UKL1E471MHD

The UKL1E471MHD is a radial-lead aluminum electrolytic capacitor designed for low leakage current applications. With a nominal capacitance of 470 µF and a 25 V rating, it targets audio and related electronic circuits that require stable biasing and decoupling.

This radial, can-style capacitor combines moderate ripple handling with a compact φ12.5×20 mm package and a -40℃ to 85℃ operating range, making it suitable for embedded and consumer audio designs where low leakage and reliable performance over time are important.

Key Features

• Capacitance & Tolerance — 470 µF nominal capacitance with ±20% tolerance for predictable energy storage and filtering.
• Rated Voltage & Polarization — 25 V rated, polarized design appropriate for DC bias applications.
• Low Leakage Current — Specified leakage current of 23.5 µA to minimize bias drift and standby losses in sensitive circuits.
• Ripple Handling — Low-frequency ripple current of 660 mA at 120 Hz and high-frequency ripple current of 990 mA at 10 kHz to support audio power and decoupling demands.
• Endurance & Temperature — Life rating of 2000 hours at 85℃ and an operating temperature range of -40℃ to 85℃ for stable performance in common environments.
• Package & Mounting — Radial lead, can-style package (φ12.5×20 mm) with 5 mm lead spacing (±0.5 mm), available in bulk or bag packing for board-level assembly.
• RoHS Compliance — Conforms to RoHS requirements for restricted substances.

Typical Applications

• Audio equipment — Provides low-leakage biasing and smoothing for audio power supplies and signal circuits where stable DC conditions are required.
• Power decoupling — Used for local energy storage and transient suppression in audio-related electronics that demand reliable ripple handling.
• Embedded consumer electronics — Fits compact boards needing a radial-lead capacitor with a small footprint (φ12.5×20 mm) and moderate ripple capability.

Unique Advantages

• Stable biasing with low leakage: 23.5 µA leakage current reduces DC drift and preserves circuit performance during idle conditions.
• Frequency-flexible ripple performance: Rated ripple currents of 660 mA (120 Hz) and 990 mA (10 kHz) support both low- and high-frequency noise rejection in audio paths.
• Compact radial can: φ12.5×20 mm package and 5 mm lead spacing simplify placement on densely populated PCBs while offering axial lead mounting convenience.
• Designed for sustained operation: 2000 hours at 85℃ endurance rating provides predictable lifetime behavior under elevated temperature stress.
• RoHS compliant: Meets regulatory restrictions for hazardous substances to support compliant product designs.
• Packaging options: Available in bulk or bag packing to accommodate prototyping and production workflows.
