Murata’s latest EMI filter coil

The popularity and ubiquity of HDMI in A/V equipment, particularly TVs, is driving developments in EMI filter technology. The new EMIFIL coil uses a combination of Murata’s proprietary ceramic materials, inner electrode design and process technologies to deliver impeccable signal integrity with line impedance matching (100 ohms), as well as the required high cut-off frequency.

The DLP11SA101SL2 weighs just 0.005g and has a 100M ohm insulation resistance, a rated voltage of 5Vdc and a withstand voltage of 12.5Vdc. The coil’s operational temperature is -40 to 85 degrees (C).
