Surface-mount bulk metal Z-foil
resistors for AMS applications
Vishay Intertechnology announced that its new series of
wraparound surface-mount Bulk Metal Z Foil (BMZF) resistors
for avionics, military and space (AMS) applications is now
available with post-manufacturing screening (PMO) in accordance
with EEE-INST-002, DSCC, and EPPL. The new screening option
is available for devices in the 0805 through 2512 case sizes.
Some of the key features are:
1. Provide power ratings up to 750 mW at 70°C with
stability down to ±0.005%, typical TCR of ±0.2
ppm/°C, power coefficient of
resistance ("?R due to self heating") of ±5
ppm at rated power, and tight tolerance
of ±0.02%.
2. Available in any value from 10 O to 100 kO that can retains
its initial accuracy within several parts per million
3. Thermal EMF of less than 0.1 µV/°C
4. Voltage coefficient below 0.1 ppm/V
5. Inductance lower than 0.08 µH
6. Response time faster than 1 ns effectively no ringing
7. The noise generated by these resistors is less than -40
dB
8. ESD Immunity up to 25 kV,
9. Can withstand 100-Cycle thermal shock with a shift of
< 20 ppm and thermal stabilization Time of < 1 Second;
10. After 2,000 hours under full rated load at 70°C,
the resistance shift experienced by this SMD series is
just 0.005 % or more than an order of magnitude lower than
the typical 1.0% experienced by other
resistor technologies.
11. A conventional wrap-around termination and top coating
ensures safe handling during the mounting
process and provides stability during the multiple thermal
cyclings the device will experience
over its lifetime.
Availability: samples and production quantities of the
new wrap-around AMS resistors with post-manufacturing screening
are available now.
Package: Available in waffle-pack and tape-and-reel packaging
