UKL1C331KPD

The UKL1C331KPD is a Nichicon UKL series aluminum electrolytic capacitor optimized for low leakage performance in a compact radial-lead can. It delivers 330 µF at 16 V with ±10% tolerance and is intended for audio applications where low leakage and reliable ripple handling are important.

Key electrical and mechanical attributes include a low dissipation factor (tanδ ≈ 0.14 at 20°C, 120 Hz), radial lead mounting with 5 mm lead spacing, and a small φ10 × 16 mm can size. The part is RoHS compliant. Note: this part is End Of Life and the UKL series is scheduled for discontinuation; it is not recommended for new designs.

Key Features

• Capacitance & Voltage: 330 µF rated capacitance at 16 V with ±10% tolerance, suitable where moderate energy storage is required in a small footprint.
• Low Leakage Series (UKL): Designed as part of Nichicon’s low leakage-current UKL series for applications that benefit from reduced self-discharge.
• Low Dissipation Factor: tanδ ≈ 0.14 measured at 20°C, 120 Hz, supporting efficient performance in AC and ripple environments.
• Ripple Current Capability: Handles 420 mA at 120 Hz (low frequency) and 630 mA at 10 kHz (high frequency), enabling effective smoothing and decoupling under AC ripple stress.
• Leakage Current: Low leakage current specified (10.56 µA for this part), supporting circuits sensitive to leakage and bias stability.
• Endurance & Temperature Range: Rated for 2000 hours at 85°C and an operating range of –40°C to 85°C for stable performance across typical consumer operating conditions.
• Compact Radial Package: φ10 × 16 mm aluminum can with radial leads and 5 mm lead spacing (±0.5 mm), offered in bulk or bag packing for manual or through-hole assembly.
• Compliance: RoHS compliant, consistent with current environmental directives.

Typical Applications

• Audio equipment — Suited for audio circuitry where low leakage and reliable ripple handling are needed for power supply smoothing and filter stages.
• Audio amplifiers and preamps — Compact radial can form factor fits space-constrained boards in consumer and professional audio devices.
• Audio signal and bias circuits — Low leakage supports circuits that require maintained bias and minimal self-discharge.

Unique Advantages

• Low leakage performance: Minimizes self-discharge and preserves bias conditions, advantageous for sensitive audio stages and long idle times.
• Balanced ripple capability: Specified ripple ratings at both low and high frequencies (420 mA at 120 Hz, 630 mA at 10 kHz) support effective smoothing across a range of switching and linear supply conditions.
• Compact radial footprint: φ10 × 16 mm can with 5 mm lead spacing delivers a high-capacitance solution in a small through-hole package for board-space-limited designs.
• Long endurance at rated conditions: 2000 hours at 85°C provides predictable life characteristics for stable performance in consumer audio applications.
• RoHS compliance: Meets environmental directive requirements for reduced hazardous substances.
