SEMI-POTTED VERTICAL STYLE
Common Mode Inductors
Single Layer Windings with
Spacers specially designed by
Rhombus Industries to provide
3mm Creepage and Clearance
for International Safety
Compliance.
Operating Temperature: These
parts are made
with materials rated for 1300C
minimum, and these
components can be safely
operated up to 130OC.
Designed to prevent noise emission
in switching power supplies at input.
Windings balanced to 1%
Isolation 1250 VRMS
Materials used in the construction
of these parts are UL 94 VO and
are rated at 130o C or better
* AMBIENT + TEMPERATURE
RISE. In addition, inductance
will be effected by an increase
in temperature. Typically:
20% increase to 500C
40% increase to 1000C
65% increase to 1300C
Temperature Range -400C to +1300C
