1. When ordering, please specify termination and packaging codes:
DO1813H-473M
LD
Termination: L = RoHS compliant tin-silver over copper.
Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
Packaging:
D = 13
″ machine-ready reel. EIA-481 embossed plastic
tape, 1000 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.
2. Inductance tested at 0.25 Vrms, 100 kHz, 0 Adc.
3. DC current at which the inductance drops 30% (typ) from its value
without current.
4. Current that causes a 40°C temperature rise from 25°C ambient.
5. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
Designer’s Kit C331 contains 3 of each part
