AIR CORE INDUCTORS

Document ML893-1 Revised 06/27/12

1. When ordering, please specify

testing code:

ML643RAU251MLZ

Testing: Z = COTS

H = Screening per Coilcraft

CP-SA-10001

N = Screening per Coilcraft

CP-SA-10003

C = Custom screening (please

specify when ordering)

2. Inductance measured at 1.0 MHz, 0.1 Vrms,

0 A using an Agilent/HP HP4291A imped-

ance analyzer with an Agilent/HP 16193A

test fixture or equivalents.

3. Q measured at specified frequency using

an Agilent/HP 4291A impedance analyzer

or equivalent and a Coilcraft CCF1244 test

fixture.

4. SRF measured using an Agilent/HP 8753

network analyzer or equivalent and a Coilcraft

CCF1199 test fixture.

5. Current that causes the specified tempera-

ture rise from 25°C ambient.

6. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount Com-

ponents” before soldering.

■
