Frequently Asked Questions
What ESR value does the EMVH500ARA221MKE0S exhibit and at which frequency is it specified?
The EMVH500ARA221MKE0S has a specified ESR of 230 mΩ measured at 100 kHz, which determines its effectiveness in attenuating switching ripple from DC-DC converters operating at typical frequencies of 100 kHz to 500 kHz in industrial power supply designs.
What capacitance and voltage rating make the EMVH500ARA221MKE0S suitable for 24 V bus filter stages?
With 220 µF capacitance and a 50 V working voltage rating, the EMVH500ARA221MKE0S provides sufficient voltage headroom and bulk energy storage for 24 V and 36 V bus decoupling, allowing designers to maintain stability with a 40% voltage derating margin from the rated 50 V.
What are the physical dimensions of the EMVH500ARA221MKE0S SMD can?
The EMVH500ARA221MKE0S measures 12.5 mm in diameter and 13.5 mm in height, with surface-mount terminations suitable for automated placement. This form factor is compatible with standard SMD aluminum electrolytic footprint land patterns on industrial and telecom power boards.
When should the EMVH500ARA221MKE0S be selected over a polymer aluminum capacitor for the same 220 µF 50 V role?
Wet aluminum electrolytic capacitors like the EMVH500ARA221MKE0S are preferred when 220 µF at 50 V is needed at lower cost than solid polymer alternatives, and the application operates below 85°C ambient where the longer lifespan advantage of polymer types at elevated temperatures is not critical.
