Capacitors / Electric Double-Layer Capacitors (EDLC / Supercapacitors)
TDK has been offering pouch-type EDLCs, and has developed a new ultra-thin EDLC, with a thickness of 0.45mm (max.) that can be stored inside an IC card. It realizes battery-less smart cards equipped with a display, and is suitable for secondary power supplies for wearable devices or IoT devices.
Power Supply Inductor / In-vehicle inductor ADL3225V type
Along with the increasingly high speed and high functionality of in-vehicle LANs, in LVDS transmissions in-vehicle camera systems, PoC (Power over Coax) which placed signal and power source on top of each other in the single line are becoming increasingly advanced. Power inductor ADL3225V type guarantees transmission quality while saving space.
Common-mode Choke ACT45L type for automotive Ethernet
December 2018 : ACT45L-201-2P-TL000 listed on this page is a not-recommended for new design.
As sensor and camera based devices become more and more common in automobiles, Ethernet technology has been introduced at a rapid pace as automotive LAN systems for advanced multimedia and data communication devices. TDK developed the ACT45L type of common mode filters for Ethernet, which has achieved excellent noise suppression characteristics in a small and low-profile form.
With the increasing speed and sophistication of interfaces in cars, the PoC (Power over Coax) approach is gaining in popularity, as it allows superimposing signals and power in one coaxial cable, for example for LVDS based automotive camera systems. A PoC filter consisting of one or more inductors and chip beads is used on the circuit side to separate the signal and the power supply current. This is important in terms of maintaining communication quality. The PoC filter therefore requires inductors that realize high impedance for AC components over a wide bandwidth range from low to high frequencies.
The demand for high-speed automotive onboard interfaces is increasing, with a view towards supporting driving safety, reducing the environmental load, and improving comfort. For bidirectional communication, the automotive Ethernet format is commonly used, while LVDS is the choice for one-way communication. With LVDS (Low Voltage Differential Signaling), the preferred approach is to also adopt the PoC (Power over Coax) method that enables transmission of the signal and power supply over a single coaxial cable, thereby reducing the weight of wire harnesses in the car. This page describes usage examples and effects of inductors and chip beads specifically recommended for PoC filter applications.

We are transitioning from an age where people drive cars to an age where people provide mobility services and utilize autonomous driving capability. As a consequence, the number of electronic parts used in cars is steadily rising. If even a single component fails, a specific function may be impaired, which as a result, severe performance requirements are placed on the components reliability. TDK provides high frequency power inductors for automotive applications that are designed for outstanding reliability to reduce failure risks – HPL series, TFM series, and BCL series.
