The YA9219 series is a surface mount wideband RF transformer designed for high-frequency signal transmission with 300 Vrms one-minute isolation between primary and secondary windings. It is AEC-Q200 qualified and operates over an ambient temperature range of -40°C to +125°C. The component uses ferrite core material with RoHS-compliant tin-silver-copper terminations and weighs 250-270 mg. It is packaged in 1000-piece 13-inch reels with 16 mm wide plastic tape, 0.35 mm thickness, 12 mm pocket spacing, and 5.0 mm pocket depth. Moisture sensitivity level is 1, and it withstands three reflow cycles at 260°C for 40 seconds each. Primary inductance is 127 µH minimum at 10 kHz, secondary inductance is 65 µH minimum, and the turns ratio is 1:0.714. Pin 6 and pin 4 must be connected on the PCB.
The YA9219-AL Wideband Transformer with an integrated common-mode choke combines high-speed signal transmission, isolation, and effective common-mode noise filtering in a single compact component. This integrated design helps simplify PCB layout, save valuable board space, and ensure compliance with EMI/EMC requirements, while maintaining the high performance required for 10GBASE-T1 Ethernet applications.
