Frequently Asked Questions
What are the rated capacitance and voltage for the EEE-1CA470WR, and which power rail voltages does it support?
The EEE-1CA470WR is rated at 47 µF capacitance and 16 V DC working voltage. It is suitable for filtering and decoupling rails up to 16 V, such as 3.3 V, 5 V, and 12 V supply lines common in embedded systems, consumer electronics, and industrial control boards where compact SMD electrolytic capacitors are required.
How does the SMD package of the EEE-1CA470WR compare to through-hole aluminum electrolytics in board assembly?
The EEE-1CA470WR in an SMD package enables fully automated pick-and-place and reflow solder assembly, reducing manufacturing time and cost compared to through-hole alternatives. The surface-mount footprint occupies less board height than through-hole capacitors, making it preferable for low-profile PCB designs in portable devices and compact power modules where 47 µF at 16 V is required.
In which switching converter topologies is the EEE-1CA470WR most effective as an output filter capacitor?
The EEE-1CA470WR is effective as an output filter capacitor in buck (step-down) and boost (step-up) DC-DC converter topologies operating at voltages up to 16 V. Its 47 µF capacitance provides adequate energy storage and ripple current absorption at switching frequencies from a few kHz up to hundreds of kHz, depending on the converter design.
Is the EEE-1CA470WR a suitable alternative to ceramic capacitors for bulk filtering at 47 µF?
Yes, the EEE-1CA470WR offers a cost-effective 47 µF bulk filtering solution compared to multi-layer ceramic capacitors (MLCC) of equivalent capacitance, which become expensive and physically large above 10 µF at 16 V. The aluminum electrolytic construction provides stable capacitance under DC bias, unlike MLCCs that can lose up to 80% capacitance under rated voltage, making the EEE-1CA470WR reliable for low-frequency bulk storage applications.
