Richardson RFPD’ Thick Film Resistor offering from Ohmite can range from precision surface-mount components, like the Macrochip Series (MC), to medium power (12.5W) Maxi-Mox Series axial leaded resistors, and large, 600W - 1000W heat-sinkable planar power resistors (like the TAP600 and TAP1000 Series).
Applications for Thick Film Resistors include power supplies, snubber circuits, inverters (resistor banks), voltage regulation, low-energy pulse loading, frequency conversion circuits, and as a “bleeder resistor.” Thick Film Resistors can have either a small or a large Temperature Coefficient of Resistance (TCR). They are also available in many tolerances and power levels. Richardson RFPD provides design support to help engineers select the best Thick Film Resistor for the specific application.
Specific attributes which are important in selecting the right Thick Film Resistor for your application include: Package Type – usually Axial, Planar-Heat Sinkable, or SMD; Maximum Voltage Rating (V); Power Rating (W); Resistance (Ω); Tolerance (%); Operating Temperature Range (⁰C); Temperature Coefficient (ppm/⁰C); and the part’s Dimensions (mm).
The parametric search filter allows the user to quickly find the parts they need by filtering the results in real-time.
Additionally, some attributes allow for the conversion of their base type to different types. For example, the attribute group for minimum frequency is shown in MHz. The values can be converted to be shown in KHz or GHz by selecting the conversion type from the ‘Select Conversion’ drop down list.
Any Attribute that does not interest the user can be hidden by clicking on the ‘X” in the upper-right corner of the attribute. To show any hidden attributes, simply click the ‘Unhide Attributes’ button in the bottom of the parametric search filter.
If you are experiencing performance issues, please use a newer browser such as Chrome or Firefox, or disable the ability of the filter to perform dynamic updates by deselecting the checkbox titled ‘Allow Filters to Dynamically Update Parametric Search Attributes’.
