UKT1A223MRD

The UKT1A223MRD is a miniature aluminum electrolytic capacitor from Nichicon's UKT series, designed for audio equipment applications. It is a radial-lead, polarized can-style capacitor providing 22 mF nominal capacitance at a 10 V rating.

Engineered for robust operation, the device offers a wide operating temperature range and defined ripple-current performance, making it suitable for audio designs that require reliable bulk capacitance and sustained ripple handling in a compact through-hole package.

Key Features

• Electrical performance: 22 mF capacitance with a 10 V rated voltage and polarization suitable for typical audio power and coupling applications.
• Ripple-current capability: Specified ripple current of 2.65 A at 120 Hz and 3.047 A at 10 kHz, supporting sustained AC loading in audio power circuits.
• Wide temperature and endurance: Rated for operation from −55 °C to 105 °C with a lifetime specification of 1000 hours at 105 °C.
• Package and mounting: Radial lead, can-style package with 1.0 cm lead spacing and physical dimensions L: 4 × D: 2.2 cm for straightforward through-hole assembly.
• Tolerance and polarization: Capacitance tolerance of −20% to +20% and polarized construction for correct orientation in DC circuits.
• AEC qualification and environmental compliance: AEC-Q200 rated and RoHS compliant for applications requiring recognized passive component qualification and lead-free compliance.
• Identification: Marked with black lettering on a pearl-blue sleeve for clear part identification.

Typical Applications

• Audio equipment: Designed for use in audio devices where 22 mF at 10 V bulk capacitance and reliable ripple handling are required.
• Amplifier power stages: Suitable for power supply smoothing and decoupling in amplifier circuits that demand sustained ripple-current performance.
• Consumer and professional audio systems: Fits through-hole assemblies where a compact, long-life polarized electrolytic capacitor is needed.

Unique Advantages

• High ripple-current handling: Clear ripple specifications at both low and high frequencies (2.65 A at 120 Hz, 3.047 A at 10 kHz) reduce thermal stress in audio power applications.
• Wide operating range with proven endurance: −55 °C to 105 °C operation and a 1000-hour life at 105 °C offer predictable long-term performance in demanding environments.
• AEC-Q200 qualification: Provides an additional level of quality assurance for designs that reference AEC passive-component qualification.
• Through-hole robustness: Radial lead and can package simplify manual assembly and repair while delivering mechanical stability on PCBs.
• RoHS compliant: Meets lead-free environmental requirements for modern electronics manufacturing.
• Compact form factor: Small footprint (L: 4 × D: 2.2 cm) and 1.0 cm lead spacing balance capacitance with space-constrained board layouts.
