D1738-AL
This chip inductor is designed for the needs of the high
frequency designer. Its ceramic construction delivers
excellentSRFandQvalues. Thenon-magneticcoilform
also ensures the utmost in thermal stability, predictabil-
ity and batch consistency. This part is RoHS compliant,
compatible with 260°C soldering.

1. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/HP
4286A impedance analyzer with Coilcraft-provided correlation pieces.
2. Q measured using an Agilent/HP 4291A with an Agilent/HP 16193 test
fixture.
3. SRF measured using an Aglilent/HP 8753D network analyzer and a
Coilcraft SMD-D test fixture.
5. Average current for a 15°C rise above 25°C ambient.
6. Operating temperature range −40°C to +125°C.
7. Electrical specifications at 25°C.
See Qualification Standards section for environmental and test data.
See Color Coding Section for part marking data.
4. DCR measured on a Cambridge Technology micro-ohmmeter and a
Coilcraft CCF840 test fixture.
