UKL1J220KPD

The UKL1J220KPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UKL series. It offers 22 µF capacitance at a 63 V rating in a compact φ8 × 11.5 mm can, optimized for through-hole assemblies.

Designed for audio applications, this standard-type capacitor delivers low leakage, low loss (tanδ), and defined ripple-handling capability, making it suitable for coupling, decoupling and power-smoothing roles in audio circuitry that require modest ripple currents and stable performance across –40°C to 85°C.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance with a rated voltage of 63 V and tolerance of -10%~10%.
• Low Leakage Current — Specified leakage current of 2.772 µA (measured conditions per product data), supporting applications where retained charge and low quiescent leakage are important.
• Low Dissipation Factor (tanδ) — tanδ = 0.07 at 20°C, 120 Hz, indicating lower AC loss for improved audio fidelity and efficiency in signal paths.
• Ripple Handling — Rated low-frequency ripple current of 115 mA at 120 Hz and high-frequency ripple current of 230 mA at 10 kHz, suitable for typical audio supply filtering and decoupling tasks.
• Reliability — Endurance rated for 2000 hours at 85°C with rated voltage applied, providing defined life performance for sustained operating conditions.
• Package & Mounting — Radial lead (polarized) can package, size φ8 × 11.5 mm, lead spacing 3.5 mm (±0.5 mm), available in bulk (no terminal forming) or bag packing for prototype and production use.
• Temperature Range — Operating range from –40°C to 85°C, aligning with common audio and general-purpose electronics environments.
• RoHS Compliant — Meets RoHS requirements per product documentation.

Typical Applications

• Audio signal coupling — Low leakage and low tanδ characteristics make the UKL1J220KPD suitable for coupling stages where preserving signal integrity is important.
• Audio power supply smoothing — Ripple current ratings support use in local supply decoupling and smoothing for audio amplifiers and preamps.
• Input/output audio stages — Compact radial lead package fits through-hole audio boards for input/output coupling and DC blocking.

Unique Advantages

• Measurable low leakage — The specified 2.772 µA leakage current provides predictable behavior in circuits where leakage impacts bias or retention.
• Low dissipation for audio fidelity — tanδ = 0.07 at 120 Hz helps minimize AC loss in signal paths, contributing to clearer audio performance.
• Compact, through-hole form factor — φ8 × 11.5 mm can and 3.5 mm lead spacing enable space-efficient PCB layouts and straightforward manual or wave solder assembly.
• Defined ripple capability — Separate low- and high-frequency ripple ratings (115 mA @120 Hz, 230 mA @10 kHz) give clear guidance for placement in supply-filtering topologies.
• Documented endurance — 2000 hours at 85°C provides a quantified reliability basis for design planning and lifecycle assessment.
• RoHS compliance — Conforms to RoHS requirements as stated in the product documentation.
