VPG Foil Resistors

SMR1DZ/SMR3DZ Z-Foil Molded SMD Resistors

VPG Foil Resistors ultra-high precision molded chip resistors feature Z-Foil technology for ultimate thermal stability

Image of VPG Foil Resistors SMR1DZ / SMR3DZ Z-Foil Molded SMD ResistorsVPG Foil Resistors SMR1DZ and SMR3DZ series are molded, surface-mount resistors based on Z-Foil technology, offering unmatched thermal stability and exceptional load-life performance. Designed for use in demanding analog applications, these resistors deliver a typical TCR of ±0.2 ppm/°C typical, load-life stability of ±0.005%, and a PCR of only 5 ppm at rated power.

Equipped with flexible terminations to reduce PCB stress and improve long-term performance, the SMR1DZ and SMR3DZ are ideal for high-precision environments such as metrology, medical instrumentation, and aerospace electronics.
