UKL1V150KDD

The UKL1V150KDD is an aluminum electrolytic capacitor from Nichicon’s UKL series engineered for low leakage current in a compact radial‑lead can. With a rated capacitance of 150µF at 35V and a φ10×16mm package, it targets space‑constrained power and signal circuits where low loss and controlled ripple handling are required.

Designed for applications operating across –40°C to +85°C and specified for 2000 hours at 85°C, this unit offers predictable endurance and RoHS compliance for regulated electronic systems.

Key Features

• Low Leakage Current — Specified leakage current of 1.05 µA, enabling reduced standby loss and improved performance in low‑current circuits.
• Electrical Performance — 150µF capacitance at 35V with ±10% tolerance (K). Measured tanδ of 0.12 at 20°C, 120Hz for the φ10×16 case size, supporting low loss in filtering and decoupling roles.
• Ripple Current Capability — Rated ripple current of 85 mA at 120Hz (low frequency) and 170 mA at 10 kHz (high frequency), suitable for moderate AC ripple rejection and smoothing tasks.
• Package and Mounting — Radial lead, can‑style package (φ10×16mm) with 2 mm lead spacing (±0.5 mm tolerance) for through‑hole PCB layouts and hand‑assembled or automated insertion processes.
• Reliability & Lifetime — Endurance rating of 2000 hours at 85°C with specified restoration characteristics after testing, providing predictable aging for maintenance planning.
• Environmental Compliance — RoHS‑compliant construction.
• Availability Status — Product status: End Of Life. The UKL series is noted as scheduled for discontinuation and is not recommended for new designs.

Typical Applications

• Audio circuits — Suited to audio front‑end and power rail filtering where low leakage and low loss (tanδ 0.12) help maintain signal integrity and reduce noise.

Unique Advantages

• Low standby loss: Leakage current specified at 1.05 µA helps minimize quiescent current draw in battery‑sensitive and low‑power systems.
• Compact radial can: φ10×16mm form factor with 2 mm lead spacing fits tight through‑hole layouts while retaining adequate capacitance for smoothing and decoupling.
• Measured low dissipation: tanδ = 0.12 (20°C, 120Hz) for the φ10×16 case supports efficient energy handling and reduced self‑heating in AC ripple situations.
• Frequency‑aware ripple performance: Rated ripple currents specified for both 120Hz and 10kHz frequencies (85 mA and 170 mA respectively), enabling designers to assess behavior across low and high ripple conditions.
• Predictable endurance: 2000 h life at 85°C provides a defined reliability baseline for thermal lifecycle planning.
• Regulatory readiness: RoHS compliance simplifies use in regulated product lines.

Why Choose UKL1V150KDD?

UKL1V150KDD combines low leakage and low dissipation in a compact φ10×16 radial package, making it a practical choice for legacy or replacement needs in audio and other moderate‑power electronic designs that require stable capacitance and controlled ripple handling. Its 2000‑hour endurance at 85°C and RoHS compliance provide predictable performance and regulatory alignment for deployed systems.

Note that this part is marked End Of Life and the UKL series is scheduled for discontinuation; it is therefore best suited for existing designs, spares, or where form‑fit‑function replacement is acceptable rather than for new product introductions.
