  • Heat Sink Brochure-2-3

    Ohmite’s wide array of heatsinks are RoHS-compliant and available in multiple styles, sizes, and customization options. Download our brochure to explore product information and detailed specifications.

    • Dozens of heatsinks designed for TO-126, TO-218, TO-220, TO-247, and TO-264 packages
    • Thermal solutions for TO-252, TO-263, and TO-268 SMD devices
    • Product lines using a patent pending clip system that eliminates mounting hardware and speeds up installation times
    • Designs ranging from single device screw-mounted heatsinks to large custom extrusion profiles
  • Thermal Interface Material Role and Performance

    In many of today’s high-requirement and high-power electronic systems, traditional fans and bulky head sinks may not be enough to sufficiently deal with heat.

    Thermal interface materials (TIMs) bridge the gap between components and increase heat dissipation. This whitepaper provides an overview of TIM options and which will best serve your thermal management needs.

    This guide will detail:

    • Types of thermal interface materials
    • Why certain types are best for interfacing with
      heat sinks and enclosures
    • Assembly and reliability of thermal interface materials
    • Thermal pads for power products
  • EMI Filter Checklist

    Adding an EMI filter to your product will impact your product in several ways, beyond just attenuation.

    We break down the attributes to consider in How an EMI Filter Affects Your Product’s Performance.

    Learn how an EMI filter will affect the following and more:

    • Rated current and in-rush current

    • Rated frequency

    • Rated voltage

    • Voltage drop

    • Safety requirements

  • Ohmite EMI Filter Brochure

    Ohmite’s EMI filter families are designed for superior performance in a range of applications and available in multiple configurations to suit your project’s needs. Explore product information and specifications for these filter families:

    • AP Series, Single Phase
    • AF Series, Single Phase IEC Inlet
    • AG Series, Single Phase
    • AH Series, Single Phase Dual Stage
    • AHL Series, Single Phase Duel Stage Low Frequency
    • TG Series, Three Phase General Type
    • TK Series, Three Phase Bookshelf Type
  • Filter Location Can Affect Performance

    If your EMI filter isn’t performing optimally, the issue may not be the filter itself – it may be its location in the device. This whitepaper reviews how this happens and how to fix it.

    Topics include:

    • The difference between differential mode and common mode currents
    • How crossed-coupled energy happens and how it effects performance
    • Where to place a filter for peak performance
  • Contributing Factors of Filter Performance

    Many attributes of components themselves have a significant impact on filter performance – it’s important for designers to understand these and plan accordingly.

    This whitepaper reviews what to know about these factors and more:

    • Core material
    • Amount of windings
    • Wires in inductors
    • Leads in resistors
    • Parasitic aspects in capacitors
