What are the key features of EEE-HD1E4R7AR?
- 4.7 µF capacitance at 25 V with ±20% tolerance in an SMD package for space-saving surface-mount PCB assembly on high-density boards
- Aluminum electrolytic construction delivers cost-effective bulk capacitance for decoupling and power rail filtering compared to equivalent ceramic alternatives at higher voltages
- 25 V working voltage provides a comfortable safety margin on 12 V, 15 V, and 20 V power rails common in consumer electronics and industrial control applications
- SMD construction with tape-and-reel packaging supports automated pick-and-place assembly in high-volume production for consumer and industrial electronics
What is EEE-HD1E4R7AR used for?
EEE-HD1E4R7AR is used as a decoupling and bypass capacitor on 5 V, 12 V, and 20 V supply rails in smartphones, tablets, laptop power management circuits, and audio amplifier boards where small SMD aluminum electrolytics at 25 V provide cost-effective bulk capacitance. It also serves as an output filter capacitor in low-power DC-DC converters and linear regulators, smoothing ripple on rails below 20 V. Industrial designers use it in sensor signal conditioning circuits and motor-drive auxiliary power supplies that require compact 4.7 µF SMD capacitors with adequate voltage headroom.

Frequently Asked Questions
What are the capacitance and voltage ratings of EEE-HD1E4R7AR, and on which power rails can it be safely used?
EEE-HD1E4R7AR is rated at 4.7 µF capacitance and 25 V working voltage with ±20% tolerance, meaning its capacitance may range from 3.76 µF to 5.64 µF. It can be safely used on power rails up to 20 V with the standard 20% voltage derating rule applied in most engineering guidelines, covering 5 V, 12 V, and 15 V rails common in consumer electronics and industrial PCBs.
How does EEE-HD1E4R7AR perform as an output filter capacitor for a 5 V DC-DC converter?
As an output filter capacitor on a 5 V switching regulator, EEE-HD1E4R7AR provides 4.7 µF of bulk capacitance to reduce output voltage ripple. For a converter switching at 500 kHz with a 200 mA load step, this capacitance limits the transient voltage undershoot to approximately 10 mV to 30 mV depending on the converter's feedback loop bandwidth, making it suitable for low-current digital logic supply filtering where ripple requirements are under 50 mV.
Why choose an aluminum electrolytic like EEE-HD1E4R7AR instead of a ceramic MLCC at 4.7 µF, 25 V?
A ceramic MLCC at 4.7 µF rated for 25 V typically requires X5R or X7R dielectric in an 0805 or 1206 case, and suffers from up to 80% capacitance loss under DC bias at 20 V, effectively delivering only 0.9 µF to 2 µF in-circuit. EEE-HD1E4R7AR maintains its 4.7 µF aluminum electrolytic capacitance with far less DC-bias derating, making it a cost-effective alternative for bulk decoupling where the full 4.7 µF is needed across the operating voltage range.
How does the SMD package of EEE-HD1E4R7AR simplify manufacturing on high-volume consumer electronics boards?
EEE-HD1E4R7AR's surface-mount form factor and tape-and-reel packaging allow it to be placed by standard pick-and-place machines at rates exceeding 20,000 placements per hour, eliminating the manual insertion or axial lead-forming steps required for through-hole radial electrolytic capacitors of similar 4.7 µF, 25 V ratings. This reduces assembly labor cost and improves placement accuracy on PCBs with a component density above 50 parts per cm².
