Miniature common-mode filters support automotive applications
Able to support high-speed differential transmission over 10Gbits per second and a maximum operating temperature of +125 degrees C, the KCZ1210DH series are common mode filters released by TDK.
The filters have a conductive resin-based electrode structure for high durability. They provide a noise control function for high-speed differential transmission signal lines for automobiles and is available in 1210 case size (1.25 x 1.0 x 0.5mm).
According to TDK, an increase in advanced driver assistance systems (ADAS) has led to rapidly growing demands for forward-sensing cameras and around-view monitors. Common-mode filters are used in vehicle camera signal lines in response to an increased volume of video signals.
The KCZ1210DH series supports high-speed signals with over 10Gbit per second transmission rates. The filers also contribute to noise control in the GHz band generated due to increased speed. By supporting an operating temperature range from -55 to +125 degrees C and adopting a conductive resin-based electrode, TDK said the filters control product cracks from thermal shock while increasing durability against mechanical stresses like substrate strains.
Outer dimensions of the KCZ1210DH120HRTD25 and the KCZ1210DH500HRTD25 are 1.25 x 1.0 x 0.5mm. The form factor saves board mounting space, added the company.
TDK is working on enhancing its inductive devices for ADAS and will expand its line of miniaturised common-mode filters, to support market demands for higher-speed differential signals.
The filters have a high speed interface (HDMI 1.4/2.0, LVDS/MIDI D-PHY, USB 3.0 / 3.1 Gen 1 and Gen 2.
The KCZ1210DH series of filers is in production now.
TDK was established in 1935 to commercialise ferrite, a key material in electronic and magnetic products. TDK’s innovation-driven portfolio features passive components such as ceramic, aluminium electrolytic and film capacitors, as well as magnetics, high-frequency, and piezo and protection devices. The product spectrum also includes sensors and sensor systems such as temperature and pressure, magnetic, and MEMS sensors. In addition, TDK provides power supplies and energy devices and magnetic heads. Products are marketed under the product brands TDK, EPCOS, InvenSense, Micronas, Tronics and TDK-Lambda.
TDK focuses on demanding markets in automotive, industrial and consumer electronics, and information and communication technology. The company has a network of design and manufacturing locations and sales offices in Asia, Europe, and in North and South America.
