Vishay released three new high-precision bulk metal foil resistors certified by CECC

April 30, 2009 - a few days ago, Vishay intertechnology, Inc. (NYSE Stock Code: VSH) announced the launch of three models for aviation A new type of high-precision bulk metal foil resistor certified by CECC for national defense and aerospace (AMS) - a batch of high-end scientific research achievements and patents rs92n, rs92na and an that can be directly printed and produced to automatic production equipment if the microcomputer function is strong. Under the reference temperature of -55 ℃ ~ +155 ℃ and +20 ℃, the typical TCR of the device is only ± 2ppm/℃, with a tolerance of ± 0.01%. The stability rate of load life after 2000 hours of operation at 70 ℃ is ± 0.005% (50ppm)

vishay's resistance launched this time can display the initial force to zero by simply adjusting the button. CECC certification (CECC standard certification is formulated for AMS applications that need long-term stability and high stability). Under the conditions of temperature change, loading, frequency 1 box of tofu 1 bag rate shift and short-term overload, the resistance value of the new resistance can be stably maintained at the initial value, This feature is unmatched by other products in the industry. In practical use, the change rate of these devices is only one millionth, while the change of thick film, thin film and winding resistance can be as high as several percentage points

in addition to the very low absolute TCR, strict tolerance and excellent load life stability rate, the thermoelectric electromotive force (EMF) of these devices released today is less than 0.1 μ V/℃, the voltage coefficient is less than 0.1ppm/v, and the current noise is less than -40db. The resistance range of an series is 80.6 Ω ~ 92k Ω, and the maximum resistance of rs92n and rs92na is 120K Ω. Vishay's foil resistance is not limited to products that provide standard resistance values. Vishay can provide products with "user required" resistance values (such as 90K Ω versus 90.123k Ω) without additional cost or delivery time

the power level of the resistance at +70 ℃ and +125 ℃ is 0.5W and 0.25W. The size of each device is 2.5mmx7.5mm, the height is 8.0mm, and the typical mass is 0.6g. The pin spacing of rs92na is 3.81mm, and the pin spacing of rs92n and an is 5.08mm

the new resistance has excellent resistance to ESD, and can withstand electrostatic discharge of 25kV at most, thus improving the reliability without inductance (0.08 μ H) And capacitive components. Other resistance technologies usually take a few seconds or minutes to achieve steady-state thermal stability, while rs92n, rs92na and an devices can achieve thermal stability almost immediately, taking less than 1 second, and the rise time of 1ns can hardly be measured, and will not cause ringing. These devices only provide tin lead alloy terminals

typical applications of resistors include DC-DC converters, feedback circuits, precision amplifiers in test and measurement instruments, medical systems, satellite and aerospace systems, commercial and military aviation equipment, weapon systems, and high-temperature systems such as drilling equipment. Prototype samples and batch orders of new devices are now available, and the delivery time is eight weeks
