Key Features
- 47µF at 50V in a compact 6.3 mm diameter radial through-hole package enables reliable bulk energy storage and decoupling in tight board layouts
- NHG series aluminum electrolytic construction provides low leakage current (0.0235mA max) for stable bias filtering in low-power circuits
- RoHS-compliant, Pb-free radial capacitor compatible with standard lead-free soldering profiles for industrial and consumer electronics assembly
Applications
The ECA1HHG470 is widely used as a bulk decoupling and energy storage capacitor on 12V to 48V DC rails in switching power supply output filters, audio amplifier bias circuits, and motor control boards. Its 47µF at 50V NHG construction provides stable capacitance for smoothing rectified AC power in low-to-medium power supplies with output voltages up to 35V DC under ample derating. Consumer electronics, industrial sensors, and HVAC control boards also use this radial capacitor for hold-up energy storage on 24V and 48V bus segments.

Frequently Asked Questions
What is the maximum safe DC working voltage for the ECA1HHG470 when used in a 35V DC power supply output filter?
The ECA1HHG470 is rated at 50V DC, providing approximately 1.43× derating margin when used on a 35V DC rail. Standard engineering practice recommends derating aluminum electrolytic capacitors to 80% of rated voltage for long service life, which would set a practical limit of 40V DC for this capacitor. At 35V, the ECA1HHG470 operates well within both its rated 50V and the 80% derating guideline, ensuring reliable performance with low 0.0235mA leakage current over a service life typical of NHG-series parts.
How does the 6.3 mm diameter body of ECA1HHG470 compare to a larger 8 mm or 10 mm diameter 47µF 50V capacitor in a PCB footprint context?
The ECA1HHG470's 6.3 mm diameter body requires a PCB pad pitch of approximately 2.5 mm and a hole spacing matching the radial lead spacing, occupying roughly 31 mm² of board area. An 8 mm diameter alternative requires a 3.5 mm lead spacing and approximately 50 mm² footprint area, while a 10 mm body needs 5 mm pitch and about 79 mm². Choosing the 6.3 mm ECA1HHG470 saves up to 60% board area compared to 10 mm alternatives, which is significant when fitting multiple filter capacitors near a switching converter output stage.
For which audio amplifier bias or smoothing applications is a 47µF 50V aluminum electrolytic like ECA1HHG470 the correct choice over a film or ceramic capacitor?
In audio amplifier circuits, a 47µF 50V aluminum electrolytic like ECA1HHG470 is chosen for DC bias decoupling on power rails (typically 12V to 48V), coupling between amplifier stages where the AC signal must pass but DC offset must be blocked, and reservoir filtering after rectification. Film capacitors at 47µF would be physically large and expensive, while ceramic capacitors in this capacitance range lack sufficient voltage rating and exhibit piezoelectric microphonic noise. The NHG series' 0.0235mA leakage current keeps DC bias errors minimal in Class A or Class AB audio output stages.
