NOTES:
Operating Temperature Range:
-55°C to +125°C
Current Rating
is based on a 35°C temperature
rise at an ambient temperature of 90°C
Saturation Current
is the approximate value that will
reduce the initial inductance by 5%
Weight Max:
0.15 grams
Marking:
GEC; XXX (dash #)
GEC
010
Epoxy-encapsulated for environmental protection and
superior strength to withstand all types of reflow
soldering
