1.Inductance meansured at specified frequency, 0.1Vrms, 0 A using HP4287A LCRmeter or equivalent with SMD test fixture. RACE540/550@400MHz; RACE570/580@50MHz;
2. Inductance tolerance in bold are stocked for shipment.
3. Q meansured at specified test frequency, using HP4287A LCR meter or equivalent.
4. SRF meansured using HP8753 network analyzer and SMD test fixture.
5. Current that causes a 20°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
6. Electrical specification at 25°C ambient.
7. Resistance to soldering heat : Max three 40s reflows at +260°C, parts cooled to room temperature between cycles.
8. Temperature Coefficient of Inductance : +5 to +70 ppm/°C.
