UKA0J331MED

The UKA0J331MED is a radial-lead aluminum electrolytic capacitor designed for audio and general-purpose electronic applications. It delivers 330 µF capacitance at a rated voltage of 6.3 V in a compact φ6.3 × 11 mm can with 2.5 mm lead spacing.

This part combines a low-loss construction (tan δ 0.30), specified leakage current, and defined ripple-current performance across low and high frequencies, with an operating temperature range of –55°C to 105°C and a 2000-hour endurance at 105°C. Note: this part is listed as End Of Life.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at 6.3 V rated voltage, ±20% tolerance for standard supply decoupling and energy storage tasks.
• Low-loss Performance — Tangent of loss angle (tan δ) specified at 0.30 (120 Hz), supporting low distortion in audio circuits where ESR-related losses matter.
• Ripple Current Capability — Rated ripple currents of 195 mA at 120 Hz and 292.5 mA at 10 kHz, useful for filtering and smoothing in power rails across frequency ranges.
• Controlled Leakage — Specified leakage current of 62.37 µA for predictable bias behavior and long-term stability after voltage application.
• Wide Temperature & Endurance — Operating from –55°C to 105°C with a lifetime rating of 2000 hours at 105°C, enabling reliable operation in thermally demanding environments.
• Package & Mounting — Radial-lead can in φ6.3 × 11 mm size with 2.5 mm lead spacing for through-hole mounting and mechanical robustness.
• AEC Qualification — AEC-Q200 rated, supporting use in designs that require passive-component AEC qualification.
• Packing — Supplied in bulk (no terminal forming) or bag packing per product packaging options.

Typical Applications

• Audio equipment — Use as supply decoupling and smoothing capacitors in preamplifiers, DACs, and other audio circuits where low tan δ helps maintain signal integrity.
• Power filtering — Bulk and local filtering on low-voltage rails (6.3 V) to reduce ripple and stabilize regulators in compact power supplies.
• Embedded electronics — General-purpose energy storage and decoupling in through-hole PCB designs requiring a compact radial can capacitor.

Unique Advantages

• Compact energy density — 330 µF in a φ6.3 × 11 mm can provides significant capacitance for space-constrained through-hole designs.
• Frequency-spanning ripple capability — Specified ripple currents at both 120 Hz and 10 kHz help designers size capacitors for mixed-frequency power environments.
• Predictable leakage behavior — A defined leakage current figure simplifies bias and startup calculations in precision and low-current circuits.
• Designed for elevated temperatures — 2000-hour endurance at 105°C and a –55°C lower limit support use across a broad ambient range and thermal stress conditions.
• AEC-Q200 rated — Provides an added level of component qualification for designs that require AEC passive-component assessment.
• Through-hole robustness — Radial-lead can and standard 2.5 mm lead spacing simplify prototyping, repair, and mechanical retention on PCBs.
