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. See Doc787_PCB_Washing.pdf.

1. 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.
