Foil Resistors Feature Long-Term Stability

VPG Foil Resistors’ SMR3Z1 molded surface-mount resistor with Z1 Foil Technology and flexible terminations meets all the criteria that define a precision resistor, including low temperature coefficient of resistance (TCR), long-term stability, low noise, low thermal electromotive force (EMF), and non-measurable voltage coefficient. The component enhances overall circuit stability and measurement functionalities.

 

The SMR3Z1 resistor’s low absolute temperature coefficient of resistance (TCR) reduces errors due to temperature gradients and it can withstand harsh environmental conditions. These characteristics make the resistor ideal for the high temperatures and radiation-rich environments found in down-hole exploration and well logging, and deep-sea under water repeaters in transoceanic communications. The molded package design and flexible terminations ensure minimal stress transference, addressing a concern in printed circuit board (PCB) applications where chips of 1206 and larger dimensions can delaminate or the PCB can develop cracks from thermal shock.
