Frequently Asked Questions
What is the capacitance value and package diameter of the ECA1HM471, and in what circuit roles does it excel?
The ECA1HM471 provides 470 µF capacitance in a 10 mm diameter radial leaded package. This combination suits bulk energy storage roles such as switching power supply output filtering, motor drive DC link capacitance, and hold-up capacitance in systems that must sustain voltage during 10 ms to 50 ms power interruptions.
How does the 0.235 mA leakage current of the ECA1HM471 affect circuit design in low-power standby applications?
At 0.235 mA leakage, the ECA1HM471 would consume approximately 0.235 mA continuously from the supply rail, totaling about 5.6 mW at a 24 V rail. For low-power standby circuits where total idle consumption is in the single-digit milliampere range, this leakage represents a meaningful fraction and designers should consider lower-leakage film capacitors or smaller electrolytic values in those stages.
What lead time should procurement expect for the ECA1HM471 and is it suitable for a long production program?
The ECA1HM471 carries a factory lead time of approximately 28 weeks and a YTEOL rating of 7 years. Production teams building designs with multi-year lifecycles should establish safety stock or blanket purchase orders well in advance, as the 28-week lead time reflects typical aluminum electrolytic manufacturing cycles at Panasonic's facilities.
