Notes
  1. When ordering, please specify screening code: e.g. MS648PTA472MSZ.
  2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4263B LCR meter or equivalent.
  3. DCR measured on a Keithley 580 micro-ohmmeter.
  4. SRF measured using an Agilent E5061 network analyzer and impedance option using fixture CCF1592 with mask 297A1751 and shim 297A1765.
  5. DC current at 25°C that causes a 10% (typ) inductance drop from its value without current.
  6. Current that causes the specified temperature rise from 25°C ambient. When Irms is greater than Isat, Isat is the more critical specification, and Irms is shown in gray type. See Temperature Rise vs Current curve below. 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 = Coilcraft CP-SA-10001 Group A
  • G = Coilcraft CP-SA-10001 Group A (SLDC Option A)
  • D = Coilcraft CP-SA-10001 Group A (SLDC Option B)
  • 1 = EEE-INST-002 (Family 1) Level 1
  • 2 = EEE-INST-002 (Family 1) Level 2
  • 3 = EEE-INST-002 (Family 1) Level 3
  • 4 = MIL-STD-981 (Family 04) Class B
  • 5 = MIL-STD-981 (Family 04) Class S
  • F = ESCC3201 (F4 operational life performed at 105°C)
  • Screening performed to the document’s latest revision.
  • Lot qualification (Group B) available.
  • Testing T and U have been replaced with more detailed codes 4, 5, and 1, 2, 3, respectively. Codes T and U can still be used, if necessary. Custom testing also available.
  • Country of origin restrictions available; prefix options G or F.
