UKL1J330MPD

The UKL1J330MPD is a radial-leaded aluminum electrolytic capacitor from Nichicon’s UKL series designed for applications that require low leakage and compact axial packaging. With a rated capacitance of 33 µF at 63 V, this polarized capacitor targets audio and general-purpose power-filtering uses where stable performance across a broad temperature range and defined ripple handling are important.

Built for reliability in constrained assemblies, the part combines low-frequency and high-frequency ripple handling with a 2,000-hour endurance at 85°C, making it suitable for designs with steady thermal and electrical demands.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a rated voltage of 63 V and a tolerance of −20% to +20% for predictable decoupling and bulk-storage behavior.
• Low Leakage Current — Low-leakage construction with a measured leakage current of 4.158 µA (measured condition provided), supporting designs that require minimal standby drain.
• Loss Tangent (tan δ) — tan δ of 0.07 measured at 20°C, 120 Hz, ensuring controlled dissipation for audio and analogue circuits where loss characteristics matter.
• Ripple Current Handling — Rated low-frequency ripple current of 170 mA (120 Hz) and high-frequency ripple current of 340 mA (10 kHz) for improved smoothing across a range of operating frequencies.
• Thermal & Lifetime — Operating temperature range −40°C to +85°C with an endurance rating of 2,000 hours at 85°C, providing predictable life performance under rated stress.
• Radial Lead Package — Compact radial can package (φ8 × 11.5 mm) with 3.5 mm lead spacing (±0.5 mm) for through-hole mounting and simple PCB placement; available in bulk or bag packing.
• RoHS Compliant — Manufactured to meet RoHS requirements for regulated substance control.

Typical Applications

• Audio Electronics — Used for coupling, decoupling, and power-supply smoothing in audio preamplifiers and signal-path circuits where low leakage and controlled loss are important.
• Power Filtering — Bulk storage and ripple filtering on DC rails in low- to mid-power supplies, leveraging the specified low- and high-frequency ripple ratings.
• General Embedded Systems — Decoupling and local energy storage in compact through-hole designs requiring radial lead components and reliable performance across −40°C to +85°C.

Unique Advantages

• Measured Low Leakage — Low measured leakage current supports lower standby currents and improved DC bias stability for sensitive circuits.
• Frequency Versatility — Separate ripple current specifications for 120 Hz and 10 kHz provide clarity for designers optimizing for both mains-derived and higher-frequency switching ripple.
• Compact Through-Hole Form — φ8 × 11.5 mm can with 3.5 mm lead spacing provides a small footprint radial-lead solution that simplifies PCB layout in space-constrained designs.
• Predictable Endurance — 2,000-hour rating at 85°C gives designers a defined life expectation for thermal-stressed applications.
• Clear Electrical Characterization — Specified tan δ and leakage figures measured at 20°C, 120 Hz allow direct comparison and engineering trade-offs during component selection.
