1. When ordering, please specify a

packaging code:

C1350-ALD

Packaging: D = 13

″ machine ready reel. EIA-481 embossed plastic

tape (200 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.

The B0726-E and C1350-A ADSL transformers have

been approved by Broadcom for use with their BCM6335,

BCM6338, BCM6345, and BCM6348 ADSL CPE Modem

chipsets and their BCM6301 5-Volt Line Driver.

These transformers feature split windings for chip receive,

chip transmit and line side. They offer 1875 Vrms isolation,

low DC resistance, low leakage inductance and excellent

total harmonic distortion. Their compact design makes them

suitable for high density applications.

Coilcraft can also custom design transformers to meet

your specific requirements. For free evaluation samples,

contact Coilcraft or visit

www.coilcraft.com.

2. Inductance measured at 10 kHz, 0.1 Vrms, 0 Adc between pins 9 and 16

with pins 11 and 14 connected.

3. Leakage inductance measured at 100 kHz, 0.1 Vrms between pins 9 and

16 with all other pins shorted.

4. Capacitance tested between pins 1 and 16 with all other pins shorted.

5. Total harmonic distortion measured at 30 kHz.

6. Operating temperature range

−40°C to +85°C.

7. Electrical specifications at 25°C
