UKL1A331MPD

The UKL1A331MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UKL series designed for low-voltage, compact applications. This polarized, standard-type capacitor delivers 330 µF capacitance at a 10 V rating in a φ10 × 12.5 mm can with 5 mm lead spacing.

Key value propositions include low leakage performance (6.6 µA specified), measurable ripple handling (400 mA at 120 Hz; 600 mA at 10 kHz), and an endurance rating of 2000 hours at 85°C. Note: Status is End Of Life.

Key Features

• Capacitance and Voltage — 330 µF capacitance with a 10 V rated voltage and ±20% tolerance, suitable for low-voltage circuit designs.
• Low Leakage Current — Specified leakage current of 6.6 µA (measurement conditions as provided), supporting low-standby and low-bias applications.
• Ripple Current Capability — Rated ripple current of 400 mA at 120 Hz and 600 mA at 10 kHz, enabling effective smoothing and decoupling in low-voltage power rails.
• Electrical Loss (tan δ) — Tan δ of 0.15 at 20°C, 120 Hz (measured at 10 V for this part), indicating controlled dissipation factor for the specified case size.
• Endurance and Temperature Range — Endurance of 2000 hours at 85°C and operating range from –40°C to +85°C for stable performance across typical ambient conditions.
• Compact Radial Package — φ10 × 12.5 mm can, radial lead mounting with 5 mm lead spacing (±0.5 mm), packaged bulk/bag for through-hole assembly.
• RoHS Compliant — Meets RoHS directive requirements as indicated in product data.

Typical Applications

• Audio equipment — Intended for audio applications where a compact, low-voltage electrolytic capacitor is required for power filtering or coupling.
• Compact low-voltage power rails — Suitable for smoothing and decoupling on 10 V-class regulator outputs and small consumer electronics power supplies.
• Through-hole PCB assemblies — Radial-lead package and 5 mm lead spacing make it a fit for standard through-hole placement in compact board layouts.

Unique Advantages

• Low leakage for reduced standby draw — The specified 6.6 µA leakage current helps minimize bias current in low-power circuits.
• Measured ripple performance — Rated ripple currents at both low (120 Hz) and high (10 kHz) frequencies provide designers with clear limits for thermal and lifetime budgeting.
• Small footprint — φ10 × 12.5 mm can offers a compact solution for space-constrained designs while retaining respectable capacitance.
• Proven endurance — 2000 hours at 85°C endurance rating supports predictable aging characteristics in typical operating environments.
• Industry compliance — RoHS compliance supports regulatory requirements for lead-free manufacturing.
