1. When ordering, please specify testing code:
3. DCR measured on a micro-ohmmeter.
4. SRF measured using an Agilent/HP 8753D network analyzer.
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.

Testing: Z = Unscreened
H = Group A screening per Coilcraft CP-SA-10001
T = Screening per MIL-STD-981
U = Screening per EEE-INST-002
F = Screening per ESCC 3201
All screening performed to the document’s latest revision
Custom screening also available
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/
HP 4284A or equivalent.
