Positive Temperature Coefficient Thermistors TRIZ Cases
- Sol-Gel PTCR Resistor Composition for High-Temperature Self-Limiting Heating
A sol-gel PTCR thick-film resistor uses doped oxides and conductive nanowires to deliver lead-free, stable self-limiting heating at high temperatures.
- Sol-Gel PTCR Resistor Composition for High-Temperature Self-Limiting Heaters
A lead-free sol-gel PTCR paste uses doped semiconductors and reducing-atmosphere sintering to deliver stable high-temperature self-limiting heaters.
- PTC Composition Balancing Fast Heating and Current Limitation
A semi-crystalline PTC composition keeps resistance low for rapid heating, then rises sharply to limit current and prevent overheating.
- Modular Varistor Housing Structure for Overheating and Arcing
Segmented varistor elements in a conductive housing improve heat dissipation, prevent arcing, and maintain continuity under surge loads.
- Fluoropolymer Thick-Film PTC Resistor Composition for High Voltage Stability
A fluoropolymer and oxidized carbon black thick-film PTC composition improves resistivity stability and reliable cycling under high voltage.
- Dual-PTC Over-Current Protection with Insulated Via Structure
Dual PTC components linked by a conductive via and insulation layers create parallel protection paths that limit over-current damage and improve stability.
- Sol-Gel PTCR Thick-Film Resistor Coating for Self-Limiting Heaters
A lead-free sol-gel PTCR coating uses barium niobate and conductive nanowires to deliver stable self-limiting thick-film heating.
- PPTC Polymer Composition for Low Thermal Derating
A higher-melting polymer filler stabilizes PPTC resistance below trip temperature, reducing thermal derating and process jumps.
