UKL1E220MDD

The UKL1E220MDD is a radial-leaded aluminum electrolytic capacitor from Nichicon’s UKL series, designed for low leakage and reliable performance in compact through-hole applications. With a nominal capacitance of 22 µF at 25 V and a small φ5 × 11 mm can, it targets audio and other space-constrained circuits where stable DC bias and low loss are important.

This component combines low dissipation factor and measurable ripple-handling across low and high frequencies with a rated operating range of −40 °C to +85 °C and an endurance rating of 2000 hours at 85 °C, providing predictable behavior in typical embedded and consumer audio designs.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance rated at 25 V with tolerance −20% to +20% for predictable filtering and decoupling.
• Low Leakage — Low leakage current specified at 1.1 µA, supporting stable DC bias conditions in audio and signal circuits.
• Low Loss (tan δ) — tanδ (DF) = 0.08 measured at 20 °C, 120 Hz, minimizing dissipation in audio frequency ranges.
• Ripple Current Capability — Supports 100 mA at 120 Hz (low frequency) and 200 mA at 10 kHz (high frequency), enabling both power-supply smoothing and high-frequency decoupling.
• Reliability & Temperature — Endurance of 2000 hours at 85 °C and an operating temperature range of −40 °C to +85 °C for consistent field life in moderate-temperature applications.
• Form Factor & Mounting — Radial lead can (φ5 × 11 mm) with 2.0 mm lead spacing (±0.5 mm), available in bulk or bag packing for through-hole assembly.
• Regulatory — RoHS compliant, part of Nichicon’s low-leakage UKL series.

Typical Applications

• Audio circuits — Suited for coupling, decoupling and power-supply filtering in audio preamps, signal paths and small consumer audio devices where low leakage and low loss matter.
• Power-supply smoothing — Used in compact through-hole power rails to provide local energy storage and ripple suppression at both low and higher frequencies.
• General-purpose decoupling — Serves as a compact decoupling capacitor for control and analog boards requiring polarized electrolytic capacitance.

Unique Advantages

• Stable DC bias performance: Low leakage current (1.1 µA) helps preserve bias voltages and reduces drift in sensitive audio circuits.
• Low dissipation for audio fidelity: tanδ = 0.08 at 120 Hz limits energy loss in the audio band, supporting cleaner signal paths.
• Frequency-diverse ripple handling: Rated ripple current of 100 mA at 120 Hz and 200 mA at 10 kHz enables effective suppression across both low and high frequency noise components.
• Compact, through-hole form: Small φ5 × 11 mm can and radial leads provide a space-efficient option for PCB layouts that require through-hole components.
• Documented endurance: 2000 hours at 85 °C offers a clear reliability metric for lifetime planning in consumer and embedded designs.
• RoHS-compliant manufacturing: Aligns with environmental directives for lead-free production and assembly.
