections.
• Low Leakage Current — Specified leakage current of 150 µA and part of Nichicon’s low-leakage UKL series for stable biasing and low standby loss.
• High Ripple Current Capability — 1.48 A at 120 Hz (low frequency) and 1.702 A at 100 kHz (high frequency) to handle AC ripple and switching noise on power rails.
• Endurance — 2000 hours rated life at 85°C, with specified limits for capacitance change, tan δ and leakage after endurance testing.
• Environmental and Compliance — RoHS compliant construction.
• Mechanical / Mounting — Radial lead, polarized can package; size φ18 × 40 mm with 7.5 mm lead spacing (±0.5 mm) for straightforward through-hole assembly.
• Operating Range — Rated for −40°C to +85°C operation.

Typical Applications

• Audio Power Supply Filtering — Bulk decoupling and smoothing for audio amplifiers and preamplifiers where low leakage and stable bias are important.
• Amplifier Output and Supply Stabilization — Support for amplifier supply rails to reduce ripple and maintain stable operation under varying load currents.
• Audio System Power Modules — Filtering and ripple handling in power modules and DC supply circuits used in audio equipment.

Unique Advantages

• Low Leakage for Stable Biasing: The UKL series’ low-leakage design and the specified 150 µA leakage current minimize bias drift in audio circuits.
• Strong Ripple Handling: Rated ripple currents of 1.48 A (120 Hz) and 1.702 A (100 kHz) support both low-frequency smoothing and high-frequency switching environments.
• Compact Radial Can: φ18 × 40 mm can with standard 7.5 mm lead spacing provides a compact, easy-to-mount solution for through-hole assemblies.
• Defined Endurance: 2000 hours at 85°C gives a clear performance expectation for thermal and lifetime planning.
• Wide Operating Temperature: −40°C to +85°C rating accommodates a broad range of ambient conditions typical in consumer and professional audio gear.
• RoHS Compliant: Meets RoHS directive requirements for lead-free assembly environments.
