UKA1E470MDD

The UKA1E470MDD is a Nichicon UKA-series aluminum electrolytic capacitor in a radial lead can, specified at 47 µF and 25 V. It is designed for use in audio and related electronic equipment where compact through-hole capacitors with defined ripple-handling and wide temperature capability are required.

Key value propositions include a wide operating temperature range (−55°C to 105°C), 2000 hours endurance at 105°C, measurable low leakage, and specified ripple current performance across low and high frequency bands.

Key Features

• Capacitance and Voltage — 47 µF rated capacitance with a 25 V rated voltage and ±20% tolerance (at 120 Hz, 20°C) for predictable bulk capacitance in power and audio circuits.
• Ripple Current Performance — Specified low-frequency ripple current of 83 mA at 120 Hz and high-frequency ripple current of 166 mA at 10 kHz for filtering and decoupling across audio-relevant frequencies.
• Low Leakage — Leakage current specified at 35.25 µA, supporting stable bias conditions in signal and power paths.
• Endurance and Temperature Range — Rated for 2000 hours at 105°C and an operating temperature range of −55°C to 105°C, enabling deployment in thermally demanding environments.
• Mechanical and Mounting — Radial lead (can) package with φ5 × 11 mm dimensions and 2 mm lead spacing for compact through-hole mounting and straightforward assembly.
• Qualification — AEC-Q200 rating is included for component-level stress qualification used in demanding electronic applications.
• Packaging — Supplied in bulk (no terminal forming) or bag packing to suit production and prototype usage.

Typical Applications

• High-grade audio equipment — Bulk and decoupling capacitor for power rails and filtering stages where stable capacitance and low leakage support audio performance.
• Power supply filtering — Smoothing and ripple suppression in small form-factor power supplies where the specified ripple current ratings are relevant.
• Embedded and through-hole electronics — Compact radial can footprint for designers who require reliable through-hole capacitors with a wide temperature range and defined endurance.

Unique Advantages

• Wide operating temperature range — −55°C to 105°C supports deployments across varied thermal environments without derating beyond specified limits.
• Long-duration endurance — 2000 hours at 105°C offers predictable aging behavior for designs requiring sustained high-temperature operation.
• Frequency-aware ripple handling — Separate ripple current specifications for 120 Hz and 10 kHz help designers size capacitors based on the dominant ripple frequency in their circuits.
• Compact radial can — φ5 × 11 mm package and 2 mm lead spacing deliver a small footprint for space-constrained PCB layouts while maintaining through-hole robustness.
• Low leakage — Specified leakage current of 35.25 µA reduces bias drift and leakage-related issues in sensitive circuits.
• Industry qualification — AEC-Q200 rating provides a baseline qualification status for use in designs that require component-level stress screening.
