This surface-mount device delivers 315 nH minimum common mode inductance with a peak impedance of 1.22 kΩ at 1.5 GHz, achieving up to 25.2 dB common mode attenuation in the GHz range while maintaining a 0.93 GHz differential mode 3 dB cutoff frequency to preserve signal integrity. The 0805 form factor (2.03 mm × 1.27 mm × 1.4 mm) accommodates dense PCB layouts, with matte tin over nickel over silver-platinum-glass frit terminations ensuring solderability across multiple reflow cycles. Rated for 500 mA RMS current per winding with a maximum DC resistance of 0.32 Ω, the 0805USBF-502MRC operates across an ambient temperature range of −40°C to +125°C and withstands maximum part temperatures of 140°C. The AEC-Q200 qualification supports automotive infotainment and telematics implementations, while MSL 1 classification eliminates moisture-related handling constraints. Winding-to-winding isolation of 250 Vrms provides adequate voltage separation for consumer and industrial interfaces. Packaged on 8 mm embossed plastic tape compatible with standard pick-and-place equipment, this common mode filter addresses conducted and radiated emissions in high-speed data ports without compromising differential signal bandwidth. ## Specifications | Parameter | Value | |---|---| | Svhc | No SVHC (25-Jun-2025) | | Impedance | 1.22kohm | | Inductance | 315nH | | Product Range | 0805USBF Series | | Product Width | 1.27mm | | Qualification | AEC-Q200 | | Product Height | 1.4mm | | Product Length | 2.03mm | | Dc Current Rating | 500mA | | Dc Resistance Max | 0.32ohm | | Inductor Case / Package | - | | Operating Temperature Max | 125°C | | Operating Temperature Min | -40°C | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:2780235RL/) Web Sample Tools & Support page & buy software & FAQ Document 1270-1 ## **0805 Low Profile USB Common Mode Choke** - For noise suppression in super high speed signal lines: USB 3.x, HDMI 2.0, HDBaseT™, DisplayPort, DVI, etc.; and in high speed differential signal lines: USB 2.0, IEEE1394, LVDS, etc. - Suitable for USB-type C specification 1.0 - Up to 6 GHz differential mode 3 dB cutoff frequency; up to 30 dB common mode noise attenuation in GHz range **Core material** Ferrite **Environmental** RoHS compliant **Terminations** Matte tin over nickel over silver-platinum-glass frit. **Weight** 14.7 – 15.5 mg **Ambient temperature** –40°C to +125°C with I rms current. **Maximum part temperature** 140°C **Storage temperature** Component: –40°C to +140°C.
