UKL1A332KHD

The UKL1A332KHD is a Nichicon UKL series aluminum electrolytic capacitor in a radial-lead, can-style package. It delivers 3.3 mF capacitance at a 10 V rating and is offered as a standard low-leakage-current type targeted for audio applications.

Designed for through-hole assemblies, this component provides verified ripple-current capability across low and high frequencies and an operating temperature range suited for many consumer and audio electronic designs.

Key Features

• Capacitance & Voltage – 3.3 mF (3300 μF) nominal capacitance with a 10 V rated voltage and tolerance of −10% to +10%.
• Low Leakage Current (UKL Series) – Part of Nichicon’s UKL low leakage current series, intended to minimize leakage after application of rated voltage.
• Ripple-Handling Performance – Rated ripple currents of 1.42 A at 120 Hz and 1.633 A at 10 kHz support both power-supply smoothing and higher-frequency decoupling needs.
• Package & Mounting – Radial lead, can-style package with 7.5 mm lead spacing for reliable through-hole PCB mounting and mechanical robustness.
• Temperature & Lifetime – Operating temperature range from −40 °C to 85 °C with a specified lifetime of 2000 hours at 85 °C.
• Compliance – RoHS-compliant construction for regulatory compatibility in applicable regions.

Typical Applications

• Audio equipment – Power supply smoothing and decoupling in audio amplifiers and playback electronics where low leakage supports signal integrity.
• Audio power supply filtering – Bulk energy storage and ripple suppression in audio power rails to maintain stable bias and reduce hum.
• Consumer audio electronics – Through-hole modules and retrofit assemblies that require a compact radial electrolytic with verified ripple and lifetime characteristics.

Unique Advantages

• Low leakage design: Being part of the UKL series lowers leakage current after voltage application, aiding long-term bias stability in audio circuits.
• Dual-frequency ripple capability: Specified ripple currents at 120 Hz and 10 kHz provide data-driven assurance for both mains-frequency smoothing and higher-frequency decoupling tasks.
• Through-hole, robust mounting: Radial lead and can package with 7.5 mm lead spacing simplifies PCB layout for through-hole assembly and mechanical stability.
• Compact footprint: Physical dimensions (L: 3.05 cm × D: 1.6 cm) make it suitable for space-constrained audio modules and retrofit designs.
• Rated lifetime at elevated temperature: 2000 hours at 85 °C offers a published endurance metric for thermal reliability planning.
• Regulatory readiness: RoHS compliance supports inclusion in products requiring restricted-substance conformance.
