TCM1210-301-2P-T

Common Mode Chokes (CMCs) are passive devices used to provide isolation in electronic circuits by blocking undesired electromagnetic interference (EMI) and attenuating conducted common mode noise along a given circuit. They are part of the electromagnetic compatibility (EMC) equipment used to protect a system from the adverse effect of external electromagnetic devices. The CMCs can come in various forms depending on the type of filtering required and the location where the device is installed.The TCM1210-301-2P-T is a common mode choke designed for compact, space constrained applications such as mobile devices, consumer electronics, and control systems. It is a two-phase wire-wound core type with two separate windings that provide excellent common-mode noise suppression at high frequencies. This type of device is ideal for filtering high frequency common-mode noise from power and communication lines.The TCM1210-301-2P-T operates in the frequency range from 1 MHz to 3GHz, providing excellent suppression characteristics in common-mode noise with low insertion loss and high differential-mode noise attenuation. It is also designed to handle high surge currents that can occur in mobile devices and other space-constrained applications, and its two-phase structure allows it to be used in both series and parallel configurations.A working principle of the TCM1210-301-2P-T is the use of two separate windings that offer a series of impedance points for insulating common-mode conducted noise. Each winding creates an inductive voltage drop for high-frequency common-mode noise, diverting the energy away from the components that are being protected. The inductor’s core material also offers a low-resistance path for high-frequency common-mode current to pass through.The TCM1210-301-2P-T has a wide range of applications in various industries with space-constrained designs. In mobile devices, its compact size and high surge-current handling capability make it suitable for antenna tuning, filtering incoming and outgoing signals, and protecting signal paths from conducted common-mode noise. It is also suitable for use in medical equipment, factory automation, LED lighting fixtures, motor drives, solar panels, and cable TV equipment.CMCs are designed to be used in conjunction with other electromagnetic compatibility (EMC) equipment such as ferrite beads and transient voltage suppression (TVS) diodes to provide additional filtering and protection from electrostatic discharge (ESD) events. CMCs are also highly effective in suppressing conducted common-mode noise from power supplies, battery charging circuits, and data lines.When selecting a CMC for a given application, it is important to consider the device’s operating frequency range, insertion loss, and common-mode noise suppression characteristics. The operating temperature range should also be taken into account, as this will affect the device’s life span and performance. Additionally, it is important to ensure that the CMC is compatible with the components it is being used to protect.In conclusion, the TCM1210-301-2P-T is an ideal CMC for space-constrained applications and can provide excellent common-mode noise suppression at high frequencies. It is designed to handle high surge currents, and its two-phase structure allows it to be used in both series and parallel configurations. When selecting a CMC for a given application, it is important to take into consideration the device’s operating frequency range, insertion loss, and common-mode noise suppression characteristics.
