1. When ordering, please specify packaging code:
DA2343-AL
D
Packaging:
D =13
″ machine-ready reel. EIA-481 embossed plastic
tape.
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. Inductance measured between pins 1 and 3 at 100 kHz, 0.1 Vrms,
0 Adc using an Agilent/HP 4284A impedance analyzer.
3. DCR is per winding.
4. Operating temperature range
40°C to +125°C.
5. Electrical specifications at 25°C.
See Qualification Standards section for environmental and test data.
802.3af specification:
18 dB min from 1 MHz to 40 MHz
16 dB min at 50 MHz
12 dB min at 80 MHz

This injector coil is designed for 30 Watt PoE applica-
tions. Return loss exceeds the requirements of 802.3af
specification for the entire frequency range. It maintains
OCL of 350 H up to 20 mA at +85°C ambient.
