The integrity Electronics Co., Ltd. is a professional production of diode manufacturers, the products are mainly IN400 series, IN539 series, 6A series, FR, HERIA, 1.5A, 3A, 6A series and Schottky diode IN581, IN582 series, glass diodes IN4148, regulator of the series, DB3 trigger pipe and other products, dozens of varieties, products mainly to the domestic, but also exported to Hong Kong, the new plus Singapore, South Korea and other places, widely used in electronic equipment, instrumentation, mobile communication and aerospace and other high-tech fields. Jincheng letter galvanized Ltd. in east China is small pieces of hot-dip galvanizing industry leader, the company more than a decade working on galvanizing quality, innovation, has obtained two national patents, patent number: ZL93232437. 1 and ZL01277708.0 years, the company has always adhere to the "quality of survival, to the credibility of development. honesty, sharing of resources," the operating principles, Shanghai rectifier diode, to provide customers with quality products and quality services, while constantly innovation, development, based on high-tech product development and production, Zhejiang rectifier diode, and continue to expand production scale and investment in new products, the company continued to develop and grow steadily. Rectifier diode inspection methods first rectifier diode rectifier all removed, with multimeter 100 × R or 1000 × R ohm measurement of two rectifier diode lead (head, tail reversed each test once). If the resistance values ??of the two measured vary widely, such as a large resistance value of up to several hundred KΩ to infinity, and the resistance value is small only a few hundred Ω even smaller, indicating that the diode is good (soft breakdown occurs except diode). If the resistance values ??of the two measured almost equal, rectifier diodes, and resistance value is very small, indicating that the diode breakdown has been damaged and can not be used. If the two measurements of the resistance are infinite, the description for this diode has been disconnected internally can not be used. Most of the full-bridge rectifier to detect the entire bridge, are marked with "+", "-", "~" symbol (where "+" is the positive output voltage is rectified, "-" for the output voltage of the negative, " ~ "AC voltage input), it is easy to determine the respective electrodes. Rac electronic information network detection, it may separately measure the "+" and the two "-" pole, the two "-" pole and the "-" positive and negative resistance value between each pole of the rectifier diode (ordinary diode The same measurement method) is normal, Wuxi rectifier diode, to determine whether the whole bridge has been damaged. If the measured bridge across the four positive and negative resistance values ??are 0 or diodes are infinite, you can determine that the diode breakdown or open circuit damage. Detection of the half-bridge is composed of two half-bridge rectifier diodes, were measured by using a multimeter positive and negative resistance values ??of the two diodes inside the half-bridge is normal, it can determine the half-bridge is normal. Shanghai rectifier diodes, gold credit (certified), rectifier diode provided by Qingdao integrity Technology Co., Ltd. Qingdao integrity Technology Co., Ltd. (www.qdjcx.com) is in Qingdao, Shandong diode leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
