KA4909-AL

Bias Injection Choke

符合RoHS AEC-Q flag
Coillcraft's KA4909-AL bias injection choke was developed for use with Texas Instruments DS90UB901Q serializer and DS90UB902Q deserializer for Low-Voltage Differential Signaling (LVDS) applications. It provides more than 1 kOhm of impedance from 1 MHz – 800 MHz.
  • 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.
  • AEC-Q200 Grade 3 (−40°C to +85°C)

注释
  1. When ordering, please specify packaging codes: e.g. KA4909-ALC
  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

端子:

  • RoHS compliant tin-silver-copper over tin over nickel over phos bronze.

包装:

  • C = 7" machine-ready reel
    EIA-481 embossed plastic tape (250 parts per full reel).
  • B = Less than full reel
