Notes
- When ordering, please specify termination and screening codes: e.g. ST563PRC232MLZ.
- Inductance measured at 500 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD-A fixture in an Agilent/HP 4284A LCR meter or equivalent.
- SRF measured on an Agilent/HP 8753ES.
- DC current at 25°C that causes a 30% (typ) inductance drop for ST563PRC and 20% (typ) inductance drop for ST550PRT from its value without current.
- Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
Termination:
- L = Tin-silver over copper.
- T = Tin-silver-copper (95.5/4/0.5). (Special order, added cost)
- S = Tin-lead (63/37). (Special order, added cost)
Screening:
- Z = Unscreened
- Y = Unscreened (SLDC Option A)
- W = Unscreened (SLDC Option B)
- H = Coilcraft CP-SA-10001 Group A
- G= Coilcraft CP-SA-10001 Group A (SLDC Option A)
- D = Coilcraft CP-SA-10001 Group A (SLDC Option B)
Custom screening also available.

Resistance to soldering heat:
Max three 40 second reflows at +260°C, parts cooled to room temperature between cycles.
Refer to Soldering Coilcraft Components before soldering.
PCB Washing:
Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. See Doc787_PCB_Washing.pdf.
