UKT0J221MED

The UKT0J221MED is a radial-lead aluminum electrolytic capacitor designed for general audio equipment and related electronics. It delivers 220 µF capacitance at a 6.3 V rating in a compact φ6.3 × 11 mm can, optimized for power filtering, decoupling and smoothing in compact audio circuits.

Engineered for reliability across a wide temperature range, this polarized capacitor offers long endurance (1000 hours at 105°C), measurable low leakage, and frequency-aware ripple capability for low- and high-frequency audio power rails.

Key Features

• Capacitance and Voltage: 220 µF rated capacitance at 6.3 V for power-supply decoupling and smoothing in low-voltage audio circuits.
• Electrical Loss (tan δ): tanδ = 0.3 measured at 20°C, 120 Hz, providing a specified loss characteristic for predictable frequency response in audio paths.
• Ripple Current Capability: Rated ripple performance of 160 mA at 120 Hz (low frequency) and 240 mA at 10 kHz (high frequency) to handle both mains-frequency and higher-frequency switching/ripple components.
• Low Leakage Current: Specified leakage current of 41.58 µA to minimize standby/power-down losses in sensitive audio and low-current designs.
• Wide Operating Temperature: Specified for −55°C to +105°C, suitable for equipment exposed to broad ambient conditions.
• Robust Endurance: 1000 hours endurance at 105°C, with defined limits for capacitance change, tanδ and leakage after the endurance test.
• Package and Mounting: Radial lead can (φ6.3 × 11 mm) with 2.5 mm lead spacing (±0.5 mm) for through-hole, serviceable PCB layouts; available in bulk (no terminal forming) or bag packing.
• AEC Qualification: AEC-Q200 qualified, providing an additional qualification reference for reliability-focused designs (see manufacturer details for scope).

Typical Applications

• General Audio Equipment — Power-supply smoothing, decoupling and reservoir duties in compact audio amplifiers, preamps and consumer audio devices.
• Low-Voltage Power Rails — Bulk decoupling and local energy storage on 6.3 V rails to stabilize transient loads and reduce audible artifacts.
• Signal Conditioning Support — Use where controlled loss (tanδ) and low leakage help maintain signal integrity in audio-related circuits.

Unique Advantages

• Compact footprint: φ6.3 × 11 mm radial can provides sizable capacitance in a small package for space-constrained PCB designs.
• Dual-frequency ripple handling: Specified ripple current at both 120 Hz and 10 kHz supports performance across mains-frequency and high-frequency switching environments.
• Wide temperature tolerance: −55°C to +105°C rating and 1000-hour endurance at 105°C for stable performance in demanding ambient conditions.
• Low standby loss: Measured leakage current of 41.58 µA helps reduce quiescent current draw in low-power audio systems.
• Polarized radial lead format: Through-hole mounting with defined 2.5 mm lead spacing simplifies replacement, prototyping and serviceability.
• Manufacturer qualification: AEC-Q200 qualification noted by the manufacturer for designers requiring that level of component assessment.
