Notes
- When ordering, specify tolerance, termination and testing codes: e.g. ST336RAG821JRZ.
- Inductance measured using a Coilcraft SMD-A fixture in an Agilent/ HP 4286A impedance analyzer with Coilcraft-provided correlation pieces.
- Tolerances in bold are stocked for immediate shipment.
- Q measured using an Agilent/HP 4291A with an Agilent/HP 16193 test fixture.
- SRF measured using an Agilent/HP 8720D network analyzer and a Coilcraft SMD -D test fixture.
- DCR measured on a Cambridge Technology micro-ohmmeter and a Coilcraft CCF858 test fixture.
- Current that causes a 15°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
Tolerance:
- G = 2%
- J = 5%
Termination:
- R = Matte tin over nickel over silver-platinum-glass frit.
- Q = Tin-silver-copper (95.5/4/0.5) over tin. (Special order, added cost)
- P = non-RoHS tin-lead (63/37) over tin. (Special order, added cost)
Testing:
- Z = Unscreened
- H = Group A screening per Coilcraft CP-SA-10001
Custom screening also available.
