The device operates across –40℃ to 85℃ and is supplied in a φ8 × 11.5L can with 3.5 mm lead spacing. Status: End Of Life.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a 50 V rated voltage and ±10% tolerance for predictable energy storage and filtering.
• Low Leakage Current — Specified leakage current of 3.3 µA supports applications where minimizing standby or bias leakage is important.
• Ripple Performance — Low-frequency ripple current rating of 165 mA at 120 Hz and high-frequency ripple current of 330 mA at 10 kHz, enabling reliable smoothing across a range of ripple spectra.
• Package & Mounting — Radial lead, can-style package (φ8 × 11.5L) with 3.5 mm lead spacing (±0.5 mm) for straightforward through-hole mounting and mechanical stability.
• Temperature & Endurance — Operating temperature range from –40℃ to 85℃ and an endurance rating of 2000 hours at 85℃ for predictable lifetime behavior under rated conditions.
• RoHS Compliant — Manufactured to meet RoHS requirements as indicated in product documentation.

Typical Applications

• Audio electronics — Low leakage and defined ripple ratings make the UKL1H330KPD suitable for audio power supply filtering and decoupling where signal integrity matters.
• Power smoothing — 33 µF capacitance and specified ripple currents support bulk smoothing and local decoupling in low- to mid-power boards.
• General-purpose electronic equipment — Compact radial can and broad temperature range address common requirements for industrial and consumer circuit designs.

Unique Advantages

• Precise tolerance: ±10% capacitance tolerance provides tighter control for designs that require predictable filter characteristics.
• Low standby loss: 3.3 µA leakage current reduces bias and standby current impact in sensitive circuits.
• Frequency-aware ripple ratings: Separate low-frequency (165 mA @120 Hz) and high-frequency (330 mA @10 kHz) ripple specifications let designers assess performance across common ripple bands.
• Compact radial footprint: φ8 × 11.5L can with 3.5 mm lead spacing delivers a small physical profile while retaining axial stability for through-hole assembly.
• Robust temperature and life specification: –40℃ to 85℃ operating range and 2000 hours at 85℃ endurance support predictable long-term performance under rated conditions.
• Regulatory compliance: RoHS status aligns with common environmental requirements for commercial electronics.
