1. When ordering, please specify packaging code:
B0434-ALD
2. Inductance measured on an Agilent/HP 4284 between pins 3 and 4 at
10 kHz, 0.1 Vrms.
3. Isolation measured from pin 1 to pin 3.
4. DC current at which inductance drops 10ꢀ (typ) from its value without
current.
Packaging: D = 13″ machine ready reel. EIA-481 embossed plastic
tape (200 parts per full reel).
B = Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge), use
code letter D instead.
5. Current that causes a 40°C rise from 25°C ambient.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
