UKL1E330MED

The UKL1E330MED is an aluminum electrolytic capacitor from Nichicon’s UKL series designed for low leakage current in a compact radial-lead can. It provides 33 µF capacitance at a 25 V rating in a φ6.3 × 11 mm package with 2.5 mm lead spacing, optimized for space-constrained circuit designs.

Engineered for audio applications, the part delivers defined ripple handling across low and high frequencies (140 mA at 120 Hz, 280 mA at 10 kHz), low leakage current (1.65 µA), and rated endurance of 2000 hours at 85°C, with an operating temperature range of −40°C to 85°C.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a ±20% tolerance, rated at 25 V for common audio and low-voltage power circuits.
• Low Leakage Performance — Specified leakage current of 1.65 µA supports designs that require minimal standby loss and stable bias conditions.
• Ripple Current Capability — Low-frequency ripple rating of 140 mA (120 Hz) and high-frequency rating of 280 mA (10 kHz) for effective smoothing and decoupling across audio bandwidths.
• Compact Radial Package — φ6.3 × 11 mm aluminum can with 2.5 mm lead spacing and radial leads for through-hole mounting in compact assemblies.
• Endurance & Temperature Range — 2000 hours rated life at 85°C and an operating temperature range from −40°C to 85°C for reliable performance in typical ambient conditions.
• Polarized, Through-Hole Mounting — Polarized radial-lead configuration simplifies board layout for power rails and signal coupling in through-hole designs.
• Environmental Compliance — RoHS compliant per product data.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit assembly and stocking preferences.

Typical Applications

• Audio equipment — Suitable for power supply smoothing and decoupling in consumer and professional audio circuits where low leakage is important.
• Audio amplifiers and preamplifiers — Use in biasing and coupling applications that benefit from stable capacitance and low leakage over temperature.
• Compact through-hole designs — Small radial can and 2.5 mm lead spacing make it fit for compact PCB real estate in audio products.

Unique Advantages

• Low standby loss: The specified 1.65 µA leakage current helps maintain low quiescent currents in audio circuits and bias networks.
• Broad ripple handling: Distinct ripple ratings at 120 Hz and 10 kHz (140 mA and 280 mA respectively) provide predictable filtering performance across audible and higher-frequency components.
• Small footprint: φ6.3 × 11 mm can with 2.5 mm lead spacing enables placement in compact through-hole layouts without sacrificing capacitance.
• Designed for audio use: Application designation for audio aligns the part’s electrical characteristics with typical requirements in audio signal and power circuits.
• Durability over temperature: Rated for −40°C to 85°C operation and 2000 hours endurance at 85°C to support sustained performance in typical operating environments.
• RoHS compliant: Conforms to RoHS requirements for environmentally conscious designs.
