PACKAGING SPECS:
Bulk only
NOTES:
Custom designs are available to meet your specic
requirements; please contact factory
Operating Temperature Range:
-55°C to +125°C
Current Rating is based on a 35°C maximum
temperature rise at an ambient temperature of 90°C
Saturation Current is the approximate value that will
cause a 10% drop in inductance as indicated in the table
Weight Max: 118 grams
Marking: GOWANDA; DB4; -xxxx (dash number)
GOWANDA
DB4-102
When ordering, specify termination:
DB4-102LF
Tolerance: All part numbers provide 10% tolerance
on inductance
Termination: LF = RoHS compliant tin-silver copper
over copper
