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. | ||
