Key Features

• Capacitance & Voltage — 33 µF rated capacitance with a 35 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C).
• Low Loss — tan δ = 0.16 (specified at the part’s rated voltage), supporting stable AC performance in audio circuits.
• Ripple Current Performance — 75 mA at 120 Hz (low frequency) and 150 mA at 10 kHz (high frequency), enabling effective smoothing and decoupling across audio bandwidths.
• Low Leakage Current — 34.65 µA leakage current, supporting low-bias drift and stable DC performance after installation.
• Wide Temperature & Endurance — Operating range −55°C to 105°C with a rated life of 2000 hours at 105°C.
• Package & Mounting — Radial lead can, compact size (L: 1.1 × D: 0.5 cm), 2 mm lead spacing; supplied in bulk/bag packing.
• AEC Qualification — AEC‑Q200 rated, reflecting series-level qualification for reliability-critical applications.

Typical Applications

• High‑grade Audio Amplifiers — Power supply smoothing and decoupling in amplifier stages where low loss and low leakage aid audio fidelity.
• Studio and Consumer Hi‑Fi Equipment — Use in power rails and signal-chain support components for consistent performance across temperature extremes.
• Audio Preamplifiers and Signal Conditioning — Local energy storage and filtering to maintain stable biasing and reduce hum/noise in sensitive circuits.

Unique Advantages

• Targeted for Audio Performance — Specified tan δ and ripple current figures make the part well-suited to audio-focused power and signal tasks.
• Wide Operating Temperature — −55°C to 105°C capability enables deployment in environments with significant thermal variation.
• Long Endurance at Elevated Temperature — 2000 hours at 105°C provides predictable lifetime behavior for long‑running equipment.
• Compact Radial Package — Small φ5×11 mm can and 2 mm lead spacing allow space-constrained board layouts without sacrificing performance.
• AEC‑Q200 Qualification — Series-level AEC‑Q200 rating supports designs that require recognized component reliability standards.
• Low Leakage and Low Loss — Measured leakage and tan δ values help maintain DC stability and minimize audible artifacts in audio circuits.

Why Choose UKA1V330MDD?
