1. Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (150 parts per full reel). Quantities less than full reel available: intape (not machine ready) or with leader and trailer ($25 charge).
2. Inductance tested at 1 MHz, 0.1 Vrms, 0 Adc.
3. DCR measured on a micro-ohmmeter.
4. SRF measured using Agilent/HP 4395A or equivalent.
5. DC current at 25°C that causes an inductance drop of 30% (typ) fromits value without current.
Click for temperature derating information.
6. Current that causes the specified temperature rise from 25°C ambient.
This information is for reference only and does not represent absolutemaximum ratings. Click for temperature derating information.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

Irms (A)620°C rise 40°C rise1824Irms Testing
Irms testing was performed on 0.75 inch wide × 0.25 inch thickcopper 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.
