Shielded Power Inductors - SER2900
• Same electrical specifications as Coilcraft’s SER2800
• Extremely low DCR; Current handling to >100 Amps
• Third mounting pad for greater stability and board adhesion
Core material Ferrite
Terminations Leads: RoHS compliant tin-silver over copper
Base pad: RoHS compliant gold over nickel over phos bronze
Other terminations available at additional cost.
Weight SER2915L–28.5g; SER2915H–29.7g; SER2918H–35.7 g
Ambient temperature –40°C to +85°C with Irms current, +85°C to
+125°C with derated current
Storage temperature Component: –40°C to +125°C.
Tray 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

S = non-RoHS tin-lead
(63/37).
2. Inductance measured at 500 kHz, 0.1 Vrms,
0 Adc on an Agilent/HP 4284A LCR meter or
equivalent.
3. DCR measured on a Keithley 580 micro-
ohmmeter or equivalent.
4. SRF measured using an Agilent/HP 4395A
network analyzer and an Agilent/HP 16092A
test fixture.
5. Peak dc current at which the inductance
drops the specified amount from its value
without current. When Isat rating is less than
Irms, Isat is the more critical specification.
6. Current that causes the specified tempera-
ture rise from 25°C ambient. When Irms is
greater than Isat, Isat is the more critical
specification, and Irms is shown in gray type.
See Temperature Rise vs Current curve on
next page.
