The VCS1625P features a wide resistance range from 0.01 Ω to 10 Ω, with specific "as required" values within this range (e.g. 1.234 Ω vs. 1 Ω) available at no additional cost or delivery time. The resistor features a rise time of 1.0 ns, with effectively no ringing, short time overload of <0.005% (50 ppm), current noise of 0.010 µVrms/V of applied voltage (<-40 dB), and a voltage coefficient of <0.1 ppm/V.
The device withstands ESD to at least 25 kV, for increased reliability, and offers a non-inductive (<0.08 ?H), non-capacitive design. The VCS1625P is offered with tin/lead or lead (Pb)-free gold or tin termination options, and with additional temperature treatments (PMO) to extend the operating temperature from +150 °C to well above +200 °C. The design of the VCS1625P allows for designers to use only a single device to measure larger currents than previously possible by dissipating up to 1 W in the same 1625 size package.
The Bulk Metal Foil technology of the VCS1625P provides a reduction of the resistive component's sensitivity to ambient temperature variation (TCR) and to the self-heating effect caused by changing loads. These capabilities allow designers to guarantee a high degree of stability and accuracy in fixed-resistor applications. The resistor's load-life stability at +70 °C at rated power is an order of magnitude better than typical current sensing resistors (0.015% after 2,000 hours versus 0.05% after 1,000 hours).
The device's improved stability makes it suitable for tightened-stability reference voltage and precision current sensing applications in forced-balance electronic scales, measurement instrumentation, bridge networks, motor controllers and medical and test equipment. In addition, the VCS1625P can be tested in accordance with EEE-INST-002 (MIL-PRF 55342) for military and space applications.
