## **SMT Data Line EMI Filters – CDF**
- See our PDLF series for 4, 3 and 2-line EMI filters
- Exceptional common mode noise attenuation from 15 MHz to 300 MHz; passes signal line data below 300 MHz with minimal attenuation
- DC current capacity of 500 or 100 mA.
- Excellent electrical isolation – 300 Vrms
## **Core material** Ferrite
**Terminations** RoHS compliant tin-silver-copper over tin over nickel over phos bronze. Other terminations available at additional cost. **Weight** 330 – 345 mg

1. When ordering, please specify **termination** and **packaging** codes: ~~—~~ **CDF 8500LD Termination L** = RoHS compliant tin-silver-copper over tin over nickel over phos bronze. Other terminations available at additional cost.
- **Special order: S** = non-RoHS tin-lead (63/37).
- **Packaging D** = 13″ machine ready reel. EIA-481 embossed plastic tape (1000 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 D instead.
2. Frequency at which the differential mode attenuation equals −3 dB
