The excellent coupling coefficient (k

MSD7342 series of coupled inductors ideal for use in

SEPIC applications. In SEPIC topologies, the required

inductance for each winding in a coupled inductor is

half the value needed for two separate inductors, allow-

ing selection of a part with lower DCR and higher

current handling.

These inductors provide high inductance, high efficiency

and excellent current handling in a rugged, low cost part.

They can also be used as two single inductors con-

nected in series or parallel, as a common mode choke

or as a 1 : 1 transformer.

Core material Ferrite

Terminations RoHS compliant matte tin over nickel over phos

bronze. Other terminations available at additional cost.

Weight 0.76 – 0.87g

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.

Packaging: –40°C to +80°C

Winding to winding isolation 200 Vrms

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 250/7 reel; 1000/13 reel Plastic tape: 16 mm wide,

0.4 mm thick, 12 mm pocket spacing, 4.9 mm pocket depth

PCB washing Only pure water or alcohol recommended
