What are the key features of EKMR451VSN471MR45S?

470 µF capacitance at 450 V rating, suitable for high-voltage bulk energy storage in power supply designs
Snap-in through-hole mounting provides mechanical stability in demanding vibration environments compared to axial or radial leads
30 mm diameter compact body enables high energy density in power factor correction and DC bus filtering circuits
RoHS-compliant (JESD-609 e3 coded) aluminum electrolytic construction with low leakage current of 1.38 mA

What is EKMR451VSN471MR45S used for?

The EKMR451VSN471MR45S is used in high-voltage DC bus filtering, power factor correction (PFC) stages, and bulk energy storage in industrial power supplies and motor drives rated up to 450 V. Its 470 µF capacitance handles large ripple currents in switch-mode power supply (SMPS) designs operating from rectified AC mains. The snap-in package is well suited for chassis-mounted or panel-mount power converters where mechanical stability under vibration is required.

Frequently Asked Questions

What is the voltage and capacitance rating of the EKMR451VSN471MR45S, and what circuit stage does this suit?

The EKMR451VSN471MR45S is rated at 450 V with 470 µF capacitance and 20% tolerance. This combination is suited for high-voltage DC bus filtering following a bridge rectifier in industrial SMPS designs connected to 230 V or 277 V AC mains, where the rectified DC bus can reach 320 V to 400 V under normal load conditions.

How does the snap-in mounting of EKMR451VSN471MR45S benefit power supply assembly compared to radial-lead capacitors?

The snap-in terminals of the EKMR451VSN471MR45S lock into the PCB or chassis bracket before soldering, holding the 30 mm diameter, physically heavy capacitor securely in place during wave soldering or reflow. This prevents movement that can cause solder joint stress in high-vibration environments such as industrial drives, where vibration levels can exceed 2 G at frequencies up to 100 Hz.

What is the leakage current of the EKMR451VSN471MR45S at rated voltage, and why does it matter in energy storage applications?

The EKMR451VSN471MR45S has a specified leakage current of approximately 1.38 mA at rated 450 V. In long-term energy hold-up or standby power applications, this leakage current represents a continuous power loss of about 0.62 W, which engineers must account for in thermal design and efficiency calculations for the power supply stage.

When should engineers consider EKMR451VSN471MR45S instead of a film capacitor for high-voltage bulk storage?

The EKMR451VSN471MR45S is preferred over film capacitors when 470 µF at 450 V is needed in a compact 30 mm diameter snap-in form factor, as an equivalent film capacitor would be several times larger and significantly more expensive. Aluminum electrolytic capacitors like this one offer a much higher capacitance-per-volume ratio at high voltages, making them the standard choice for DC bus bulk storage in power converters up to several kilowatts.
