KA4909-AL

Bias Injection Choke

Coilcraft'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

When ordering, please specify packaging codes: e.g. KA4909-ALC
Inductance measured from pin 1 to 3 at 100 kHz, 0.007 Vrms, 0 Adc
DCR measured from pin 1 to 3 at 25°C. For other operating temperatures, use this DCR at Temperature calculator
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. Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
D = 13″ machine ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (1000 parts per full reel).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C.
