Key Features

  • 220µF capacitance at 25V DC rating with only 0.055mA leakage current for efficient energy storage and filtering in low-power SMD applications
  • 10mm height surface-mount aluminum wet electrolytic construction with JESD-609 e6 compliance for halogen-free and lead-free assembly processes
  • RoHS compliant and REACH certified Nippon Chemi-Con EMVE series with aluminum wet dielectric for high ripple current capability in power supply filtering

Applications

The EMVE250ADA221MHA0G is used in switch-mode power supply output filtering, where its 220µF capacitance at 25V smooths ripple voltage in DC-DC converters and AC-DC adapters operating at 12V to 24V output rails. Its surface-mount form factor and 10mm height suit mid-profile SMD designs in industrial equipment and telecommunications power modules. The low leakage of 0.055mA also makes it suitable for battery-backed hold-up circuits in portable medical devices and energy harvesting systems.

Frequently Asked Questions

What ripple current capability does EMVE250ADA221MHA0G offer for switch-mode power supply filtering at 220µF and 25V?

Nippon Chemi-Con EMVE series aluminum wet electrolytic capacitors at 220µF 25V are typically rated for ripple current of 300mA to 500mA at 100Hz and 105°C, depending on the case size. The EMVE250ADA221MHA0G with 10mm height SMD package handles ripple currents in the lower range due to its compact form factor. For high-ripple applications above 500mA at 25V, parallel placement of two EMVE250ADA221MHA0G units doubles the effective ripple handling to approximately 600mA to 1A.

Why is the 0.055mA leakage current of EMVE250ADA221MHA0G important for battery-powered circuit designs?

A leakage current of 0.055mA in EMVE250ADA221MHA0G means this 220µF 25V capacitor draws only 55 microamps continuously, which translates to approximately 1.3mAh per day of wasted battery charge. In a 1000mAh lithium cell, this leakage alone would reduce standby battery life by less than 0.2% per day, making it acceptable for IoT devices with months-long sleep cycles. This low leakage figure is critical for selecting hold-up capacitors in energy harvesting and long-life battery applications.

How does the EMVE250ADA221MHA0G compare to a ceramic 220µF capacitor for bulk output filtering in a 24V industrial supply?

At 220µF and 25V, aluminum wet electrolytic EMVE250ADA221MHA0G costs significantly less per unit than a ceramic capacitor of equivalent capacitance and voltage rating. Ceramic 220µF capacitors at 25V require multiple X5R or X7R MLCC components in parallel since individual MLCCs rarely exceed 100µF at 25V in standard SMD packages below 2220 size. The EMVE aluminum electrolytic also maintains its full 220µF nominal capacitance under DC bias, while ceramic capacitors lose 30% to 60% capacitance at 25V DC due to dielectric nonlinearity.

For a 5V to 25V bus converter in telecommunications, what ESR level does EMVE250ADA221MHA0G exhibit at 100kHz?

Nippon Chemi-Con EMVE series aluminum wet electrolytic capacitors in the 220µF 25V range typically exhibit ESR values of 0.5Ω to 1.5Ω at 100kHz at room temperature, depending on case dimensions. The 10mm height SMD package of EMVE250ADA221MHA0G places it in the moderate ESR category, suitable for output filtering in converters switching below 200kHz. For converters switching above 500kHz requiring ESR below 0.1Ω, a low-ESR polymer or solid aluminum electrolytic alternative would be more appropriate.
