1. When ordering, please specify
testing
code:
MS433PYA222MSZ
Testing:
Z
= COTS
H
= Screening per Coilcraft CP-SA-10001
N
= Screening per Coilcraft CP-SA-10004
2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
3. DCR measured on a micro-ohmmeter.
4. SRF measured using an Agilent/HP 4395A or equivalent.
5. Typical dc current at which the inductance drops 30% from its value without current.
6. Typical current that causes the specified temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
Irms
Testing
Irms
testing was performed on 0.75 inch
wide × 0.25 inch thick copper traces in
still air.
Temperature rise is highly dependent on
many factors including pcb land pattern,
trace size, and proximity to other compo-
nents. Therefore temperature rise should
be verified in application conditions.
