1. Contact rating - Product of the switching voltage and current should never exceed the wattage rating. Contact Littelfuse for additional load/life information.
2. When switching inductive and/or capacitive loads, the effects of transient voltages and/or currents should be considered. Refer to Application Notes AN108A and AN107 for details.
3. Breakdown Voltage - per MIL-STD-202, Method 301.
4. Electrical Load Life Expectancy - Contact Littelfuse with voltage, current values along with type of load.
5. This resistance value is for 11.81mm wire length. Resistance changes when wire lengthens.
6. Operate (including bounce)/Release Time - per EIA/NARM RS-421-A, diode suppressed coil (Coil II).
7. Shock and Vibration - per EIA/NARM RS-421-A and MIL-STD-202.
8. For custom modifications to the wire length or size, or adding a special connector, please contact Littelfuse.

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]
中风发生时，一切都是以秒来计算的。延误治疗可能导致大脑重大损伤。伦敦大学医学院的一位博士Alistair McEwan已经获得行为医学研究所(Action Medical Research)的同意，为急救人员开发一种无线诊断系统来减少时间延误。感谢抗血栓药物，一些病人在病情发作的三个小时之内可以完全恢复。但出血也会导致中风。医生在治疗之前需要确定发病原因，因为不适当的服用抗血栓药物会加重损害。...[详细]
