CTM
Vishay Electro-Films
Megohm Center-Tap Chip Resistor
FEATURES
• Wire bondable
Product may not
be to scale
• Resistance range total: 200 kΩ to 10 MΩ
• Center tap
• Chip size: 0.040 inches square
• Resistor material: Tantalum nitride, self-passivating
• Moisture resistant
The CTM resistor chips extends the resistance range to 10M
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.
APPLICATIONS
Vishay EFI CTM tapped megohm resistor chips are designed for hybrid packages requiring high value, two resistor combinations.
