1. When ordering, please specify **packaging** code: 

## **Typical Attenuation** 

## **CQ7584-ALC** 

- **Packaging: 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). 

**==> picture [242 x 184] intentionally omitted <==**

   - **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. 

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. 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. 

6. Isolation (hipot) measured for two seconds. 

7. Electrical specifications at 25°C. 

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
