UKL2A330KPD

The UKL2A330KPD is a radial-lead aluminum electrolytic capacitor offering 33 µF capacitance at a 100 V rating in a compact φ10 × 16 mm can with 5 mm lead spacing. It is part of Nichicon’s UKL low-leakage-current series and is intended for audio applications that require low leakage, defined ripple handling, and long endurance at elevated temperature.

Key device characteristics include low leakage current (per UKL series specification), a 2000-hour endurance rating at 85°C with rated voltage applied, RoHS compliance, and bulk packaging. Note: the UKL series includes products that are scheduled to be discontinued and are not recommended for new designs.

Key Features

• Capacitance & Tolerance — 33 µF nominal with ±10% tolerance (K) at 120 Hz, 20°C.
• Voltage Rating — 100 V DC rated voltage for higher-voltage audio and related circuits.
• Low Leakage Current — Meets UKL series leakage specification (≤ 0.002 C V μA), measured after 2 minutes for case sizes φ10 × 16 or larger.
• Endurance — Rated for 2000 hours at 85°C with rated voltage applied; electrical characteristics meet specified limits after recovery to 20°C.
• Ripple Current Capability — Specified ripple current: 180 mA at 120 Hz and 360 mA at 10 kHz (85°C ratings as provided).
• Package & Dimensions — Radial lead can, φ10 × 16 mm (L), 5 mm lead spacing; compact 1.6 cm × 1.0 cm footprint (L × D).
• Operating Temperature — Specified for −40°C to +85°C operation.
• Polarized Construction — Polarized electrolytic capacitor for DC applications.
• Compliance & Marking — RoHS compliant; marked with white lettering on a black sleeve.

Typical Applications

• Audio circuits — Designed for audio circuitry where low leakage and a 100 V rating support coupling, decoupling, and power supply filtering in higher-voltage segments.

Unique Advantages

• Low leakage behavior — Leakage limited to the UKL series specification (≤ 0.002 C V μA), reducing bias drift in audio stages and DC-blocking applications.
• High-voltage capability — 100 V rating enables use in audio power rails and other higher-voltage circuits without series stacking.
• Long elevated-temperature life — 2000 hours at 85°C under rated voltage supports longer service in thermally stressed equipment.
• Defined ripple performance — Rated ripple currents of 180 mA (120 Hz) and 360 mA (10 kHz) give predictable thermal and filtering behavior at common frequencies.
• Compact radial can format — φ10 × 16 mm housing with 5 mm lead spacing simplifies board placement in dense layouts while retaining necessary capacitance and voltage rating.
• Regulatory compliance — RoHS compliant for use in regions requiring restricted substance adherence.

Why Choose UKL2A330KPD?

UKL2A330KPD combines a compact φ10 × 16 mm radial can with a 100 V rating, low-leakage performance and defined ripple-current capability to meet demanding audio and related DC applications. Its 2000-hour endurance at 85°C and RoHS compliance make it suitable for designs that require predictable behavior over time and regulatory conformity.

Because this part is provided in bulk packaging and follows Nichicon’s UKL low-leakage specification set, it is particularly useful for engineers and buyers maintaining or repairing existing audio designs that already specify the UKL series. Please note the series has products scheduled for discontinuation and is not recommended for new designs.
