Document 609-1
Revised 01/22/10
Designer’s Kit C427 contains 3 each of all values
Core material Ferrite
Terminations RoHS compliant tin-silver over copper. Other
terminations available at additional cost.
Ambient temperature –40°C to +125°C with
Irms current, +125°C
to +165°C with derated current
Storage temperature Component: –40°C to +125°C.
Packaging: –40°C to +80°C
Resistance to soldering heat Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
85% relative humidity)
Failures in Time (FIT) / Mean Time Between Failures (MTBF)
38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332
PCB washing Only pure water or alcohol recommended
• Designed for high current power supply applications
• Flat wire windings provide exceptionally low DCR
• Specially formed terminations provide small footprint
•
Isat ratings as high as 85 A
• Other inductance, DCR, height combinations are possible
1. When ordering, please specify termination and packaging codes:
SER1410-202M
ED
Termination: E = RoHS compliant tin-silver over copper.
Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
Packaging:
D =13
″ machine-ready reel. EIA-481 embossed plastic
tape.
B = Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge), use
code letter D instead.
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP
4263B LCR meter or equivalent.
3. DCR measured on a Keithley 580 micro-ohmmeter or equivalent.
4. SRF measured using an Agilent/HP 8753D network analyzer and a
Coilcraft SMD-D test fixture.
5. DC current at which the inductance drops the specified amount from its
value without current.
6. Current that causes the specified temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
