High-Reliability Chip Inductors ML312RAA
0603 CHIP INDUCTORS
Small size, exceptional Q and high SRFs make these
inductors ideal for high frequency applications where
size is at a premium. They also have excellent DCR and
current carrying characteristics.
This robust version of Coilcraft’s standard 0603CS series
features high temperature materials that allow operation
in ambient temperatures up to 155°C.

1. When ordering, please specify tolerance and testing codes:
ML312RAAR39JLZ
Tolerance: F = 1% G = 2% J = 5%
Testing: Z = COTS
H = Group A screening per Coilcraft CP-SA-10001
N = Group A screening per Coilcraft CP-SA-10003
2. Inductance measured at 250 MHz using a Coilcraft SMD-A test fixture and Coilcraft-provided correlation pieces with an Agilent/HP 4286A impedance
analyzer or equivalent.
3. Q measured at the same frequency as inductance using an Agilent/HP 4291A with an Agilent/HP 16197A test fixture or equivalents.
4. SRF measured using an Agilent/HP 8753ES network analyzer and a Coilcraft CCF1232 test fixture.
5. DCR measured on a Keithley 580 micro-ohmmeter and a Coilcraft CCF1010 test fixture.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
