SMT Power Inductors - MSS1278 Series

The MSS1278 Series provides high inductance and high

efficiency in a rugged, low cost part.

The magnetic shielding and small footprint of these

inductors allows high density mounting. The flat top

ensures reliable pick and place handling.

They’re ideal for use in DC-DC converters, LCD panels,

and portable devices where low cost and high reliabilty

are critical.

In addition to the standard values shown, Coilcraft can

custom-engineer versions to meet specific applications.

Coilcraft

Designer’s Kit C180

contains samples of all

values shown. To order, contact Coilcraft or purchase

1. When ordering, please specify

packaging

code:

MSS1278-105KXD

Packaging: D

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

tape (500 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 D instead.

2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc on Agilent/HP 4284A

LC meter or equivalent.

3. SRF measured using Agilent/HP 4191A or equivalent.

4. DC current at which the inductance drops 10% (typ) from its value

without current.

5. Average current for temperature rise from 25°C ambient.

6. Operating temperature range

−40°C

to +85°C.

7. Electrical specifications at 25°C.

See Qualification Standards section for environmental and test data.
