TMR
Vishay Electro-Films
Thin Film Tapped Microwave Resistor
FEATURES
Product may
not be to scale
• Wire bondable
• Six resistors on a single chip: size 0.020 x 0.060 inches
• Resistance range: 10 Ω Sto 240 Ω
• Alumina substrate
The TMR resistor chips on alumina are designed with
multiple low ohm taps for circuit trimming. The resistor
geometries are compatible with strip lines, making them
ideally suited for microwave circuits.
• Low stray capacitance: < 0.2 pF
• Resistor material: Tantalum nitride self passivating
• High frequency
These chips are manufactured using Vishay Electro-Films
(EFI) sophisticated Thin Film equipment and manufacturing
technology. The TMRs are 100 % electrically tested and
visually inspected to MIL-STD-883.
APPLICATIONS
Vishay EFI TMR chip resistors provide excellent high frequency response and are ideally suited for prototyping.
Typical application areas are:
• Amplifiers
• Oscillators
• Attenuators
• Couplers
• Filters
• Limiters
