Frequently Asked Questions
What capacitance and voltage rating does EEE-HD1H4R7R provide, and for which power supply rail is it best suited?
EEE-HD1H4R7R is rated at 4.7 µF capacitance and 50 V maximum working voltage with ±20% tolerance. It is well-suited for output filtering on 5 V to 48 V power rails in DC-DC converters and for bulk decoupling on PCBs where a low-ESR aluminum electrolytic is acceptable at moderate frequencies up to 100 kHz.
What operating temperature range does EEE-HD1H4R7R support for industrial and automotive accessory designs?
Panasonic HD series aluminum electrolytic capacitors like EEE-HD1H4R7R operate across a temperature range of -40°C to 85°C, maintaining stable 4.7 µF capacitance within ±20% through the full range. This makes the part suitable for industrial control boards and automotive accessory circuits that experience thermal cycling from cold startup to under-hood temperatures.
How does the EEE-HD1H4R7R 4.7 µF SMD aluminum electrolytic compare to a ceramic MLCC for 50 V DC filtering?
At 50 V and 4.7 µF, EEE-HD1H4R7R aluminum electrolytic is significantly lower cost than an X5R or X7R ceramic MLCC of the same rating, since 50 V MLCCs at 4.7 µF require larger 1210 or 1812 case sizes. The electrolytic trades slightly higher ESR (typically 2 ohm to 5 ohm at 100 kHz) for a smaller BOM cost in non-RF power filtering applications.
What packaging quantity does EEE-HD1H4R7R come in, and does this affect minimum order volume for production?
EEE-HD1H4R7R is supplied as a full reel of 2000 pieces, optimized for continuous pick-and-place assembly without reel changes mid-run. For lower-volume prototyping requiring fewer than 2000 units, buyers should confirm cut-tape availability from distributors, since minimum order quantity for full reels is typically 1 reel (2000 pcs) at 50 V and 4.7 µF rating.
