3. DCR is measured on a micro-ohmmeter at points indicated in the
diagram.
1. When ordering, specify conductors, termination and testing codes:
ST515PMM101KLZ
Conductors: M= Single conductor; N = dual conductor
Termination: L = Matte tin over nickel over copper
Special order: T = RoHS tin-silver-copper
Points used for measuring DCR
(95.5/4/0.5) or S = non-RoHS tin-lead (63/37).
4. SRF measured using an Agilent/HP 8753ES network analyzer and a
Coilcraft SMD-D fixture.
5. DC current at which the inductance drops 20% (typ) from its value
without current.
6. Current that causes a 40°C rise from 25°C ambient.
7. Electrical specifications at 25°C.
Testing:
Z = COTS
H = Group A screening per Coilcraft CP-SA-10001
2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B
LCR meter or equivalent.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
