UKL1C471KPD

The UKL1C471KPD is a radial-lead aluminum electrolytic capacitor designed for low-voltage, high-capacitance applications. It delivers 470 µF at a 16 V rating in a compact φ10×20 mm can suitable for through-hole board assemblies.

Engineered for audio and similar low-frequency applications, this part offers low leakage characteristics, defined ripple-current capability across low and high frequencies, and a 2000-hour endurance rating at 85°C for stable performance in temperature‑challenged environments.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance at a 16 V rated voltage with ±10% tolerance, providing predictable bulk capacitance for decoupling and smoothing.
• Low Leakage Current — Low leakage construction with a measured leakage current of 15.04 µA, supporting circuits that require minimal stand‑by drain.
• Loss Tangent (tan δ) — tan δ of 0.14 at 20°C, 120 Hz, enabling controlled ESR-related losses for audio and filtering tasks.
• Ripple Current Handling — Rated ripple current of 550 mA at 120 Hz (low frequency) and 825 mA at 10 kHz (high frequency), supporting both low- and high-frequency ripple demands.
• Reliability & Endurance — 2000 hours life at 85°C with restoration to 20°C meeting the specified endurance criteria for long-term operation.
• Operating Temperature Range — −40°C to +85°C, suitable for a wide range of ambient conditions encountered in consumer audio equipment.
• Package & Mounting — Radial-lead can, size φ10×20 mm with 5 mm lead spacing; available in bulk or bag packing for through-hole assembly workflows.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Audio — Bulk filtering, coupling and power supply smoothing in audio amplifiers and consumer audio equipment where low leakage and controlled ripple performance improve sound stability and noise floor.

Unique Advantages

• Low standby drain — The low leakage current (15.04 µA) minimizes unwanted drain in circuits that remain powered or idle for extended periods.
• Versatile ripple management — Defined ripple ratings at both 120 Hz and 10 kHz (550 mA and 825 mA respectively) let designers size the capacitor to handle expected AC ripple across common audio and power-supply frequencies.
• Compact, board-friendly form factor — φ10×20 mm radial can with 5 mm lead spacing fits tight through-hole layouts while delivering substantial capacitance for its size.
• Durability in elevated temperatures — 2000-hour endurance at 85°C gives predictable long-term behavior in thermally stressed designs.
• Predictable electrical performance — ±10% tolerance and a specified tan δ (0.14 at 20°C, 120 Hz) enable closer design matching for audio and filtering applications.
• Regulatory readiness — RoHS compliance supports designs targeting regions with restricted-substance requirements.
