A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
It provides electrical isolation, impedance matching, and common-mode noise rejection for differential data signals, ensuring signal integrity and compliance with standards.
Typical values include a turns ratio of 1:1, inductance of 350 µH at 100 kHz, leakage inductance of 0.5 µH max, interwinding capacitance of 30 pF max, and isolation voltage of 1500 V RMS per IEC 60950.
It uses electromagnetic induction with a ferrite core. The primary and secondary windings are galvanically isolated, transferring signals via a changing magnetic field without direct electrical connection.
Verify model-specific values for turns ratio, inductance, isolation voltage, operating temperature, and package size with the manufacturer or supplier, as listed values are reference ranges.
