SMT Data Line EMI Filter

  • Low profile (<5.0 mm) compact surface mount package
  • Ideal for use to suppress up to 100 MHz common mode noise for differential signal line filtering
  • Provides greater than 40 dB common mode noise attenuation
  • 500 Vrms Isolation (hipot)
  • Refer to Designing Common Mode Filters for design guidance.
  • RoHS-compliant. 260°C compatible. Tin-silver-copper over tin over nickel over phos bronze terminations.

1 When ordering, please specify packaging code: e.g. CR7856-ALC
Packaging: C = 7" machine-ready reel
EIA-481 embossed plastic tape (250 per full reel).
B = Less than full reel
In tape, 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 Frequency at which the differential mode attenuation equals 3 dB
3 Inductance shown for each winding, measured at 10 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4263B LCR meter or equivalent.
4 Irms: Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
5 DCR is specified per winding at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
6 Isolation (hipot) measured with 3 mA applied for two seconds
7 Ambient temperature range: −40°C to +85°C with Irms current
8 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
9 Maximum part temperature: +125°C (ambient + temperature rise)
10 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.
11 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. More info.
