UKL1V331MHD

The UKL1V331MHD is a Nichicon UKL-series aluminum electrolytic capacitor designed for low leakage current in radial-lead format. It delivers 330 µF capacitance at a 35 V rating with a compact φ12.5 × 20 mm can size and 5 mm lead spacing.

Targeted for audio and related electronic applications, this component offers measurable low-loss behavior and controlled ripple capability while operating across –40 °C to 85 °C. Note: Status is End Of Life; please confirm availability when planning purchases.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 35 V and tolerance of -20% to 20%.
• Low Leakage Current — Measured leakage current of 23.1 µA at specified conditions, reflecting the UKL series' low-leakage design.
• Low Dissipation Factor — tanδ = 0.12 (measured at 20 °C, 120 Hz), supporting low-loss signal and power applications.
• Ripple Performance — Low-frequency ripple current of 550 mA (120 Hz) and high-frequency ripple current of 825 mA (10 kHz), suitable for moderate ripple handling in power circuits.
• Endurance & Temperature Range — Rated for 2000 hours at 85 °C; operating temperature range from –40 °C to 85 °C.
• Package & Mounting — Radial lead, polar aluminum can; physical size φ12.5 × 20 mm with 5 mm lead spacing (±0.5 mm).
• Lead & Packaging Options — Available in bulk (no terminal forming) or bag packing for board-level handling.
• Regulatory — RoHS compliant (per provided product information).

Typical Applications

• Audio systems — Suited to audio circuits that require 330 µF at 35 V with low leakage and controlled dissipation factor to maintain signal integrity and power stability.

Unique Advantages

• Measurable low leakage — The low leakage current (23.1 µA) reduces bias drift and improves long-term stability in sensitive circuits.
• Low dissipation for cleaner signals — A tanδ of 0.12 at 20 °C/120 Hz helps minimize loss in audio and low-frequency applications.
• Compact radial package — φ12.5 × 20 mm can size with 5 mm lead spacing enables space-efficient board layouts while retaining necessary capacitance.
• Ripple handling across frequencies — Specified ripple current values at 120 Hz and 10 kHz support both low- and higher-frequency decoupling scenarios.
• Documented endurance — 2000 hours at 85 °C provides a clear reliability baseline for thermal stress planning.
• RoHS compliance — Conforms to RoHS directives as noted in product information.
