FAE Expert Insights
"The VM-47uF-35V is excellent for DC-DC converter output filtering. The low ESR significantly reduces output ripple compared to standard capacitors. I use this in 24V to 5V buck converters where low ripple is critical. The 105°C rating provides good margin for thermal performance."

Frequently Asked Questions
What makes VM series different from VF series?
VM series features lower ESR (0.8 Ohm vs 1.5 Ohm) and higher ripple current capability (0.28A vs 0.15A). The VM series is designed for high-frequency switching applications where low impedance is critical. VF series is suitable for general-purpose applications.
Choose VM series for high-frequency switching, VF series for general applications.
What is the maximum switching frequency for this capacitor?
The VM series is optimized for switching frequencies up to 500kHz. The low ESR makes it suitable for modern DC-DC converters operating at high frequencies. Above 500kHz, ceramic capacitors should be used in parallel.
Use for switching frequencies up to 500kHz. Add ceramic capacitors for higher frequencies.
