Frequently Asked Questions
Q: What does "non-inductive" mean for the RI80 glass glaze film resistor?
A: A non-inductive resistor is wound or constructed in a way that cancels out any inductance. This is critical in high-frequency, pulse, or RF circuits where even small inductance values could cause signal distortion or energy losses. The RI80 non-inductive design ensures purely resistive behavior across a wide frequency range.
Q: What resistance values are available for the RI80 20W and 50W resistors?
A: The RI80 series covers a broad resistance range including 1KΩ, 20KΩ, 50KΩ, 300KΩ, 30MΩ, 200MΩ, and 500MΩ, among others. This wide selection makes the RI80 suitable for everything from moderate voltage division to ultra-high-voltage measurement applications.
Q: Is the RI80 glass glaze resistor suitable for outdoor or harsh environments?
A: The glass glaze film coating provides a high degree of environmental protection against moisture, dust, and temperature fluctuations, making the RI80 a reliable choice for both indoor industrial equipment and applications exposed to varying environmental conditions. Always verify the specific operating temperature range for your selected resistance value and power rating.
Q: What is the difference between the 20W and 50W versions of the RI80?
A: The power rating (20W vs. 50W) indicates how much electrical power the resistor can continuously dissipate as heat without damage. The 50W version is physically larger and better suited for higher-current or higher-power applications, while the 20W version is more compact for space-constrained designs.
