DLW5BTM501SQ2L is a common mode filter manufactured by Murata. It has a light weight, compact size, and excellent electrical performance and stability, and is particularly suitable for use in communications, computers, and consumer electronics. This article will introduce this common mode filter in terms of structure, manufacturer, specifications and applications.
Common mode filter is a kind of electronic filter, mainly used to filter out the common mode interference signal in the signal. Common-mode interference signals are usually generated by common sources in power lines, ground wires, or other interconnected devices, and if not filtered out, may affect the normal operation of electronic circuits. In addition, common mode filters are used in data communications, high-speed digital signal processing, radio frequency signal identification and measurement, and other fields.
The DLW5BTM501SQ2L is a 2-wire common mode choke with surface mount design. With an impedance of 500 Ohms and an operating frequency of 100 MHz, this filter effectively suppresses common-mode noise and ensures pure signal transmission. With a rated current of 4A and a DC resistance (DCR) of 27 milliohms, it is capable of withstanding large current loads to ensure stable operation of equipment. It is mainly used in battery charging equipment, medical equipment and communication and electronic equipment.
