Varistor Cores TRIZ Cases
- Modular Surge Arrester Isolation Before Short-Circuit Failure
A disconnect device isolates series MOV modules before short-circuit failure, containing arcing and reducing fire risk in surge arresters.
- Multilayer Varistor Electrode Layout for Low Crosstalk
Strategic internal and external electrode placement cuts stray capacitance and suppresses crosstalk in compact high-frequency varistors.
- Flexible Varistor Terminations for Bending and Thermal Stress
Compliant conductive polymer terminals help multilayer varistors resist bending and thermal cycling while maintaining surge protection.
- Flexible-Termination Varistor for Bending and Thermal Stress
Compliant conductive polymer terminals help multilayer ceramic varistors withstand bending and thermal cycles without losing surge protection.
- Laminated Varistor Electrode Layout for Stable Capacitance
A layered internal electrode layout reduces capacitance variation and crosstalk in laminated varistors for high-frequency use.
- Striped Internal Electrode Layout for Surge-Resistant Laminated Varistors
Segmented internal electrode strips spread surge heat in laminated varistors, limiting local hot spots without reducing active layers.
- Varistor Ceramic Composition for High Current Stability
Zinc oxide varistor ceramic with praseodymium dopants achieves improved nonlinearity while suppressing leakage current in high current ranges.
- Tubular Voltage Dependent Resistor with Inner Outer Electrodes
A tubular voltage dependent resistor uses inner and outer electrodes on a cylindrical chip to enable compact circuit integration.
- MOV-SCR Transient Overvoltage Protection Circuit
A series MOV and SCR circuit clamps transient overvoltages, minimizing leakage current while preventing load damage from excessive actuation voltage.
- Tin Oxide Ceramic Leakage Current Reduction via Boron Doping
Adding boron oxide to tin oxide varistors reduces leakage current by up to 90% while maintaining stability under thermal stress.
