UKT1V220MDD

The UKT1V220MDD from Nichicon is a miniature aluminum electrolytic capacitor in a radial lead can, designed for use in audio equipment. It provides 22 µF capacitance at a 35 V rating with a compact φ5 × 11 mm case and 2 mm lead spacing for dense PCB layouts.

This part delivers defined electrical performance for audio designs, including a measured tanδ of 0.16 (120 Hz, 20 °C), low- and high-frequency ripple current specifications, and an operating temperature range of −55 °C to 105 °C. Note: this part is listed as End Of Life.

Key Features

• Capacitance & Voltage: 22 µF nominal capacitance with a 35 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Electrical Losses: tanδ 0.16 measured at 120 Hz and 20 °C, providing predictable loss characteristics for audio circuits.
• Ripple Current Capability: Low-frequency ripple current 61 mA at 120 Hz and high-frequency ripple current 122 mA at 10 kHz for handling both power and switching-related ripple in audio supplies.
• Leakage Current: Measured leakage current of 23.1 µA, supporting low-noise and low-bias applications.
• Temperature & Endurance: Wide operating range from −55 °C to 105 °C and rated for 1000 hours at 105 °C per the datasheet endurance conditions.
• Package & Mounting: Radial lead, can-style package (φ5 × 11 mm) with 2.0 mm lead spacing (±0.5 mm) for through-hole assembly; available in bulk or bag packing (no terminal forming).
• Compliance & Qualification: RoHS compliant and carries AEC-Q200 rating as specified in the product data.

Typical Applications

• Audio equipment: Intended for general audio equipment designs where compact radial electrolytic capacitors are required.
• Audio PCB assemblies: Suited to small-form-factor audio boards that require through-hole radial components with tight lead spacing.
• Miniature audio modules: Appropriate for module-level use in audio subsystems that need a combination of compact size and defined temperature/endurance performance.

Unique Advantages

• Compact form factor: φ5 × 11 mm can and 2 mm lead spacing enable tighter component placement on through-hole audio PCBs.
• Wide temperature range: −55 °C to 105 °C operation supports designs exposed to broad environmental conditions.
• Defined endurance: Rated 1000 hours at 105 °C, allowing designers to evaluate long‑term behavior under elevated temperature stress.
• Frequency-aware ripple handling: Specified ripple current at both 120 Hz and 10 kHz (61 mA and 122 mA respectively) helps match capacitor selection to audio power and switching conditions.
• Low leakage: 23.1 µA leakage current supports low-noise and low-bias circuit requirements common in audio paths.
• AEC-Q200 rating: Supplier-stated AEC-Q200 qualification provides additional reliability data referenced in the product information.
