Vishay demonstrating its latest
resistor's benefits through an online video
Vishay is displaying the benefits of its latest metal foil
resistors through a streaming video available on its website.
Vishay says, its bulk metal foil resistors are designed
and manufactured to eliminate the inter-parameter compromise
inherent in all other types of precision resistors. All-important
characteristics - tolerance, long-term and load-life stability,
temperature coefficient, noise, capacitance, inductance,
and rise time - are optimum, approaching in total performance
the theoretical idea of a straight wire of constant electrical
The video feature an accelerated life test and highlight
the TCR performance of Bulk Metal Foil devices and the in-circuit
performance of Vishay Bulk Metal Foil resistors when subjected
to ESD, a major cause of component failure.
The video is available at:
Vishay has also announced a new component sourcing service
called "Panic Button" service, to provide prototypes
of bulk metal foil resistors in five working days or less.
Through Vishay's "Panic Button" services circuit
designers only need to provide overall electrical performance
specifications, the environmental operating conditions,
and the desired physical requirements. Vishay will then
select and package the bulk metal foil resistor or resistors
in the most suitable combination to meet performance requirements
Vishay claims, bulk metal foil devices have an almost instantaneous
thermal stabilization time of < 1 second, and a nearly
immeasurable 1.0-ns rise time, effectively without ringing.
