UKT0J331MED

The UKT0J331MED is a radial-lead aluminum electrolytic capacitor designed for audio equipment and other electronics requiring compact energy storage and stable performance across a wide temperature range. This polarized, radial-can capacitor delivers 330 µF capacitance with ±20% tolerance and is optimized for applications that demand reliable ripple handling and high-temperature endurance.

Key Features

• Capacitance & Tolerance — 330 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C, suitable for energy smoothing and decoupling in audio circuits.
• Rated Voltage — 16 V rated voltage for low-voltage analog and power-supply stages.
• Loss Angle (tan δ) — tanδ 0.22 (max.) measured at 20°C, 120 Hz, providing a specified dissipation characteristic for design margining.
• Ripple Current Capability — Low-frequency ripple current rated at 265 mA (105°C/120 Hz) and high-frequency ripple current listed at 397.5 mA, supporting applications with both mains-frequency and higher-frequency ripple components.
• Leakage Current — 52.8 µA leakage (specified condition: 20°C, after defined test interval), aiding predictable bias behavior in powered circuits.
• Wide Temperature & Endurance — Operating range −55°C to +105°C with 1000 hours endurance at 105°C for elevated-temperature reliability.
• Compact Radial Package — φ8 × 11.5 mm can with 3.5 mm lead spacing (±0.5 mm), available in bulk or bag packing for straightforward through-hole assembly.
• Quality & Compliance — AEC-Q200 rating and RoHS compliance noted in specifications for quality-driven designs.

Typical Applications

• Audio Electronics — DC blocking, power-supply smoothing and reservoir capacitor in amplifiers, mixers, and other audio equipment where stable capacitance and controlled dissipation are required.
• Power Supply Filtering — Input and output smoothing on low-voltage regulators and DC-DC converters in compact designs.
• Portable and Consumer Devices — Bulk energy storage and decoupling in small form-factor boards that need a radial through-hole part.

Unique Advantages

• Wide operating temperature span: −55°C to +105°C supports designs that experience broad temperature extremes without derating component selection.
• Defined high-temperature endurance: 1000 hours at 105°C gives a clear reliability baseline for thermal-stressed applications.
• High ripple capability: 265 mA at 120 Hz and 397.5 mA at high frequency help manage both mains-frequency and higher-frequency ripple currents in power stages.
• Compact radial form factor: φ8×11.5 mm can size with 3.5 mm lead spacing fits space-constrained through-hole layouts while providing practical capacitance for audio and power smoothing tasks.
• Quality and compliance: AEC-Q200 recognition and RoHS compliance align with quality-focused manufacturing and environmental requirements.
