Vishay launches Bulk Metal foil resistance
A few days ago, Vishay Intertechnology, Inc. announced that the sub-reference, sealed Bulk Metal® foil resistance - H and Hz series, set new industry benchmarks in precision, stability and speed. The new H and Hz series have a tolerance of 0.001% (10 ppm), 5Ω ~ 1.84mΩ resistance range, factory life stability in at least 6 years (not being treated) can reach 2 ppm (± 0.0002%), and the rise time is less than 1NS. The maximum TCR of the H series is ± 2 ppm / ° C, the maximum TCR of the Z-Foil Hz series is only ± 0.2 ppm / ° C.
Vishay's H and HZ products provide answers to those applications that have been implemented by excessive requirements, including resistance standards, feedback devices, precision divisors, measuring instrumentation expansion, precision bridges. Resistance and decimal voltage divider. Therefore, Vishay launched the device opened a lot of new design areas that never included in the scope of consideration.
In these two "H" product lines, the resistor element is mounted on the PCB plate fixed by the axis. The conductive connection between the resistance element and the lead is achieved by a special low stress structure. After loading the equipped component into the tinned brass housing, use a special process to discharge the water vapor in the package, then fill the oil, and seal it with the solder seal to achieve uniform heat, reduce the effect of extreme environments. The sealing joint causes water vapor and oxygen into the package, while the oil can function. By integrated use of these technologies and Bulk Metal foil technology, Vishay has created the most precise and stable "H" series resistance products.
Due to the extremely strict standards, in fact, these devices can be used as a set of deposits or periodic calibration of the factory test equipment. The accuracy of the H series device reaches the laboratory and metric level, and uses the additional internal guide process to increase long-term stability, such as chip stabilization, special TCR calibration, achieving additional processing of ultra high stability, and special post-manufacturing processing (PMO), such as temperature cycles, short-term overloading, and only accelerated load lifetime uses in Bulk Metal foil resistance.
The electrostatic discharge protection of the H series device is up to 25kV, the rise time is 1 ns, and there is no ringing, the current noise is less than -40dB, and the typical thermoelectric force is 0.05μV / ° C, the voltage coefficient is less than. 1881. 0.1 ppm / v. It is worth mentioning that Vishay's foil resistors are not limited to standard values, but they can provide specific values (such as 1.234kΩ vs. 1kΩ), and will not increase any cost or delivery time. The key technical indicators of the two H series devices are summarized in the table below:
