Multi-layer varistor
Compared with traditional products, the size has been reduced by 80%, and the insertion height is only 0.1mm. This makes it ideal for space-constrained designs in modern electronics.
· The ESD pulse absorption capacity has increased by 50 times, offering superior protection against electrostatic discharge.
· It's the perfect replacement for traditional transient voltage suppression (TVS) diodes, especially in high-sensitivity applications.
Highlights of the 2014 Shanghai Electronics Show in Munich
TDK introduced the newly developed EPCOS CeraDiode series of multilayer varistors, including the smallest and most durable ultra-thin varistor available for ESD protection in mobile devices. This new range offers unmatched compactness, with a package size as small as 0.47mm x 0.47mm and a height reduction of just 0.1mm. It supports EIA 0402, 0201, and even smaller form factors, allowing for an 80% reduction in volume compared to conventional components. Despite its tiny size, it delivers extremely reliable ESD protection.
The CeraDiodes series features ESD immunity of up to 15kV or 25kV (depending on the model), meeting or exceeding industry standards for protecting sensitive integrated circuits. The clamping voltage is as low as 70V or 90V under an 8kV pulse (per IEC-61000-4-2), and its low capacitance ensures signal integrity in high-speed interfaces like HDMI.
TDK successfully combined advanced semiconductor materials with innovative micro-core technology to achieve a breakthrough in miniaturization of protective components. This technology allows the varistors to be directly integrated into 3D circuits and modules. Additionally, the new zinc oxide material increases grain density per unit volume, boosting ESD pulse absorption by 50 times. As a result, the CeraDiodes series offers three key advantages: miniaturization, enhanced performance, and cost efficiency. It is now the best alternative to TVS diodes.
The CeraDiodes series is primarily used in RF components of mobile communication devices and in high-speed interfaces such as HDMI.
Main Applications
· Smartphones, tablets, and LED lighting
Key Features and Benefits
· Available in 0402, 0201, and smaller sizes
· Insertion height as low as 0.1mm
· Up to 25kV ESD immunity
· Terminal voltage below 100V @ 8kV (per IEC-61000-4-2)
These compact and powerful varistors are changing the way engineers design for ESD protection. Whether you're working on next-generation mobile devices or high-speed data interfaces, the CeraDiodes series is a game-changer that combines performance, reliability, and space savings.
Fiber Optic Patch Panel(ODF)
Fiber optic patch panel is now widely used in networks and it is an integrated unit for fiber management, we are offering various kinds of Fiber Optic Patch Panel, such as wall mounted fiber optic patch panel, rack mounted fiber optic patch panels. These equipment functions to fix and manage the fiber optic cables inside the box as well as provide protection.
Our wall mounted fiber patch panels accommodate up to 8 modular panels and is equipped with routing guides to limit bend radius and enhance strain-relief control. The 16-gauge steel with corrosion-resistant black powder finish coat housing provides excellent protection for the inside fibers. Wall-mount available unloaded, as well as having the capability to become a full-splice enclosure with mechanical terminations. A large variety of connector adapters are offered to meet your specific requirements. Such as SC, FC, ST, LC, etc, we can also pre-install various kinds of fiber optic pigtails inside the patch panel.
YLTelecom offers a series of changeable inside panels to fit for different kinds of the adaptor interface, and fit for both round and ribbon fiber optic cables. Our rack mounted fiber patch panels can be drawer type or economic type without draw design.
A Fiber-Optic Patch Panel is used to separate out the fibers within a fiber-optic cable. By using one of these panels, the fibers can be spliced to individual fibers on other cables, allowing the cables to be crossed and connected in a variety of ways. In addition, the panel creates a safe environment in which to work with exposed fibers.
There are two main types of Fiber-Optic Enclosures. One is a wall-mounted device, which, in its most basic form, can keep 12 different fibers separate from one another. If the fiber-optic cable has more than 12 fibers, the extra fibers can be moved to a second panel or an engineer can use a panel that is designed to hold more fibers separately. Wall-mounted panels can be constructed to hold up to 144 fibers at once.
The other type of Fiber-Optic Patch Panel is a Rack-Mounted Panel. This type of panel holds the fibers horizontally and is often designed to open like a drawer. Sliding the panel open gives an optical engineer easy access to the fibers inside.
