Developed for use with Texas 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  250/7″reel; 1000/13″ reel  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:
KA4909-ALC
Packaging: C = 7″ machine 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 = 13″ machine 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.
