UKL1J220MPD

The UKL1J220MPD is a Nichicon UKL series aluminum electrolytic capacitor designed for low leakage performance in through-hole radial-lead packages. This polarized 22 µF, 63 V capacitor delivers low dissipation (tanδ) and controlled ripple handling for audio and related electronic applications.

Built for compact assemblies, the part combines a φ8 × 11.5 mm can with 3.5 mm lead spacing and is specified for operation from −40 °C to +85 °C with a rated endurance of 2000 hours at 85 °C. It is RoHS compliant and supplied in bulk or bag packing.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance with tolerance −20% to +20% and a rated voltage of 63 V.
• Low Leakage Current — Specified leakage current: 2.772 µA (measured per product data) for minimal bias drain in sensitive circuits.
• Low Dissipation Factor — tanδ = 0.07 (measured at 20 °C, 120 Hz) to minimize loss in signal- and power-path applications.
• Ripple Current Capability — Low-frequency ripple current 115 mA (120 Hz) and high-frequency ripple current 230 mA (10 kHz) for smoothing and decoupling tasks.
• Mechanical & Mounting — Radial lead, polarized can package (φ8 × 11.5 mm), lead spacing 3.5 mm with 0.5 mm tolerance for straightforward through-hole assembly.
• Temperature & Endurance — Operating range −40 °C to +85 °C and qualified for 2000 hours at 85 °C.
• Compliance & Packing — RoHS compliant; available in Bulk (No Terminal Forming) or Bag packing.

Typical Applications

• Audio electronics — Suited for coupling, decoupling and smoothing roles in audio circuits where low leakage and low dissipation are important.
• Power filtering — Used in power rails of compact, through-hole designs to attenuate ripple at both low and high frequencies.
• General-purpose through-hole assemblies — Compact radial form factor supports space-constrained PCB layouts that require polarized electrolytic capacitors.

Unique Advantages

• Low leakage for stable biasing: The specified 2.772 µA leakage current helps preserve bias conditions in sensitive analog and audio circuits.
• Measurable loss performance: A tanδ of 0.07 at 120 Hz (20 °C) indicates reduced energy loss, benefiting signal fidelity and efficiency.
• Broad ripple handling: Dual ripple specifications (115 mA at 120 Hz and 230 mA at 10 kHz) provide design flexibility across frequency ranges.
• Compact radial package: φ8 × 11.5 mm can and 3.5 mm lead spacing deliver a small footprint for through-hole implementation.
• Specified endurance: Rated for 2000 hours at 85 °C, enabling predictable life-performance planning for thermal environments up to +85 °C.
• RoHS compliant: Conforms to RoHS requirements for regulatory compliance in many markets.
