Birox Resistor
« Back to Glossary Index
Definition:
A Birox resistor is a type of resistor made from a thick film of bismuth ruthenate that is fired with glass. These resistors are known for their stability and are used in various electronic applications.
Key Characteristics:
- Material Composition: Birox resistors are composed of bismuth ruthenate (Bi2Ru2O7) as the primary resistive material. This material is combined with a glass matrix during the manufacturing process.
- Thick Film Technology: The resistor is made using thick film technology, where the resistive material is printed or deposited onto a substrate and then fired to form a solid, stable film.
- Stability: Birox resistors are known for their excellent stability and reliability. They exhibit minimal changes in resistance over time and under varying environmental conditions, making them suitable for precision applications.
- Applications: Due to their stability, Birox resistors are often used in high-precision circuits, aerospace, military, and other demanding environments where consistent performance is crucial.
- Manufacturing Process: The process involves mixing bismuth ruthenate with glass, applying it to a substrate, and firing it at high temperatures to achieve the desired resistive properties.
Summary:
Birox resistors are precision resistors made from a thick film of bismuth ruthenate fired with glass. They are valued for their stability and reliability in various electronic applications, particularly where precise and consistent resistance is required.
