2. Handling Warnings
（1）The standard noise filter cannot be used between
a general-purpose inverter and a motor.
Please select a specialized filter for the general-purpose
inverter output side.

Both positive
block terminal earth terminals are
connected to a metal case, and as a result, both can be
connected to the frame ground of the electronic device.
They can also be used as grounding terminals.

frequencies (50/60 Hz).
If used at a frequency other than commercial frequencies,
inquire with a TDK-Lambda sales representative in
advance.
（3）The DC line specialized noise filter cannot be
used on AC lines.
A three-phase three-line noise filter can be used in single-
phase three-line systems.

（4）Leakage Current
The noise filter has internal line bypass capacitor built-in,
and as a result, leakage current flows.
When selecting an electric leakage breaker, take into
consideration the leakage current of the noise filter.
（5）Permissible Inrush Current
If the back of the noise filter is connected to a switching
power supply, a large inrush current will flow when the

input power is turned on.
If the inrush current duration is approximately one-
quarter cycle of a 50/60 Hz commercial power supply,
the permissible current value is 50 times as much as the
rated current.

3. Noise Filter Safety Standards
Each country has the following safety standard on noise
filters.
Refer to each product catalog for acquired standards.
United States: UL1283
Canada: CSA C22.2 No.8
Europe: EN60939
CE Markings
Devices (final set products) that meet European EMC
Balun
4. Methods of Measuring Characteristic Data
（1）Method of measuring insertion attenuation
Measurement of attenuation when an EMC filter is
inserted in a circuit generally complies with the Military
standard (MIL-STD-220), but many Power Line EMC
Filters of TDK-Lambda brand use are measured in
accordance with the following measurement method.

As a result, most of the products in this catalog that
categorized as component do not apply CE markings.
If you look for the products in this catalog for use in
CE marking devices, please select European safety
standards certificated products.
CCC Certification
Noise filters are exempt from CCC certification.

The baluns in the circuit contain change-over switches so that stand-alone
measurements can be made for the differential mode (symmetrical wave)
portion and the common mode (asymmetrical wave) portion.
