UKL2A1R5KDD

The UKL2A1R5KDD is a low-leakage aluminum electrolytic capacitor in a compact radial-lead can, offering 1.5 µF capacitance at a 100 V rating with ±10% tolerance. It is designed for applications where low leakage and a small footprint are important, with specifications and packaging aimed at audio and related electronics.

Key attributes include very low leakage current (0.3 µA), defined ripple current ratings across low and high frequency (23 mA at 120 Hz, 46 mA at 10 kHz), and an operating temperature range of −40 °C to +85 °C. The part is supplied in bulk or bag packing and is RoHS compliant.

Key Features

• Capacitance & Tolerance — 1.5 µF nominal capacitance with ±10% tolerance (K) at 120 Hz, 20 °C.
• Rated Voltage — 100 V DC rating for higher-voltage circuit use.
• Low Leakage Current — Specified leakage current of 0.3 µA, supporting stable bias conditions and minimal DC drift over time.
• Ripple Current Ratings — Low-frequency ripple current 23 mA at 120 Hz and high-frequency ripple current 46 mA at 10 kHz, enabling defined AC handling across common audio frequencies.
• Endurance — Life rating of 2000 hours at 85 °C with the rated voltage applied, per component specifications.
• Temperature Range — Specified operating range from −40 °C to +85 °C.
• Package & Size — Radial lead can, physical size φ5 × 11 mm (diameter × length) with lead spacing 2.0 mm (±0.5 mm).
• Polarization — Polarized electrolytic capacitor for DC applications.
• Compliance & Packaging — RoHS compliant; available in bulk (no terminal forming) and bag packing.
• Lifecycle Status — End Of Life status; check current availability and inventory for project planning.

Typical Applications

• Audio — General audio circuits — Suited to audio equipment where a low-leakage, small-form-factor capacitor is needed at elevated voltage ratings.
• Audio — Power supply decoupling in audio modules — Defined ripple current specifications at 120 Hz and 10 kHz support decoupling roles in audio power rails.
• Audio — Signal biasing and coupling — Low leakage current helps maintain stable bias conditions in sensitive audio signal paths.

Unique Advantages

• Very low leakage current: 0.3 µA leakage supports stable DC bias and reduces unwanted drift in precision audio circuits.
• High voltage capability in a compact can: 100 V rating in a φ5 × 11 mm package enables higher-voltage designs without a large footprint.
• Frequency-aware ripple handling: Specified ripple currents at both 120 Hz and 10 kHz provide predictable performance across low and high audio-related frequencies.
• Defined endurance at elevated temperature: 2000 hours at 85 °C under rated voltage gives a clear reliability expectation for thermal environments within the specified range.
• RoHS compliant and straightforward mounting: Radial-lead can with 2 mm lead spacing simplifies through-hole assembly and is compatible with standard wave or hand-soldering practices.
