Isolation voltage

Dimensions in mm.

DC isolation voltage: 1000 V.

Contacts are applied on the edge of the ring core, which is

also the critical point for the winding operation.

Notes

1. Due to the rectangular BH-loop of 3R1, inductance values strongly depend on the magnetic state of the ring core and

measuring conditions. Therefore no A_Lvalue is specified. For the application in magnetic amplifiers A_Lis not a critical

parameter.

2. Ring cores in 3E5 are lacquered (polyurethane) and have different dimensions:

Outside diameter = 9.3 ±0.4 mm; inside diameter = 5.75 ±0.3 mm; height = 3.25 ±0.3 mm; flame retardant in

accordance with “UL 94V-2”; UL file number E 192048.

3. Ring cores in 3E6 are coated with parylene C and have different dimensions:

Outside diameter = 9.0 ±0.2 mm; inside diameter = 6.0 ±0.2 mm; height = 3.0 ±0.15 mm.

WARNING

Do not use grade 3R1 cores close to their mechanical resonant frequency. For more information refer to “3R1” material

speciﬁcation in this data handbook.
