The new 0805USBN Series common mode chokes measure just 2.0 x 1.2mm, with a maximum height of 0.93mm, making them the lowest profile 0805 common mode chokes available. They offer up to 6.5 GHz differential model 3 dB cutoff frequency and up to 35 dB common mode noise attenuation across a wide frequency range up to GHz band.

| 1 | When ordering, please specify packaging code: e.g. 0805USBN-222MRC |
| Packaging: | C = 7″ machine-ready reel EIA-481 embossed plastic tape (2000 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 (7500 parts per full reel). |
| 2 | Inductance measured at 100 MHz, with windings connected in parallel, using an Agilent/HP 4286A impedance analyzer and a Coilcraft SMD-A fixture. | |
| 3 | DCR is specified per winding at 25°C. For other operating temperatures, use this DCR at Temperature calculator. | |
| 4 | Irms: Current per winding that causes a 15°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. | |
| 5 | Ambient temperature range: | −40°C to +125°C |
| 6 | Storage temperature range: | Component: −40°C to +140°C Tape and reel packaging: −40°C to +80°C |
| 7 | Maximum part temperature: +140°C (Ambient + temperature rise) | |
| 8 | 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. | |
| 9 | 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. | ||
