Frequently Asked Questions
What capacitance and voltage rating does the EEE-HA1H470P offer for SMD power supply filtering?
The EEE-HA1H470P provides 47 µF capacitance at a 50 V DC working voltage in a polarized SMD aluminum electrolytic package, giving a comfortable 30% to 40% voltage derating margin when used on 24 V to 35 V power rails. This combination of capacitance and voltage headroom suits output filtering on DC-DC converters, bulk decoupling on 24 V motor driver stages, and charge reservoir applications in switch-mode power supplies requiring ripple current handling across a wide operating temperature range.
How does the Panasonic HA series EEE-HA1H470P perform at elevated temperatures in industrial power circuits?
The EEE-HA1H470P HA series capacitor is rated for continuous operation at up to 105 °C, with a typical operating range starting from -40 °C, making it suitable for industrial control enclosures where ambient temperatures can reach 70 °C to 85 °C and internal hot-spot temperatures add another 20 °C from self-heating. At 105 °C rated voltage of 50 V, the capacitor maintains its 47 µF nominal capacitance within ±20% and ESR within datasheet limits, ensuring stable filtering performance over a design lifetime of 1,000 hours to 2,000 hours at maximum temperature.
In which SMD board layouts is the EEE-HA1H470P a practical replacement for a larger through-hole radial capacitor?
The EEE-HA1H470P is a direct SMD replacement for a 47 µF / 50 V radial electrolytic on boards converting to full SMT assembly, eliminating the separate wave soldering step or manual insertion required by through-hole components. On dense PCBs such as LED driver boards, power module daughter cards, and IoT gateway power sections, replacing a radial 6.3 mm x 11 mm capacitor with a surface-mount equivalent recovers 30 mm² to 50 mm² of board area and reduces the board layer routing complexity around through-hole annular rings.
What ripple current and ESR characteristics should engineers verify when using the EEE-HA1H470P in DC-DC converter output stages?
For the EEE-HA1H470P in a DC-DC converter output stage, designers should verify that the converter's rated output ripple current — typically 50 mA to 300 mA RMS at 100 kHz for a 5 W to 25 W converter — stays below the capacitor's rated ripple current specification, which for the HA SMD series at 105 °C is typically 150 mA to 400 mA depending on case size. Exceeding the ripple current rating causes internal heating that accelerates electrolyte evaporation, shortening capacitor life below the 1,000-hour minimum target and causing output voltage drift over the product's intended 5-year service life.
