Common Mode Chokes are member of signal transformer family used in electrical and electronic circuits in order to suppress conducted interference and common mode noise. Among them, the ACM1513-551-2PL-T is a common mode choke specifically designed to reduce external electromagnetic interference (EMI) emissions from electrical/electronic circuits that are connected to Switch mode power supplies. It is a compact but efficient electromagnetic filter that is effective for frequencies up to 2MHz. In the following we look at the application fields and working principle of ACM1513-551-2PL-T.

Application fields of ACM1513-551-2PL-T

The unique design of ACM1513-551-2PL-T make it an effective EMI noise reducer in switching power supplies. This choke is well-known for its excellent noise rejection capabilities and wide operating temperature. ACM1513-551-2PL-T is mainly used in power supply circuits, automotive circuits, audio and video systems, data processing systems, RF systems, instrument controllers, computer motherboards, telephone lines, networking switches, customer service controls, and other electronic equipments.

Working Principle of ACM1513-551-2PL-T

The working principle of ACM1513-551-2PL-T is based on the fact that choke consists of a coil of conductive wire. The winding of the coil is used to create a high molecular permeability in the core, and to generate a low resistance path for ac current, but a high impedance path for dc current. The induction of the coil reverses the phase of the current, resulting in an out-of-phase current flow which cancels out the interfering EMI noise. This helps in suppressing conducted interference from being conducted onto adjacent equipment. In addition, the unique design of ACM1513-551-2PL-T also effectively filters out common mode noise generated from external sources.

The high permeability of the core of the ACM1513-551-2PL-T makes it possible to get excellent EMI rejection even at very high frequencies. The effectiveness of this suppressor is further improved by the low insertion loss and high voltage protection provided by the unique winding design of the core. This differential choking action of the ACM1513-551-2PL-T ensures optimal noise suppression along with minimal Electromagnetic radiation generated.

Conclusion

The ACM1513-551-2PL-T is a common model choke designed to reduce external electromagnetic interference (EMI) emissions from electrical/electronic circuits that are connected to Switch mode power supplies. It is an ideal choice for suppressing conducted interference from being conducted onto adjacent equipment. The high molecular permeability of the core, low insertion loss, high voltage protection, and differential choking action of ACM1513-551-2PL-T make it an effective EMI noise reducer for frequencies up to 2MHz. It is mainly used in automotive circuits, data processing systems, RF systems, instrument controllers, and other electronic equipments.
