1. Please specify termination and packaging codes:
SER1052-572MLD
Termination: L = RoHS compliant tin-silver over copper
(pins 1 and 2); matte tin over nickel over
phos bronze (pin 3).
Special order:
T = RoHS tin-silver-copper (95.5/4/0.5)
or S = non-RoHS tin-lead (63/37).
Packaging: C = 7machine-ready reel. EIA-481 em-
bossed plastic tape (200 parts per full
reel).
B = Less than full reel. In tape, but not
machine ready.
To have a leader and trailer added ($25
charge), use code letter C instead.
D = 13machine-ready reel. EIA-481 em-
bossed plastic tape. Factory order only,
not stocked (700 parts per full reel)
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an
Agilent/HP 4284A or equivalent.
3. DCR measured on a micro-ohmmeter.
4. SRF measured using an Agilent/HP 4395A network
analyzer and an Agilent/HP 16193A test fixture.
5. DC current at 25°C that causes the specified inductance
drop from its value without current.
Click for temperature derating information.
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.
Click for temperature derating information.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components”
before soldering.
