UKL2A100KPD

The UKL2A100KPD is an aluminum electrolytic capacitor from Nichicon’s UKL series, packaged in a radial can (φ8 × 11.5 mm) with radial leads and 3.5 mm lead spacing. It delivers 10 µF capacitance at a 100 V rating with low leakage characteristics tailored for audio applications and other designs that require compact, polarized bulk capacitance.

Key value propositions include low leakage current per the UKL series specification, a compact radial footprint for through‑hole assemblies, RoHS compliance, and a rated operational range of –40 °C to +85 °C with a 2000‑hour endurance at 85 °C.

Key Features

• Capacitance & Voltage — 10 µF capacitance with a 100 V rated voltage and ±10% tolerance (K), suitable where higher voltage polarized capacitance is required.
• Low Leakage Current — UKL series low leakage specification: leakage current not more than 0.002CV (µA) after 1 minute application of rated voltage at 20 °C for case sizes φ10×12.5 mm or smaller.
• Compact Radial Can — φ8 mm diameter × 11.5 mm length (L: 1.15 cm × D: 0.8 cm) with radial lead mounting and 3.5 mm lead spacing for through‑hole PCB layouts.
• Ripple Current Capability — Rated ripple current values provided for low and high frequency: 90 mA at 120 Hz and 180 mA at 10 kHz.
• Operating Temperature & Endurance — Specified operating range of –40 °C to +85 °C and a lifetime/endurance rating of 2000 hours at 85 °C under rated voltage.
• Polarized Bulk Package — Radial, can style with standard polarity marking, supplied in bulk (no terminal forming) / bag packing for volume assembly.
• Regulatory — RoHS compliant.

Typical Applications

• Audio equipment — Intended for audio applications where a 10 µF, 100 V polarized capacitor with low leakage is specified.
• Through‑hole power modules — Compact radial footprint and 100 V rating suit designs requiring higher voltage bulk capacitance in through‑hole assemblies.
• General electronic equipment — Applicable where RoHS compliance, low leakage characteristics, and the specified temperature/lifetime profile are required.

Unique Advantages

• Low leakage by series specification — The UKL series leakage limit (≤ 0.002CV µA after 1 minute at 20 °C for small case sizes) reduces DC bias loss and leakage‑related drift in sensitive circuits.
• High voltage in a small package — 100 V rating in a φ8 × 11.5 mm radial can provides high working voltage without a large PCB footprint.
• Compact radial lead form factor — 3.5 mm lead spacing and standard radial can make it straightforward to integrate into through‑hole layouts and legacy designs.
• Defined ripple performance — Specified ripple current at 120 Hz and 10 kHz supports predictable thermal and lifetime planning across frequencies.
• Temperature endurance data — 2000 hours at 85 °C endurance rating enables lifetime projections for designs operating within the specified temperature range.
• RoHS compliant — Meets RoHS directive requirements for restricted substances.
