Document 1223-1 Shielded Power Inductor CU8838-AL • Soft saturation makes it ideal for VRD/VRM applications • Special materials eliminate all thermal aging issues. Core material Iron Terminations RoHS tin-silver over copper. Weight 4.9 g Ambient temperature –40°C to +85°C with Irms current Maximum part temperature:The part may be operated without damage as long its temperature (ambient + self-heating) does not exceed +125°C. Storage temperature Component: –40°C to +125°C. Tape and reel 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 Packaging 800/13″ reel Plastic tape: 24 mm wide, 0.3 mm thick, 12 mm pocket spacing, 6.1 mm pocket depth PCB washing Tested to MIL-STD-202 Method 215 plus an additional aqueous wash.

When ordering, please specify packaging code: CU8838-ALD Packaging:D =13″ machine-ready reel. EIA‑481 embossed plastic tape (800 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 D instead. 2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD‑A fixture in an Agilent/HP 4284A LCR meter. 3. SRF measured using an Agilent/HP4291A impedance analyzer and a Coilcraft 16193 fixture. 4. DC current at which the inductance drops the specified amount from its value without current. 5. Current that causes the specified temperature rise from 25°C ambient. 6. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
