1. Open Circuit Inductance (OCL) Test Parameters: 1.0 MHz, 0.1 Vrms, 0.0 Adc, +25 °C

PCB layout, trace thickness and width, air-flow, and proximity of other heat generating components will affect the

temperature rise. It is recommended that the temperature of the part not exceed +125 °C under worst case operating

conditions verified in the end application.

4. DCR tested from pins (1-2) and pins (4-3)

5. Part Number Definition: FPT705-xxx-R

FPT705 = Product code and size

xxx= Inductance value in nH,

-R suffix = RoHS compliant

Dimensions (mm)

Packaging information (mm)

Supplied in tape and reel packaging, 1,000 parts per 13” diameter reel

Part marking: FPT705, xxx=inductance value in nH, wwllyy= date code R= revision level

Soldering surfaces to be coplanar within 0.10 millimeters

DCR is measured from point “a” to point “b”

Pins 2 and 4 are connected through the PCB trace

Do not route traces or vias underneath the inductor
