| CTM Vishay Electro-Films Megohm Center-Tap Chip Resistor CHIP RESISTORS FEATURES Product may not be to scale * Resistance range total: 200k to 10M * Center Tap The CTM resistor chips extends the resistance range to 10Meg in a center tap configuration while keeping the die size relatively small. The CTMs are manufactured using Vishay Electro-Films (EFI) sophisticated thin film equipment and manufacturing technology. The CTMs are 100% electrically tested and visually inspected to MIL-STD-883. * Chip size: 0.040 inches square * Resistor material: tantalum nitride, self-passivating * Moisture resistant APPLICATIONS Vishay EFI CTM tapped megohm resistor chips are designed for hybrid packages requiring high value, two resistor combinations.
