THICK FILM RESISTOR NETWORKS (RA)
 
Features
 
  • Formed from metal glaze elements screened on ceramic substrates with strong clip construction terminals.

  • Small in size with high precise, single line, packaging.

  • Able to meet the need for increasing the density of circuit assembling.

  • Extremely stable, accurate, and reliable.
