BiasInjectionChoke  
KA4909-AL  
Developed for use withTexas Instruments DS90UB901Q serial-  
izer and DS90UB902Q deserializer for Low-Voltage Differential  
Signaling (LVDS) applications.  
This center tapped inductor provides over 1 kOhm impedance  
from 1 MHz – 800 MHz.  
Can be used with additional 10 µH and 1 µH inductors to achieve  
even wider band differential signal rejection.  
AEC-Q200 Grade 3 (–40°C to +85°C) qualified  
Core material Ferrite  
Terminations RoHS compliant tin-silver-copper over tin over nickel  
over phos bronze.  
Weight 220 mg  
Ambient temperature –40°C to +105°C  
Storage temperature Component: –40°C to +105°C.  
Tape and reel packaging: –40°C to +80°C  
Resistance to soldering heat Max three 40 second reflows at  
+260°C, parts cooled to room temperature between cycles  
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /  
85% relative humidity)  
Failures in Time (FIT) / Mean Time Between Failures (MTBF)  
60 per billion hours / 16,666,667 hours, calculated per Telcordia SR-332  
Packaging 250/7reel; 1000/13reel Plastic tape: 16 mm wide,  
0.35 mm thick, 12 mm pocket spacing, 5.0 mm pocket depth  
PCB washing Tested with pure water or alcohol only. For other solvents,  
see Doc787_PCB_Washing.pdf

1. When ordering, please specify packaging code:  
KA4929-ALC  
Packaging: C = 7machine ready reel. EIA-481 embossed plastic  
tape, 250 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 C instead.  
D = 13machine ready reel. EIA-481 embossed plastic  
tape. Factory order only, not stocked (1000 parts  
per full reel).  
2. Inductance tested from pins 1 to 3 at 100 kHz, 0.007 Vrms, 0 Adc.  
3. DCR is tested from pins 1 to 3  
4. Current that causes a 20°C rise from 25°C ambient.  
5. Electrical specifications at 25°C.  
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
