Applications
The ESMQ451VSN471MA40S is designed for bulk energy storage and ripple filtering on the DC bus of industrial variable-frequency drives, servo amplifiers, and three-phase UPS systems operating at 400V AC input. Its 450V 470µF rating handles high ripple currents in the intermediate DC link stage of AC-DC power converters. The radial 35mm×40mm can fits standard snap-in or lead-through PCB footprints common in motor drive chassis.

Frequently Asked Questions
What voltage and capacitance does ESMQ451VSN471MA40S offer for industrial inverter DC bus filtering?
The ESMQ451VSN471MA40S is rated at 450V with 470µF capacitance, making it suitable for the DC bus of 3-phase inverters supplied from 400V AC mains. A pair of these capacitors in parallel delivers 940µF at 450V, providing adequate hold-up energy for short-duration mains dips in servo and VFD applications.
How large is the ESMQ451VSN471MA40S can, and what PCB mounting style does it use?
The ESMQ451VSN471MA40S uses a radial through-hole can measuring 35 mm in diameter and 40 mm in height, with standard lead spacing for PCB insertion. This form factor fits the IEC 60384-4 standard snap-in footprint used across most industrial power supply and inverter PCB platforms, simplifying design reuse.
What is the leakage current specification and how does it affect standby power in an always-on UPS design?
The ESMQ451VSN471MA40S specifies a maximum leakage current of 1.38mA at 450V. In a standby UPS with two capacitors in parallel, total leakage is under 2.76mA, contributing roughly 1.24W of standby dissipation at full rated voltage — a negligible fraction of the UPS idle power budget in multi-kilowatt systems.
Can ESMQ451VSN471MA40S replace a 400V-rated capacitor if only 400V DC bus voltage is used?
Yes, operating the ESMQ451VSN471MA40S at 400V — 50V below its 450V rating — extends capacitor life substantially, as aluminum electrolytic lifetime roughly doubles with every 10°C reduction in hotspot temperature or proportional voltage derating. The 50V headroom also improves reliability margin during transient overvoltage events common in regenerative motor drives.
