UKL1A332MHD

The UKL1A332MHD is a Nichicon UKL series aluminum electrolytic capacitor offering low leakage current in a radial-lead can. It provides 3,300 µF capacitance at a 10 V rating with polarization and is designed for applications where low leakage and substantial ripple handling are required.

Key electrical characteristics include a specified leakage current of 66 µA, low-frequency ripple current of 1.42 A (120 Hz) and high-frequency ripple current of 1.633 A (10 kHz). The part is rated for operation from –40°C to 85°C with an endurance of 2,000 hours at 85°C. Status: End Of Life — not recommended for new designs.

Key Features

• Capacitance and Voltage — 3,300 µF nominal capacitance with ±20% tolerance at a rated voltage of 10 V, suitable for bulk energy storage in polarized circuits.
• Low Leakage Design — Specified leakage current of 66 µA to minimize standby losses in low-current or precision circuits.
• Ripple Current Handling — Rated for 1.42 A at 120 Hz (low frequency) and 1.633 A at 10 kHz (high frequency) to support power filtering and decoupling under varying ripple conditions.
• Reliability and Endurance — 2,000 hours lifetime at 85°C with post-test limits on capacitance change and leakage consistent with endurance specifications.
• Mechanical and Mounting — Radial-lead can package, size φ16 × 30.5 mm length, lead spacing 7.5 mm (±0.5 mm), supplied in bulk or bag packing for through‑hole assembly.
• Operating Range and Compliance — Rated for –40°C to 85°C and compliant with RoHS requirements.

Typical Applications

• Audio — Used in audio equipment where low leakage and substantial capacitance are needed for power supply smoothing and stable biasing in polarized circuits.

Unique Advantages

• Low standby current footprint — The specified 66 µA leakage current helps reduce quiescent losses in low-power or precision audio circuits.
• Dual-frequency ripple capability — Defined ripple ratings at both 120 Hz and 10 kHz provide clear guidance for designers handling low- and high-frequency ripple scenarios.
• Proven endurance specification — 2,000 hours at 85°C offers a measurable reliability baseline for thermal-stressed applications.
• Compact radial package — φ16 × 30.5 mm can with 7.5 mm lead spacing fits through-hole assemblies where space and mechanical stability are factors.
• Regulatory compliance — RoHS-compliant construction supports regulatory needs for lead‑free manufacturing.
