To have a leader and trailer added ($25 charge), use code letter C instead. 

   - **D** = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked(1000 parts per full reel). 

2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A or equivalent. 

3. DCR measured on a micro-ohmmeter. 

4. SRF measured using an Agilent/HP 8753D network analyzer and an Agilent/HP 16193A test fixture. 

5. DC current at which the inductance drops the specified amount from its value without current. 

6. Current that causes the specified temperature rise from 25°C ambient. 

7. Electrical specifications at 25°C.

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
