Multi-layer varistor

**Tech Detail: Ultra-Thin ESD Varistor from TDK® CeraDiode™ Series** The new CeraDiode™ series of multilayer varistors from TDK®’s EPCOS brand represents a major breakthrough in ESD protection technology. These ultra-thin components are designed for use in mobile and high-speed electronic devices, offering unmatched performance in a compact form factor. Compared to traditional products, the size is reduced by up to 80%, with an insertion height of just 0.1mm. This makes them ideal for space-constrained applications like smartphones, tablets, and LED lighting systems. The series includes the smallest and most rugged varistors available, suitable for surface-mount packaging such as LGA (0.47mm x 0.47mm) and even smaller sizes like EIA 0402 and 0201. One of the standout features is their impressive ESD pulse absorption capacity, which is 50 times greater than conventional varistors. With ESD immunity reaching up to 25kV (depending on the model), these components meet or exceed industry standards for protecting sensitive integrated circuits. Their low clamping voltage—typically around 70V or 90V at 8kV—ensures signal integrity in high-speed interfaces like HDMI, making them a reliable choice for modern electronics. The CeraDiode™ series leverages advanced semiconductor materials and micro-core technology to deliver superior miniaturization without compromising performance. This innovation allows for direct integration into 3D circuits and modules, enhancing design flexibility. Additionally, the increased grain volume in the zinc oxide material significantly boosts the ability to absorb ESD pulses, providing enhanced reliability and durability. These varistors are not only smaller and more powerful but also cost-effective, making them a strong alternative to traditional TVS diodes. They are widely used in RF components of mobile communication devices and high-speed interfaces, where space and performance are critical. **Key Features & Benefits:** - Ultra-compact design (0.1mm height, 0.47mm x 0.47mm package) - Up to 25kV ESD immunity - Low clamping voltage (<100V @ 8kV) - Suitable for 0402, 0201, and smaller packages - Ideal for high-speed interfaces like HDMI - Enhanced ESD pulse absorption (50x improvement) **Applications:** - Smartphones and tablets - High-speed interfaces (HDMI, USB-C) - LED lighting systems - RF components in mobile devices With their combination of miniaturization, performance, and cost-effectiveness, the CeraDiode™ series sets a new standard for ESD protection in modern electronics. Whether you're designing next-generation mobile devices or high-performance computing systems, these varistors offer a reliable and efficient solution for your ESD protection needs.

Distribution Cabinet

The Main Distribution Frame is offered with compact size from 10pair (for 1 piece 10 pair disconnection krone module) to 2400 pair. For the installation, there are surface mount, floor standing, pole mount three ways for different application. Outdoor and indoor type is on option. Typically, the outdoor box is equipped with an airtight and watertight cover that allows for easy access to the interior components, making it easy to inspect and replace those components when and as necessary.

For different application and clients, we have the Main Distribution Frame made of ABS, PC, SML and CRC sheet with powder coating to match up with different requirements for indoor and outdoor installation. Besides, we have other MDF(Main Distribution Frame) made of stainless steel for 690pair/1200pair/ 1380pair and 2400pair.
