UKL1E220KDD

The UKL1E220KDD is a radial-lead aluminum electrolytic capacitor offering 22 µF capacitance at a 25 V rating, optimized for low leakage and compact board-level placement (φ5 × 11 mm). It targets audio applications where stable decoupling, low leakage, and compact form factor are required.

This part features measured low leakage current (1.1 µA), defined ripple current capability (100 mA at 120 Hz, 200 mA at 10 kHz), and a rated endurance of 2000 hours at 85 °C. Note: Status — End Of Life.

Key Features

• Electrolytic Core — Aluminum electrolytic construction providing 22 µF capacitance with a ±10% tolerance at 120 Hz, 20 °C.
• Low Leakage Current — Typical leakage specified at 1.1 µA, supporting circuits that require minimal DC loss over time.
• Ripple Current Performance — Rated for 100 mA at 120 Hz and 200 mA at 10 kHz, supporting both low- and high-frequency decoupling in audio signal paths.
• Endurance and Temperature Range — Rated lifetime of 2000 hours at 85 °C with an operating temperature range of −40 °C to +85 °C.
• Compact Radial Package — Small footprint (φ5 × 11 mm) with 2.0 mm lead spacing (±0.5 mm), mounted via radial leads for through-hole assemblies.
• Regulatory Compliance — RoHS compliant as noted in product information.

Typical Applications

• Audio circuitry — Bulk decoupling and smoothing for preamplifiers and small signal stages where low leakage preserves bias points.
• Power filtering in audio equipment — Local rail filtering for audio amplifiers and analog front-ends, leveraging the part’s ripple current ratings.
• Portable audio devices — Compact through-hole mounting for devices that require reliable decoupling within a small PCB area and broad temperature tolerance.

Unique Advantages

• Measured low leakage: 1.1 µA leakage current minimizes DC loss and drift in bias-sensitive audio circuits.
• Balanced ripple capability: 100 mA at 120 Hz and 200 mA at 10 kHz make this part suitable for both power-line smoothing and higher-frequency decoupling tasks.
• Compact radial form: φ5 × 11 mm can free board space while providing through-hole mechanical retention for assemblies that require stronger physical mounting.
• Defined endurance: 2000 hours at 85 °C gives predictable life expectations under specified thermal stress.
• RoHS compliant: Meets environmental directive requirements for lead-free assembly environments.
