| SFX Vishay Electro-Films Thin Film, Top-Contact Megohm Resistor CHIP RESISTORS FEATURES Product may not be to scale * Megohm resistance range: 1M to 20M * Chip size: 0.040 inches square The SFX series resistor chips extends the range of available resistance to 20 Meg. These offer one of the best combinations of small size and high value available. The SFXs are manufactured using Vishay Electro-Films (EFI) sophisticated thin film equipment and manufacturing technology. The SFXs are 100% electrically tested and visually inspected to MIL-STD-883. * Reduced hybrid size * Resistor material: tantalum nitride, self-passivating * Oxidized silicon substrate APPLICATIONS The SFX series megohm resistor chips are designed for use in hybrid packages which require small-size high-value resistors.
