EE4.6 SMD Current Sensing Transformers Ferrite High Frequency

EE4.6 SMD High frequency Current Sensing Transformers , SMD Current transformers

Feature:

• Turns Ratio: 1:20  1:30 1:50,1:70,1:100,1:150 available
• Sensed current up to 20 Amps
• Designed for use up to 1 MHz and above
• Very low primary resistance
• High frequency current transformers for SMPS appllications
• High-permeability ferrite current transformers
• Low-profile current transformers
• PCB mount current transformers
• Reliable linear performance transformers

Applications:

• Continuous AC current monitoring in switched-mode power supply
• Overload and short-circuit protection
• Current measurement in traction motor and battery management systems in conventional and xEV (EV, HEV, FCEV) vehicles.
• Can also be used in 48 V vehicle electrical systems.

Notes:

• Inductance measured between secondary pins at 100 kHz, 0.1 Vrms, 0 Adc.
• Primary current of 20 A causes less than 25°C temperature rise from 25°C ambient.Higher current causes a greater temperature rise (see Temperature Rise vs Current curve).
• Terminating resistance (RT) value is based on 1 Volt output with 20 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation: RT (Ohms) = Vout × Nsec / Iin.
• 500 Vrms, 1 minute isolation (hipot) winding to winding.
• Many differennt kinds of structure and style for your selection.
• Custom-made are welcome.

Notes: Product specifications can be customized
