Designed for use where stable capacitance, controlled loss angle and reliable ripple handling are required, the UKA1H330MDD supports audio power circuitry and related applications while providing extended life at elevated temperatures.

Key Features

• Rated Voltage — 50 V rating suitable for many audio power-rail applications.
• Capacitance and Tolerance — 33 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C.
• Temperature Range — Wide category temperature range from −55°C to +105°C for use in demanding thermal environments.
• Low Loss for Audio — Tangent of loss angle (tan δ) of 0.14 measured at 120 Hz and 20°C, supporting low-loss performance in audio circuits.
• Ripple Current Capability — Rated low-frequency ripple current of 90 mA at 120 Hz and high-frequency ripple current of 180 mA at 10 kHz to address both power-supply and high-frequency demands.
• Leakage Current — Measured leakage of 49.5 µA after 1 minute and 16.5 µA after 2 minutes at 20°C under rated voltage.
• Reliability & Lifetime — Endurance rated for 2000 hours at 105°C when operated at rated voltage.
• Package & Mounting — Radial lead, can-style package with case dimension φ10 mm × 16 mm, lead spacing 2.0 mm (±0.5 mm); packaged bulk / bag packing without terminal forming.
• AEC-Q200 Rating — Listed with an AEC-Q200 rating, enabling designs that require recognized component qualification.

Typical Applications

• High‑grade Audio Amplifiers — Bulk capacitance and low tan δ provide stable filtering and power decoupling for audio amplifier rails.
• Audio Preamplifiers and Signal Chains — Compact radial form factor and controlled loss angle make it suitable for power and coupling roles in high‑quality audio equipment.
• Audio Power Supplies — 50 V rating, ripple current capability and wide temperature range support smoothing and decoupling in audio power-supply modules.

Unique Advantages

• Audio-focused electrical performance — Low tan δ (0.14 at 120 Hz) and controlled leakage support cleaner power delivery and reduced noise contribution in audio systems.
• Thermal robustness — −55°C to +105°C operating range and 2000-hour endurance at 105°C deliver predictable behavior across harsh temperature conditions.
• Compact radial can — φ10 × 16 mm package with narrow lead spacing provides space-saving placement on through-hole PCBs without sacrificing capacitance performance.
• Frequency-aware ripple handling — Specified ripple currents at both 120 Hz and 10 kHz address low- and high-frequency ripple stresses common in audio power stages.
• Automotive-grade qualification — AEC-Q200 listing supports use in applications requiring qualified components (per manufacturer’s rating).
• Predictable leakage behavior — Quantified leakage values after 1 and 2 minutes at 20°C aid design verification and bias expectations.
