Malvern, Pennsylvania-(

)-VPG foil resistors (product group of Vishay Precision Group, Inc. (NYSE: VPG)) and the industry's most precise and stable precision resistor manufacturer, today announced a new ultra-high precision Vishay foil resistor molding Surface mount resistors using Z1 foil technology and flexible terminals. SMR3Z1 resistors meet all the criteria that define precision resistors, including low temperature coefficient of resistance (TCR), long-term stability, low noise, low thermal electromotive force (EMF) and unmeasurable voltage coefficient. This product enhances the stability and measurement function of the overall circuit.

The low absolute temperature coefficient of resistance (TCR) of the SMR3Z1 resistor reduces errors caused by temperature gradients and can withstand harsh environmental conditions. These characteristics make the resistor very suitable for the high temperature and radiation-rich environment found in deep sea transponders in downhole exploration and logging and transoceanic communications. Molded package design and flexible termination ensure minimal stress transfer, solving a problem in printed circuit board (PCB) applications where 1206 and larger chips may be delamination or PCB may be affected by thermal shock Cracks occur.

SMR3Z1 resistors are also ideal for precision amplifiers, differential amplifiers, pulse applications, control systems and power applications, especially in the medical, industrial, audio, low frequency, military, aviation and space exploration industries.

Vishay foil resistors SMR3Z1 resistors are based on the latest generation of bulk metal Z1 foil technology

Aluminum foil technology. The equipment using Z1 foil technology is superior to all previous stability standards for precision resistors, greatly improving environmental stability. They are actually insensitive to unstable factors. These unique characteristics are achieved through the use of solid alloys that match the ceramic matrix bonded with polyimide, so that the thickness of the bonding line is uniform, with excellent bonding strength and improved moisture resistance.

Precision resistors made of bulk metal

Foil technology provides extremely low temperature coefficient of resistance (TCR) and excellent long-term stability even at extreme temperatures. Vishay foil resistor devices provide a wide range of resistance values, and can be produced with any tolerance under any resistance value within a given range without incurring additional cost or delivery time impact.
