XAR7030 Series

Raised Power Inductors

Our unique off-the-board, raised XAR7030 inductor design provides clearance for parts to be mounted underneath. This and magnetic shielding allow for very high density packaging in VRM/VRD and power supply applications.. XAR7030 inductors feature soft saturation for high peak current handling, and composite construction to minimize audible buzzing. These high current, exceptionally low DCR inductors are RoHS-compliant, halogen free, and are suitable for operation up to 165°C.

Unique off-the-board design provides 1.5 mm clearance for parts to be mounted underneath
Excellent current handling, exceptionally low DCR
Magnetically shielded for high density applications
Soft saturation, perfect for VRM/VRD applications
Composite construction minimizes audible buzzing
No thermal-aging

Notes

When ordering, please specify packaging code: e.g. XAR7030-103MEC
Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
SRF measured using an Agilent/HP 4395A or equivalent.
Isat: DC current at 25°C that causes an inductance drop of 30% (typ) from its value without current. Temperature derating curves.
Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.
Irms testing was performed on 0.75 inch wide × 0.25 inch thick copper traces in still air. Temperature rise is highly dependent on many factors including pcb land pattern, trace size, and proximity to other components. Therefore temperature rise should be verified in application conditions.

Termination:

RoHS compliant matte tin over nickel over phos bronze.

Packaging:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (250 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C.
D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (1000 parts per full reel).
