UKL1C101KPD

The UKL1C101KPD is a Nichicon UKL series miniature aluminum electrolytic capacitor in a radial lead can. It delivers 100 µF capacitance at a 16 V rating and is part of a low-leakage current family optimized for compact power and signal conditioning tasks.

Designed for board-level implementations requiring polarized bulk capacitance, the UKL1C101KPD is suited to audio circuits and other low-voltage electronic designs that benefit from low leakage, modest ripple handling, and a compact φ8 × 11.5 mm package.

Key Features

• Capacitance & Voltage: 100 µF nominal capacitance with ±10% tolerance at a 16 V rated voltage, providing predictable bulk energy storage for low-voltage circuits.
• Low Leakage Current: Specified leakage current of 3.2 µA (measured condition), supporting applications where minimal self-discharge is important.
• Low Dissipation Factor: tanδ = 0.12 (20°C, 120 Hz), enabling efficient AC performance in filtering and coupling roles.
• Ripple Current Capability: Low-frequency ripple current 230 mA (120 Hz) and high-frequency ripple current 345 mA (10 kHz), supporting both power-supply smoothing and higher-frequency decoupling needs.
• Endurance: Rated life of 2000 hours at 85°C under rated voltage, providing defined long-term performance for thermal environments up to 85°C.
• Package & Mounting: Radial lead can, size φ8 × 11.5 mm with 3.5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for flexible assembly.
• Compliance: RoHS compliant, aligning with lead-free directive requirements.
• Lifecycle Status: End Of Life.

Typical Applications

• Audio circuitry: Bulk decoupling and power-supply filtering in audio preamplifiers and consumer audio modules where low leakage preserves bias and signal integrity.
• General low-voltage power supply: Smoothing and local energy storage in 16 V or lower DC rails for small electronic devices and control boards.
• Signal conditioning: Coupling/decoupling in analog front-ends where low dissipation factor and low leakage help maintain accurate signal paths.

Unique Advantages

• Compact radial-can form: φ8 × 11.5 mm package delivers significant capacitance in a small PCB footprint for space-constrained designs.
• Low self-discharge: 3.2 µA leakage current minimizes charge loss, aiding circuits that rely on stable bias or long idle periods.
• Balanced ripple capability: Specified ripple ratings at 120 Hz and 10 kHz allow designers to rely on the part for both mains-frequency smoothing and higher-frequency decoupling tasks.
• Defined thermal endurance: 2000 hours at 85°C under rated voltage provides a measurable reliability baseline for thermal design and lifetime planning.
• RoHS compliance: Meets lead-free directive requirements for environmentally conscious product lines.
• Radial-lead handling: 3.5 mm lead spacing and bulk/bag packaging options simplify through-hole assembly and manual or wave solder processes.
