Notes
  1. When ordering, please specify packaging code: e.g. UWB4-45EC
  2. Inductance measured at 100 KHz, 0.1 V, 0 Adc on an Agilent/ HP 4192 or equivalent.
  3. DCR measured at 25°C on a micro-ohmmeter. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.

Termination:

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