ST336RAD Series
Chip Inductors for Critical Applications
These inductors provide exceptional Q values, even at high frequencies. They have a ceramic body and wire wound construction to provide the highest SRFs, tight inductance tolerance and batch consistency.
This robust version of Coilcraft’s standard 0805HQ series features high temperature materials that allow operation in ambient temperatures up to 155°C.

Notes
- When ordering, specify tolerance, termination and testing codes: e.g. ST336RAD51NGLZ.
- Inductance measured using a Coilcraft SMD-A fixture in an Agilent/HP 4286 impedance analyzer or equivalent with Coilcraft-provided correlation pieces.
- Q measured at the same frequency as inductance using an Agilent/HP 4291A with an Agilent/HP 16197 test fixture or equivalents.
- SRF measured using an Agilent/HP 8753ES network analyzer or equivalent and a Coilcraft SMD-D test fixture.
- DCR measured on a Keithley 580 micro-ohmmeter or equivalent and a Coilcraft CCF858 test fixture.
Tolerance:
- F = 1%
- G = 2%
- J = 5%
Termination:
- L = Silver-palladium-platinum glass frit.
- S = Tin-lead (63/37) over silver-platinum-glass frit. (Special order, added cost)
- T = Tin-silver-copper (95.5/4/0.5) over silver-platinum-glass frit. (Special order, added cost)
Testing:
- Z = Unscreened
- H = Group A screening per Coilcraft CP-SA-10001
Custom screening also available.
