  1. When ordering, please specify a packaging code: e.g. JA4220-ALC
  2. Inductance measured at 1 MHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4192 or equivalent.
  3. DCR measured on a micro-ohmmeter at 25°C. For other operating temperatures, use this DCR at Temperature calculator.


  • L = RoHS compliant tin-silver-copper over silver-platinum-glass frit.
  • S = non-RoHS tin-lead (63/37). (Special order, added cost)
