KA4909-AL Bias Injection Choke 

  • AEC-Q200 Grade 3 (−40°C to +85°C) qualified
  • Provides over 1 kOhm impedance from 1 MHz – 800 MHz.
  • Developed for use with Texas Instruments DS90UB901Q serializer and DS90UB902Q deserializer for Low-Voltage Differential Signaling (LVDS) applications.
  • Can be used with additional 10 µH and 1 µH inductors to achieve even wider band differential signal rejection.
  • RoHS-compliant. 260°C compatible. Tin-silver (96.5/3.5) over copper terminations.
  • COTS Plus tin-silver-copper and tin-lead terminations available

1 When ordering, please specify packaging codes: e.g. 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" reel, machine-ready
EIA-481 embossed plastic tape. Factory order only, not stocked (1000 parts per full reel).
2 Inductance measured from pin 1 to 3 at 100 kHz, 0.007 Vrms, 0 Adc
3 DCR measured from pin 1 to 3 at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Irms: Current that causes 20°C temperature rise from 25°C ambient. Details
5 Ambient temperature range: −40°C to +105°C
6 Storage temperature range: Component: −40°C to +105°C
Tape and reel packaging: −40°C to +80°C
7 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
8 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. Other solvents.
