Thin Film vs Bulk Metal Foil Resistor Network TCR Comparison

Video from VPG Foil Resistors is demonstrating comparison of resistor to resistor TCR tracking performance of a 16 pin DIP thin film and Bulk Metal Foil resistor network — Resistor to resistor TCR matching and tracking performance is a critical consideration for ultra-precision amplifier and bridge circuits. As shown in this demo, Bulk Metal® Foil resistor networks are more than 10 times more accurate than thin film equivalents.
