Product may not be to scale

Rapid ΔR stabilization under transient loads, low wattage

coefficient (WCR), and low temperature coefficient (TCR)

are features of this new Z Based Bulk Metal^®Foil series of

Current Sense Resistors.

FEATURES

• Rapid ΔR Stabilization under transient loads (see Figure 1)

• Tenfold improvement of Wattage Coefficient of Resistance

(WCR): 4 ppm/W (see Figure 2)

The series should be selected where rapid .R 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

Based Technology provides extremely low WCR under

defined conditions (see Figure 1 and Figure 2). The low

absolute TCR provided by the Z Based Technology is

measured over the temperature range of - 55 °C to + 125 °C,

+ 25 °C reference (see Figure 3).

• Low Temperature Coefficient of Resistance:

(see Figure 3 and Table 2)

• Thermal Resistance: 6 °C/W

•

Power Rating: 10 watts on heat sink¹⁾at + 25 °C

(see Table 2)

3 watts in free air at + 25 °C (see Table 2)

All of these devices utilizing the Z Based Technology are

provided with a true 4 terminal Kelvin connection. This is a

must for current sensing when the R-value is less than

100 Ω. The VHP4Z and VPR247Z types add the additional

benefit of hermeticity. The welded construction and nitrogen

backfill provide maximum protection against environmental

stresses and insures long term stability. Typical applications

for this new series includes electron beam circuitry, electron

microscopes, fire control radar display systems, high speed

video display, deflection amplifier circuits, constant current

power supplies and forced balance electronic scales.

• Load Life Stability:

0.05 % Max ΔR, 10 W on heat sink at + 25 °C, 2000 hours

0.01 % Max ΔR, 3 W on heat sink at + 25 °C, 2000 hours

0.05 % Max ΔR, 3 W in free air at + 25 °C, 2000 hours

• Current Noise: < 0.01 µV(RMS)/volt of applied voltage

• Thermal EMF: 0.1 µV/°C maximum, 0.05 µV/°C typical

• Non-Inductive design

NOTE:

Custom high power designs can be developed for your

specific applications.
