B82791H2*N010 Series Ring Core Double Chokes

TDK Corporation has introduced the B82791H2*N010 series of very compact current compensated EPCOS power line ring core double chokes for very high frequencies. With a current rating from 1.5A to 4A and a nominal ambient temperature of +70 °C without derating, the new devices can offer inductance values of 14 µH to 100 µH at a 250V AC nominal voltage.

 

In an extremely compact 17.6 x 15.3 x 7.4 mm dimension, these new power chokes offer very high resonance frequencies and increased saturation capability, the device also eliminates the requirement of potting or any adhesives for allowing effective common-mode filtering at up to 300 MHZ and beyond. With a high stray inductance of up to 10%, these new ring core chokes are effective in suppressing the symmetric interference, hence they are suitable for applications such as compact switched power conversion applications, drives, and post-design EMC tuning on semi-finished PCB.

 

Features of B82791H2*N010 Series

  • Very compact design
  • Suitable for post-design EMC tuning on finished PCB
  • Very high resonance frequency and high saturation capability due to special core material and omission of potting
  • Effective common-mode filtering up to 300 MHz
  • Up to 10 percent stray inductance RoHS-compatible
