Their product range includes power resistors, wirewound resistors, thick film resistors, current sensing resistors, and various types of electronic components designed for high-performance applications.

  • What are the key applications of Ohmite's resistors?

    Ohmite's resistors are used in a wide variety of applications including power electronics, industrial equipment, automotive systems, telecommunications, medical devices, and consumer electronics. Their products are designed to handle high power and ensure stability under demanding conditions.

  • What materials are used in Ohmite's resistors?

    Ohmite's resistors are made from various materials depending on the type and application. These materials include metal oxide, carbon film, wirewound elements, and ceramic substrates. Each material is chosen to meet specific requirements such as power handling, precision, and durability.

  • What is the difference between wirewound resistors and thick film resistors from Ohmite?

    Wirewound resistors from Ohmite are constructed by winding a resistive wire (usually metal or alloy) around a ceramic core. These resistors are known for their accuracy and ability to handle high power. Thick film resistors, on the other hand, use a resistive paste printed onto a ceramic substrate. While thick film resistors are more cost-effective and suitable for high-volume applications, wirewound resistors generally offer better precision and power dissipation capabilities.

  • What are current sensing resistors and how are they used in Ohmite products?

    Current sensing resistors are specialized resistors designed to measure current flow by detecting the voltage drop across the resistor. Ohmite’s current sensing resistors are commonly used in power supplies, battery management systems, automotive electronics, and energy monitoring devices. These resistors are characterized by low resistance values and high accuracy for current measurement.

  • What is the power rating of Ohmite's resistors?

    The power rating of Ohmite's resistors varies depending on the type and application. Ohmite offers resistors with power ratings from a fraction of a watt to several hundred watts. For example, their wirewound resistors can handle higher power ratings, making them suitable for power electronics and high-energy applications, while thick film resistors are typically used in lower-power applications.

  • Can Ohmite resistors be used in high-temperature environments?

    Yes, Ohmite offers a range of resistors that are specifically designed for high-temperature environments. Their wirewound and metal oxide resistors, in particular, are known for their ability to withstand extreme temperatures, making them suitable for use in industries such as automotive, aerospace, and industrial electronics.

  • What is the tolerance range of Ohmite's resistors?

    Ohmite's resistors are available in a variety of tolerances depending on the specific model. The tolerance typically ranges from ±1% to ±0.1%, and in some cases, precision resistors can offer tolerances as tight as ±0.05%. The specific tolerance is chosen based on the application's accuracy requirements.

  • Are Ohmite resistors RoHS compliant?

    Yes, many of Ohmite's resistor products are RoHS (Restriction of Hazardous Substances) compliant. This means they are free from certain hazardous materials, such as lead, mercury, and cadmium, and are designed to meet environmental standards set by the European Union for electronic components.

  • What is the voltage rating of Ohmite's resistors?

    The voltage rating of Ohmite's resistors varies by product type and application. Their resistors are designed to handle a wide range of voltages, from low-voltage applications in consumer electronics to high-voltage applications in industrial and automotive systems. It is essential to select the resistor with a voltage rating suitable for the specific application to prevent failure or damage.
