UKL1V220KED

The UKL1V220KED from Nichicon is a low-leakage aluminum electrolytic capacitor in a compact radial-lead can. It offers 22 µF capacitance at a 35 V rating and is part of the UKL low-leakage series designed for electronic applications where leakage, ripple handling and compact size matter.

Targeted use cases include audio circuitry and related consumer electronics where tight capacitance tolerance, low leakage and defined ripple performance support stable power and signal paths in compact assemblies.

Key Features

• Capacitance & Tolerance — 22 µF nominal capacitance with ±10% tolerance for predictable frequency response in filtering and decoupling roles.
• Voltage Rating — Rated for 35 V to support common low-voltage audio and analog power rails.
• Low Leakage Current — Measured leakage current of 1.54 µA to minimize bias drift and reduce standby loss in sensitive circuits.
• Ripple Current Performance — 110 mA at 120 Hz (low frequency) and 220 mA at 10 kHz (high frequency) to handle both power-supply smoothing and higher-frequency decoupling demands.
• Endurance — Rated life of 2000 hours at 85°C, suitable for sustained operation within the specified temperature range.
• Operating Temperature — Specified for −40°C to 85°C to cover typical ambient and indoor application environments.
• Compact Radial Package — Physical size φ6.3 × 11 mm with 2.5 mm lead spacing (±0.5 mm), radial-lead mounting for through-hole assemblies and prototyping.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible procurement and handling.
• RoHS Compliant — Manufactured in compliance with RoHS requirements.

Typical Applications

• Audio equipment — Used for power-supply smoothing, decoupling and local energy storage in audio preamplifiers, DACs and headphone amplifiers where low leakage preserves signal integrity.
• Analog circuits — Provides stable capacitance and low leakage for bias networks and filter stages in compact analog designs.
• Consumer electronics — Compact radial package fits space-constrained PCBs for general decoupling and smoothing tasks in small appliances and portable devices.

Unique Advantages

• Low leakage for stable biasing — The specified 1.54 µA leakage current helps maintain DC offsets and reduces drift in sensitive audio and analog circuits.
• Dual-frequency ripple capability — Rated ripple currents at both 120 Hz (110 mA) and 10 kHz (220 mA) address low-frequency smoothing and higher-frequency decoupling with the same component.
• Compact footprint — φ6.3 × 11 mm can and 2.5 mm lead spacing enable placement in tight board layouts while retaining through-hole robustness.
• Designed endurance — 2000 hours at 85°C provides predictable performance over extended operating periods at elevated temperatures.
• Consistent tolerance — ±10% capacitance tolerance supports repeatable circuit behavior across production units.
• RoHS compliance — Meets environmental regulations for lead-free assembly requirements.
