Notes
  1. When ordering, please specify screening code: ST512PJB106MRZ.
  2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4192A.
  3. DCR measured on a micro-ohmmeter.
  4. SRF measured using an Agilent/HP 8753ES or equivalent.
  5. DC current at 25°C that causes the specified inductance drop from its value without current.
  6. Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.

Screening:

  • Z = Unscreened
  • Y = Unscreened (SLDC Option A)
  • W = Unscreened (SLDC Option B)
  • H = Group A screening per Coilcraft CP-SA-10001
  • G= Coilcraft CP-SA-10001 Group A (SLDC Option A)
  • D = Coilcraft CP-SA-10001 Group A (SLDC Option B)
All screening performed to the document’s latest revision.
Custom screening also available.
