The CMF Series provides exceptional common-mode suppression and exceptional stray inductance to suppress differential-mode noise. In effect the CMF Series combines the features of two separate components into one. They are compact in size and are available in either vertical configuration, using minimal board area, or horizontal configuration for low profile applications. They are frequently used in LED lighting, electronics ballast and switch-mode power supplies.

Triad’s CMT Series Common Mode Inductors provide common mode EMI suppression for power supplies. They feature our precision coil windings to eliminate noise and to minimize the AC line transmitted interference often created by high frequency switching power supplies. They also meet various regulatory requirements and are constructed with UL rated 130°C materials.

Highly dependable Triad common mode EMI suppression inductors are used in various types of power supplies to eliminate noise common to all lines. These units also provide effective differential mode filtering. Designed to meet most regulatory requirements, they minimize AC line transmitted interference often created by high frequency switching power supplies. Normally placed close to the input source, these compact inductors are constructed with UL rated 130 ºC materials.

Common-mode choke coils are useful in a wide range of applications for the prevention of electromagnetic interference (EMI) and radio frequency interference (RFI) from power supply lines and for prevention of malfunctioning of various electronic equipment. Features include low leakage flux, high self-resonant frequency, high impedance at applicable frequency and low stray capacitance in section winding.

Triad toroidal inductors are specifically designed to minimize transients. These devices store energy, and therefore, condition the output signal by leveling out the current waveform providing a more stable current supply. Generally used in high frequency circuits, our standardized design provides an economical solution in differential mode applications or as an output inductor.

Triad high current rod core inductors provide cost effective energy storage. By conditioning the output signal, the inductor smoothes out the current waveform to provide a more stable current. These low cost inductors are designed to be compatible with automated P.C.B. installation.
