"Specification Details"
【model 】VPR221, VPR221S (a few other models are not marked)
The following resistance value table specifications are for reference. Resistances are often imported and shipped. For details, please confirm the specifications and quantities through Wangwang.
Example: 10Ω*7, 2K*3
The following product specifications are for reference:
0.25Ω, 0.5Ω,1Ω, 1.01Ω, 1.25Ω, 1.5Ω,2Ω, 2.25Ω, 3Ω, 3.3Ω, 4Ω, 4.7Ω, 6.18Ω,8Ω, 10Ω, 14.204Ω, 15Ω, 20Ω, 40Ω, 50Ω, 80Ω
100Ω, 101Ω, 118Ω, 150Ω, 250Ω, 500Ω,
The basic power is 1.5W and the heat dissipation can reach 8W. The resistance value is very suitable for transistor protection or frequency divider use!
Military products, seven specialties are tightened
Resistance<10Ω: BS accuracy is±0.1% The temperature coefficient is: 5PPM/℃
Resistance>10Ω: LS accuracy is±0.01% The temperature coefficient is: 5PPM/℃ A few resistance values: BS
Each has been tested for reliability and has an independent label. The test items are:
1: Initial appearance inspection 2 Room temperature test 3: High and low temperature cycle 4: Normal temperature re-test 5: Appearance review
Jining Zhenghe Electronics Co., Ltd. was established in 1999. It is a joint-stock enterprise established on the basis of the former state-owned Jining No. 3 Radio Component Factory. It is a designated backbone enterprise for military support specializing in the production of precision series resistors under the Ministry of Information Industry. It is the National Defense Science and Technology Commission. Audit confirmed“Weapon Equipment Research and Production Unit”, Verified by the Ministry of Information Industry as“Military electronic components scientific research and production enterprises”with“Qualified supplier of military electronic components”, The company was audited and assessed as“Level 2 Confidentiality Unit for Weaponry and Equipment Research and Production”.
The company’s products are widely used in key national defense projects such as aviation, aerospace, instrumentation, communications, electronic computers, and petroleum exploration, especially in“Shenzhou”Manned spacecraft and“Chang''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''e One”Played an important role in the supporting applications of the moon orbiting satellite!
Product Description:
This product is a new type of resistor produced by our company''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s introduction of the French production line, and is a recommended substitute for imported products determined by the original Ministry of Electrical and Mechanical Services. Because of its small size, high accuracy, low temperature coefficient, good stability, and high reliability, this product is widely used in inertial navigation power distribution control for aviation, aerospace, and navigation, various industrial instruments, and precision measurement systems for instruments. ,exist“Shenzhou”Manned spacecraft and other key engineering projects have played an important role. This product has been included in the "Military Resistor and Potentiometer Series Model Spectrum"( GJB/Z37.1-93), And was identified as a national key new product. According to the enterprise military standard, we can provide corresponding products of the same level.
