UKT0J220MDD

The UKT0J220MDD is a radial-lead aluminum electrolytic capacitor engineered for general audio equipment and applications requiring stable performance across a wide temperature range. It provides 22 µF capacitance at a 6.3 V rating in a compact φ5 × 11 mm can with 2 mm lead spacing.

Designed for durability and predictable behavior in demanding environments, the UKT0J220MDD combines low leakage, defined ripple-current ratings, and a 1000-hour endurance at 105°C to support reliable power decoupling and smoothing in audio circuits.

Key Features

• Electrical Performance — 22 µF nominal capacitance with ±20% tolerance and a rated voltage of 6.3 V, suitable for low-voltage audio circuits and power decoupling.
• Ripple Current Ratings — Specified ripple current of 45 mA at 120 Hz and 90 mA at 10 kHz, providing defined AC handling for low- and high-frequency audio power conditions.
• Low Leakage — Leakage current specified at 4.158 µA, supporting low-bias-loss applications and maintaining circuit bias stability.
• Reliability & Endurance — 1000-hour rated lifetime at 105°C, with performance characterized after endurance testing to help ensure long-term stability under elevated temperature stress.
• Wide Temperature Range — Operates from −55°C to 105°C, enabling use across varied environmental conditions encountered in audio equipment.
• Package & Mounting — Radial-lead, can-style package (φ5 × 11 mm) with 2 mm lead spacing (±0.5 mm tolerance), supplied Bulk/Bag (no terminal forming) for through-hole assembly.
• Qualification & Compliance — AEC-Q200 rated and RoHS compliant, reflecting qualification and lead-free regulatory status as listed in the product data.

Typical Applications

• Audio Equipment — Intended for general audio equipment use, the UKT0J220MDD supports signal coupling, smoothing and power decoupling tasks where stable capacitance, low leakage and defined ripple handling are required.

Unique Advantages

• Compact footprint: Small φ5 × 11 mm can size enables space-efficient designs for dense PCBs and compact audio modules.
• Defined ripple capability: Separate ripple ratings at 120 Hz and 10 kHz allow designers to size capacitors based on both low- and high-frequency AC stress.
• Low leakage current: 4.158 µA leakage helps maintain bias levels and reduces quiescent loss in sensitive audio circuits.
• Wide operating temperature: −55°C to 105°C rating supports reliable operation across harsh ambient and thermal conditions.
• Long endurance at elevated temperature: 1000 hours at 105°C provides predictable aging characteristics for product life-cycle planning.
• Industry qualification and compliance: AEC-Q200 rating and RoHS compliance simplify inclusion in qualified designs and regulated markets.
