0402FL

Low Profile Chip Inductors

Our 0402FL Series of wirewound ferrite chip inductors feature a low profile of 0.55 mm, which is 10% lower than competitive inductors. They were developed for cellular applications for use either as filter elements, as one-pole filters, or as RF chokes in the cellular bands, and are great for use in mobile and infrastructure equipment.

Maximum height reduced to 0.55 mm – 10% lower profile than competitive products
Developed for use in cellular applications:
As a filter element in bandstop and low pass filters
As a one pole filter or RF choke in cellular bands
Ideal for use in both mobile and infrastructure equipment
Ferrite construction for high current handling
Equally effective on-board or modular
Can also be used for ground-to-ground isolation

When ordering, please specify packaging code: e.g. 0402FL-561XJRW
Inductance measured at 7.9 MHz using a Coilcraft SMD-F test fixture and Coilcraft-provided correlation pieces with an Agilent/HP 4286 impedance analyzer.
SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture.
DCR measured on Cambridge Technology micro-ohmmeter and a Coilcraft CCF858 test fixture. For other operating temperatures, use this DCR at Temperature calculator.
Current that causes a 40°C temperature rise at 25°C. This information is for reference only and does not represent absolute maximum ratings. Because of their open construction, these parts will not saturate.
Maximum current that can be applied at 85°C.
Maximum current that can be applied at 125°C.
