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
on-line at http://order.coilcraft.com.
1. When ordering, please specify packaging code:
2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc on Agilent/HP 4284A
3. SRF measured using Agilent/HP 4191A or equivalent.
4. DC current at which the inductance drops 10% (typ) from its value
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.
Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic
LC meter or equivalent.
