Title: Innovations by Franciscus N Van Der Kruijs
Introduction
Franciscus N Van Der Kruijs is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of resistor technology, holding a total of 4 patents. His work primarily focuses on the development of advanced resistance pastes used in the manufacturing of resistor bodies.
Latest Patents
One of his latest patents is for a resistance paste designed for the manufacture of a resistor body. This paste is suitable for silk-screening applications and comprises a mixture of Pb₂RhₓRu₂₋ₓO₇₋ᵧ, along with a permanent binder and a temporary firable binder. The formula specifies that 0.15 ≤ x ≤ 0.95 and 0 ≤ y ≤ 1/2. The resulting resistor body demonstrates a temperature coefficient of resistance between -10 × 10⁻⁶ /°C and +10 × 10⁻⁶ /°C, maintaining stability across a temperature range from -55°C to +150°C. The resistance variation during the life of the resistor is remarkably small, less than ±0.5%.
Another significant patent involves a resistive paste for manufacturing a resistor body through screen-printing. This paste consists of a silver-palladium alloy and a metal oxidic compound that contains either PdO or can react with it, along with both permanent and temporary binders. The metal oxidic compound can be layered on the AgPd particles or mixed with them. This innovation results in a low-ohmic resistor with a temperature coefficient of resistance (TRC) of less than 100 × 10⁻⁶ /°C, effective in a temperature range from -60°C to +200°C.
