UKT1A220MDD

The UKT1A220MDD is a Nichicon aluminum electrolytic capacitor in a radial-lead can, offering 22 µF capacitance at a 10 V rating. It belongs to the UKT series, which is described for general audio equipment and wide temperature range operation.

Designed for through-hole assemblies and compact audio modules, this part combines a small φ5 × 11 mm package and 2 mm lead spacing with specified endurance and ripple characteristics for engineering-grade integration.

Key Features

• Capacitance & Tolerance — 22 µF nominal with a tolerance of -20%~20% (measured at 120 Hz, 20°C).
• Rated Voltage — 10 V DC rating suitable for low-voltage audio circuits and modules.
• Dissipation Factor (tan δ) — tanδ = 0.26 measured at 20°C and 120 Hz, provided for design validation of loss and thermal behavior.
• Ripple Current Capability — Low-frequency ripple current 45 mA at 120 Hz and high-frequency ripple current 90 mA at 10 kHz, enabling predictable ripple handling across a range of frequencies.
• Leakage Current — Specified leakage current of 6.6 µA for predictable bias conditions in circuits.
• Temperature & Endurance — Wide operating temperature range of -55°C to 105°C and rated endurance of 1000 hours at 105°C.
• Package & Mounting — Radial lead, can-style package with dimensions φ5 × 11 mm and 2 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• Reliability Rating — Built to an AEC-Q200 rating for enhanced quality and reliability verification.

Typical Applications

• Audio equipment — Suited for general audio applications where a 22 µF, 10 V polarized radial-lead capacitor is required.
• Compact consumer audio modules — Small φ5 × 11 mm package and 2 mm lead spacing make it suitable for tight through-hole PCB layouts in compact audio assemblies.
• Professional audio circuitry — Wide -55°C to 105°C operating range and 1000 h endurance at 105°C support robust performance in demanding audio environments.

Unique Advantages

• Compact footprint for tight designs: φ5 × 11 mm can and 2 mm lead spacing optimize board space in small audio modules.
• Specified ripple performance: Rated ripple currents of 45 mA (120 Hz) and 90 mA (10 kHz) provide clear parameters for power and signal path design.
• Predictable leakage and loss figures: Leakage current (6.6 µA) and tanδ (0.26 at 20°C/120 Hz) are documented for accurate bias and thermal planning.
• Wide temperature and endurance rating: -55°C to 105°C range with 1000 hours endurance at 105°C supports long-term reliability in varied environments.
• AEC-Q200 reliability indicator: The AEC-Q200 rating offers an added level of qualification for designs where documented reliability metrics are required.
• Assembly-friendly packaging: Available in bulk (no terminal forming) or bag packing to accommodate manual or low-volume production workflows.
