Irms testing was performed on a
0.060″ thick pcb with 4 oz. copper
traces optimized to minimize
additional temperature rise.
Temperature rise is highly
dependent on many factors
including pcb land pattern,
trace size, and proximity to
other components. Therefore
temperature rise should be
verified in application conditions.

1. When ordering, please specify testing code:
ST541PYA682MLZ
Testing: Z = Unscreened
H = Group A screening per Coilcraft CP-SA-10001
All screening performed to the document’s latest revision
2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4192A.
3. DCR measured on a micro-ohmmeter.
4. SRF measured using an Agilent/HP 4395A or equivalent.
5. DC current at 25°C that causes a 30% (typ) inductance drop from its value without current.
6. Current that causes the specified temperature rise from 25°C ambient.This information is for reference only
and does not represent absolute maximum ratings.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
