Shielded Power Inductor

For NSC LM315x

SIMPLe SwItCher

• Designed specifically for National Semiconductor LM315x

SIMPLE SWITCHER

Controllers for applications with output

current up to 12 A.

• L1 on NSC Demonstration Board LM3152-3.3

• Soft saturation makes it ideal for use in multi-phase VRM/VRD

regulators and high current/high frequency DC/DC converters.

• Flat wire construction for low DCR

• The materials used eliminate all thermal aging issues

Core material

Powdered iron

Terminations

RoHS compliant tin-silver over copper. Other termina-

tions available at additional cost.

Weight

3.44 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.

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)

Mean Time Between Failures (MTBF)

26,315,789 hours

Packaging

100/7″ reel; 500/13″ reel Plastic tape: 24 mm wide,

0.4 mm thick, 16 mm pocket spacing, 7.5 mm pocket depth

PCB washing

Only pure water or alcohol recommended

1. When ordering, please specify

termination

and

packaging

codes:

HA3778-ALC

Termination: L

RoHS compliant tin-silver over copper.

Special order: T

= RoHS tin-silver-copper

(95.5/4/0.5) or

= non-RoHS tin-lead (63/37).

Packaging: C

= 7″ machine-ready reel. EIA-481 embossed plastic

tape (100 parts per full reel).

= Less than full reel. In tape, but not machine ready.

To have a leader and trailer added ($25 charge),

use code letter C instead.

= 13″ machine-ready reel. EIA-481 embossed plastic

tape. Factory order only, not stocked (500 parts per

full reel).

2. Inductance measured at 500 kHz, 0.1 Vrms, 0 Adc using a Coilcraft

SMD-A fixture in an Agilent/HP 4284A LCR meter or equivalent.

3. SRF measured on an Agilent/HP 8753ES.

4. DC current at which the inductance drops 30% (typ) from its value with-

out current.

5. Current that causes a 40°C temperature rise from 25°C ambient.

6. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
