Notes

  1. C: Center gap O: Off center gap
  2. Breakdown voltage specifications are based on Pull-In sensitivity of 25 AT or higher. Contact ALEPH for information for switches with less than 25 AT sensitivity. HYR4000, HYR5000, HYR9000 Series are specified on basis of the lowest AT Pull-In sensitivity range.
  3. Ruthenium Oxide over Rhodium.
