Frequently Asked Questions
What are the capacitance, voltage, and tolerance ratings of the EEE-HA1H4R7R?
The EEE-HA1H4R7R is a 4.7 µF aluminum electrolytic capacitor rated at 50 V with ±20% capacitance tolerance. It is designed for SMD surface mount assembly and is supplied in full reels, making it suitable for automated placement in high-volume power supply and filtering applications across standard operating temperature ranges.
How does the EEE-HA1H4R7R perform in switch-mode power supply output filtering compared to ceramic alternatives?
The EEE-HA1H4R7R provides 4.7 µF electrolytic bulk capacitance at 50 V in an SMD package, which gives higher capacitance density per unit cost compared to ceramic MLCCs at the same voltage rating. In SMPS output filtering, its relatively higher ESR acts as a damping element, but for low-ripple designs it is often paralleled with a 100 nF ceramic capacitor to cover high-frequency noise above 1 MHz.
In which SMD assembly environments is the EEE-HA1H4R7R's full reel packaging most beneficial?
The full reel packaging of the EEE-HA1H4R7R is most beneficial in high-volume automated SMD pick-and-place lines where continuous feeding from a tape reel minimizes machine downtime and changeover. This is particularly useful in consumer electronics, LED lighting driver boards, and industrial control power supplies where 4.7 µF at 50 V electrolytic capacitors are placed in large quantities across 50 V power rails.
