Common mode choke satisfies 1000BASE-T1 automotive LAN
Claimed to be the first common mode choke designed to be compatible with 1000BASE-T1, the automotive, 1Gbits per second LAN standard, the DLW32MH101XT2 is being sampled now by Murata.
It is, says the company, the industry’s smallest common mode choke coil for 1000BASE-T1 applications.
Vehicle communications buses are expected to carry increased bandwidth data from high resolution image sensors and complex electronic control units (ECUs) as aclude advanced driver assistance systems (ADAS) and in-vehicle infotainment (IVI) is adopted, in a move to vehicles’ autonomous operation, hence the introduction of 100BASE-T1.
The DLW32MH101XT2 supports the S-parameter characteristics specified by the Open alliance automotive network standard organisation and meets the characteristics for noise filters in 1000BASE-T1 communications. Murata’s winding technology contributes to the small size of just 3.2 x 2.5 x 2.5mm and weight of 0.064 g. Its inductance value is 100 microH and typical DC resistance is 2.6 Ohm, and it is rated for currents up to 100mA.
The choke coil complies with the AEC-Q200 automotive standard and operates at the extended temperature range of -40 to +125 degrees C.
Murata manufactures electronic components, modules, and devices, including ceramic capacitors, resistors and thermistors, inductors and chokes, timing devices, buzzers, sensors and EMI suppression filters. In addition to ceramic capacitor manufacture, it also supplies Bluetooth and WiFi modules, board-mount DC/DC converters and standard and custom AC/DC power supplies.
