Space Saving Power Injection Inductors for Automotive — (PoC) As vehicles implement an ever-increasing amount of infotainment and safety systems, proportionate increases in wiring harnesses are required. In order to reduce the weight of these additional harnesses, engineers are looking at PoC to send both the power and data transmissions over the same cable. A bias tee is used on both the transmitter and receiver side to inject a DC power to an AC signal to power the camera module while also isolating the AC signal from the DC source to prevent signal distortion (see Figure 1). The proper selection of the inductor for PoC requires low insertion loss and high return loss over the entire frequency spectrum. Figure 1. Bias Tees in Power over Coax Applications Coilcraft offers a broad selection of PoC solutions providing significant reductions in board space while maintaining high return loss and low insertion loss over a wide frequency range. These solutions are all optimized for high-resolution and high-frame-rate cameras for existing and future Advanced Driver-Assistance Systems (ADAS). Coilcraft PoC solutions support current levels ranging from 300 mA to 1200 mA, covering popular SERDES application spectrums. Features Specific solutions for a variety of frequency spectrums and DC Current levels Low DC resistance All solutions have components qualified to AEC‑Q200 specifications IC Ref Design PFL1609-471 1205POC-222 SMD-POC-097 1.0 6000 0.56 2.7 16.88 0.9 0.87 0.85 Request a Sample Board or Custom Solution Interested in sampling our boards or you can’t find a solution here that fits your specific needs?
