Notes
- When ordering, please specify termination and testing codes: ST534PMM231MLZ.
- Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent.
- DCR is measured on a micro-ohmmeter at points indicated in the dimensional diagram.
- This information is for design purposes only and shall not be tested during screening.
- DC current at 25°C that causes a 20% (typ) inductance drop 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 = Matte tin over nickel 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 = Group A screening per Coilcraft CP-SA-10001
- G = Coilcraft CP-SA-10001 Group A (SLDC Option A)
- D = Coilcraft CP-SA-10001 Group A (SLDC Option B)
