Notes:
1. Output filtering capacitor C2 is an electrolytic capacitor, It is recommended to use high frequency and low impedance electrolytic capacitors. For capacitance and current
of capacitor please refer to manufacture’s datasheet. Voltage derating of capacitor should be 80% or above. C1 is used to filter high frequency noise. TVS is
recommended component to protect post-circuits (when converter fails).

All specifications measured at Ta=25C, humidity <75%, nominal input voltage, and rated output load, unless otherwise specified.
2008年7月9日, CombOLED 研究项目的工作重点是开发出高性价比的生产工艺，以实现有机发光二极管 (OLED) 的量产。欧司朗光电半导体公司固态照明部主管 Bernhard Stapp 表示：“该项目由欧盟提供资金支持，欧司朗负责协调运作，旨在为推行新型照明光源应用创造必要的条件。”这包括采用性价比卓越的方法构建新型元件架构，从而生产出大幅面透明光源。作为 LED 市场的创新推...[详细]
UHF和HF都是一般的技术分类，不过每一类都有独立的支持协议。HF在13.56MHz频段更具有一致性，虽然国际业内行业标准很多。UHF RFID在858-960MHz频段已商业化。同时也有多种国际标准支持，包括EPC global Gen 2。 标签与读写器通过无线链接交换数据。链接可以通过适合任何频段的、具有不同读取范围和抗干扰性的EMF或RF场实现。HF RFID技术主要通过电磁场传送信...[详细]
卡巴斯基的安全研究人员称其发现了如何攻击Intel微处理器的远程攻击代码，据传，这一代码可以通过TCP/IP包和JavaScript代码到达用户系统。 目前受影响的系统包括Windows XP，Vista，Windows Server 2003，Windows Server 2008，Linux甚至是BSD和Mac。但所幸大多数错误可以由Intel和BIOS厂商联合进行修复。 卡...[详细]
