UKL1H330MPD

The UKL1H330MPD is a Nichicon UKL-series aluminum electrolytic capacitor in a compact radial‑lead can. It delivers 33 µF nominal capacitance at a 50 V rating with low leakage and controlled loss tangent, targeted for audio‑focused circuits and other designs that require stable biasing and moderate ripple handling.

Designed for through‑hole mounting, this φ8 × 11.5 mm component offers a 3.5 mm lead spacing and a rated operating range of −40 °C to 85 °C with 2000 hours endurance at 85 °C.

Key Features

• Electrical Core 33 µF nominal capacitance with a tolerance of −20% to +20% and a rated voltage of 50 V, suitable for a variety of DC bias and decoupling roles.
• Low Leakage Specified leakage current of 3.3 µA under rated conditions, supporting stable bias points and minimizing DC loss.
• Low Loss Tangent tanδ of 0.08 (measured at 20 °C, 120 Hz) for reduced dielectric loss in audio and low‑frequency signal paths.
• Ripple Handling Low‑frequency ripple current rated at 165 mA (120 Hz) and high‑frequency ripple current rated at 330 mA (10 kHz), enabling use in both power filtering and higher‑frequency decoupling scenarios.
• Reliability & Lifetime Endurance specified as 2000 hours at 85 °C with the rated voltage applied, allowing predictable life planning for thermal environments up to 85 °C.
• Mechanical & Mounting Radial lead, can‑style package with φ8 × 11.5 mm dimensions and 3.5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for through‑hole assembly.
• Compliance RoHS compliant as part of the UKL series.

Typical Applications

• Audio equipment power filtering Low leakage and low tanδ support clean power supply decoupling in preamplifiers and other analog audio stages.
• Bias stabilization in audio circuits Low leakage current helps maintain stable DC bias in amplifier and signal‑chain circuits.
• Compact through‑hole designs Small φ8 × 11.5 mm can and standard 3.5 mm lead spacing suit space‑constrained legacy boards and repair applications.

Unique Advantages

• Low leakage for stable DC operation: The specified 3.3 µA leakage current helps preserve bias points and reduce DC‑level drift in sensitive circuits.
• Measured low loss (tanδ = 0.08): Controlled dielectric loss at 120 Hz supports lower noise contribution in audio paths.
• Dual‑band ripple capability: Rated ripple currents at 120 Hz and 10 kHz demonstrate suitability for both low‑frequency smoothing and higher‑frequency decoupling.
• Compact radial package: φ8 × 11.5 mm can with 3.5 mm lead spacing fits many through‑hole form factors while keeping PCB footprint small.
• Predictable lifetime: 2000 hours endurance at 85 °C enables reliable thermal life planning for moderate‑temperature applications.
• RoHS compliant: Conforms to RoHS requirements as documented for the UKL series.
