25 A/85 A RT Chokes

Schaffner RT chokes provide common-mode EMI mitigation of 1-phase, DC, and 3-phase currents at 25 A and 85 A

Image of TE-Schaffner 25 A/85 A RT Chokes Schaffner 25 A and 85 A common-mode RT chokes provide excellent attenuation performance for 1-phase, DC, and 3-phase applications. They are typically used in power modules for electric vehicle infrastructure (EVI) up to 60 kW at 85 A. In these power modules, the chokes mitigate EMI on the grid side like an AC choke and also on the battery side like a DC choke. Other applications include heat pumps, drives, and industrial machinery, where high-current EMI mitigation on a PCB is necessary. This choke portfolio extension fills a gap in the series at 25 A and extends the current rating up to 85 A.

Benefits
  • Helps equipment to comply with EMC standards, as applications up to 60 kW can directly be filtered on the PCB
  • Horizontal and vertical integration options to adapt to existing space restrictions
  • Customers can choose from cost-effective ferrite and performance options with nanocrystalline cores to mitigate EMI for their case
  • Easy implementation into applications with UL requirements
  • Reliable mechanical fixation to the PCB with screw points in the base plate
  • Currents of 25 A and 85 A with natural convection; higher currents with forced-air cooling
  • Inductances of 0.2 mH to 17.3 mH with ferrite and nanocrystalline material
  • Reliable connection with through-hole terminals (THT)
Specifications
  • Designed per choke standard IEC 60938
  • Frequency: DC to 400 Hz
  • 300 VAC/450 VDC
  • Overvoltage category III
  • Nominal ambient temp: +60°C
  • Flammability rating: UL 94 V-0
Applications
  • Power modules of high-power DC charging stations
  • Battery electric storage systems (BESS)
  • Heat pumps
  • Drives
  • Industrial machinery
