Vishay Foil Resistors

Bulk Metal^®Z-Foil Technology Ultra High-Precision 4-Terminal

Power Current Sensing Resistors with TCR as Low as 0.05 ppm/°C,

Power up to 10 Watts and Thermal Stabilization of <1s

FEATURES

• Low temperature coefﬁcient of resistance (see ﬁgure 4):

• 0.05 ppmꢀ°C typical (0°C to +60°C)

• 0.2 ppmꢀ°C typical (–55°C to +125°C, +25°C ref.)

• Resistance range: 0R25 to 500R

• Resistance tolerance: to 0.01ꢁ

VFP4Z

VCS331Z

VCS332Z

• Power rating: 10W on heatsink(1) at +25°C;

3W in free air at +25°C (see Table 2)

• Load life stability:

•

0.005ꢁ (50 ppm) typical, 3W on heatsink at

+25°C, 2000h

0.01ꢁ (100 ppm) typical, 3W in free air at

+25°C, 2000h

0.01ꢁ typical (100 ppm), 10W on heatsink at

+25°C, 2000h

CSNG

• Vishay Foil Resistors are not restricted to standard

values; speciﬁc “as required” values can be supplied at

no extra cost or delivery (e.g. 1R2345 vs. 1R)

• Rapid ΔR stabilization under transient loads (see

Figure 2)

• Thermal resistance: 6°C/W

• Electrostatic discharge (ESD) at least to 25 kV

• Rise time: 1 ns, effectively no ringing

• Tenfold improvement of power coefﬁcient of

resistance (PCR): 4 ppm/W (see Figure 3)

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

• Thermal stabilization time <1s (nominal value achieved

within 10 ppm of steady state value)

• Voltage coefﬁcient: <0.1 ppmꢀV

• Current noise: 0.010 μV_RMSꢀV of applied voltage

(<–40 dB)

• Inductance: 0.1 μH maximum; 0.08 μH typical

• Thermal EMF: 0.1 μVꢀ°C (see Table 3)

• Non-inductive, non-capacitive design

• Pattern design minimizing hot spots

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).

(conceptual illustration)

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 ppmꢀ°C maximum (see page 5).
