INTRODUCTION
The most precise measuring of electrical current is
achieved by the current sensing resistor method. The
precision and speed of response to changing current
depend on thermal stability of the resistor, as determined
by its low temperature coefficient of resistance (TCR) and
related power coefficient of resistance (PCR), as well as
its net reactance.
VCS331Z, VCS332Z, and VFP4Z (0R25 to 500R)
This series should be selected where rapid ΔR
stabilization and resistance stability under transient power
conditions is required. These products achieve optimum
performance when mounted on a chassis or cooled heat
sink. The Z-Foil technology provides extremely low PCR
under defined conditions (see Figure 2 and Figure 3). The
low absolute TCR provided by the Z-Foil technology is
measured over the temperature range of –55°C to +125°C
or 0°C to +60°C, +25°C reference (see Figure 4).
All of these devices utilizing the Z-Foil technology are
provided with a true 4-terminal Kelvin connection. This is
a must for precise current sensing when the resistance
value is less than 100Ω (see Figure 6).
CSNG — New Generation of
Power Current Sense Resistors (>0R005)
Custom high power designs can be developed for your
specific applications. Vishay Foil Resistors (VFR) recently
introduced New Generation of Power Current Sense
Resistors (CSNG) with short thermal setting time, long-
term stability, high power to 20W and absolute TCR to
±0.5 ppm/°C maximum (see page 5).
