Vishay Foil Resistors
Bulk Metal
®
Foil Technology Power Current Sensing Resistors
with TCR of 5 ppm/°C and Power Rating up to 7 W
FEATURES
Temperature Coefficient of Resistance (TCR):
± 5 ppm/°C (Above 10
)
± 10 ppm/°C (Below 10
)
Tolerance: to ± 0.01 %
Resistance Range: 1
to 100 k
Electrostatic Discharge (ESD) above 25 000 V
Non Inductive, Non Capacitive Design
Rise Time: 1.0 ns without ringing
Current Noise: < - 40 dB
Any value available within resistance range
These Bulk Metal
®
Foil power current sensing resistors are
direct replacements for certain wirewound devices but
without the inductive characteristics of wirewounds. The
anodized aluminum housing is drilled and countersunk to
accept flat head screws for thermal mounting. Because the
device is internally Kelvin connected, there is no restriction
on the lead lengths as would be the case if this were a two
terminal device. Frequently used in YIG oscillator circuits
these devices contribute to superior frequency stability.
Thermal EMF: < 0.05 µV/°C typical
Voltage Coefficient: < 0.1 ppm/V
Non-Inductive: < 0.08 µH
Non Hot Spot Design
Terminal Finishes available: Lead (Pb)-free
Tin/lead alloy
Prototype Samples available from 48 h. Please contact
