UKL0J332MHD

The UKL0J332MHD is a Nichicon UKL series aluminum electrolytic capacitor in a radial-lead can, offering 3300 µF capacitance at a 6.3 V rating. It targets applications that require high bulk capacitance with low leakage current in a compact φ16 × 25 mm package.

Key electrical characteristics include low leakage current, defined tanδ, and robust ripple-current capability at both low and high frequencies. The capacitor is RoHS compliant. Status: End Of Life.

Key Features

• Capacitance & Rated Voltage — 3300 µF (3.3 mF) nominal capacitance with a 6.3 V rated voltage and tolerance of −20% to +20%.
• Low Leakage Current — Designed as part of Nichicon’s low leakage UKL series; measured leakage current for this part is 41.58 µA.
• Loss Tangent (tanδ) — tanδ = 0.25 measured at 20°C, 120 Hz, providing a quantified dissipation characteristic for AC and ripple conditions.
• Ripple Current Capability — Rated low-frequency ripple current of 1.27 A (120 Hz) and high-frequency ripple capability of 1.46 A (10 kHz), suitable for filtering and decoupling in power chains.
• Endurance and Temperature Range — 2000 hours life at 85°C with an operating temperature range of −40°C to +85°C.
• Package & Mounting — Radial lead, polarized can package with dimensions φ16 × 25 mm, lead spacing 7.5 mm (±0.5 mm), available in bulk (no terminal forming) or bag packing.
• Compliance — RoHS compliant.

Typical Applications

• Audio equipment — Provides high-value bulk capacitance and low leakage for power supply smoothing, coupling, and decoupling in compact audio devices.
• Small power supplies — Useful for local energy storage and ripple suppression on low-voltage rails where 6.3 V rating and elevated ripple currents are required.
• Consumer electronics — Fits compact PCB layouts that demand substantial capacitance in a radial can format (φ16 × 25 mm) and proven endurance at elevated temperature.

Unique Advantages

• High bulk capacitance in a compact can: 3300 µF in a φ16 × 25 mm package reduces board area compared with multiple smaller capacitors.
• Measured low leakage: Low leakage current (41.58 µA) helps preserve DC bias and minimizes standby loss in sensitive circuits.
• Defined AC performance: Specified tanδ (0.25 at 120 Hz, 20°C) and frequency-differentiated ripple current figures support predictable behavior under ripple loading.
• Long endurance at rated temperature: 2000 hours at 85°C gives a quantified lifetime expectation for thermal stress conditions.
• Radial-lead convenience: Standard lead spacing (7.5 mm) and polarized mounting simplify through-hole assembly and replacement workflows.
• Regulatory compliance: RoHS status ensures conformance with lead-free material requirements.
