Frequency Response Curve for TE2500 series wire-bound chassis-mount resistors

[gthpepl]

Hi! I’m interested in the impedance frequency response curves for the TE2500 series wire-bound chassis-mount resistors.

Would you happen to have data for this?

Hello, welcome to the Techforum! I have reached out to our product specialist to see if we can get this information for you.

Hello gthpepl,

Thank you for posting as it gave me an idea for a new forum post - link below. While I don’t have the TE2500 resistors in hand, I was able to demonstrate the frequency response using one of my junk box parts.

This little experiment suggests that wire wound resistors are acceptable for audio frequencies. They can also be used for higher frequencies, but we need to mitigate or at least make accommodations for the inductive reactance.

Please accept that article for what it is. It does not specifically address the TE2500 series of resistors which may or may not have the same properties as my old resistor.

Hopefully TE.com can give you a proper answer in the near future as requested via @Rob_Johnson.

Best Wishes,

Discover the Unexpected Frequency Response of Wire Wound Resistors

The textbook categorization of resistors, based on resistance, tolerance, and power rating, is incomplete. In this article we will demonstrate that real-world resistors have unexpected reactive attributes. This is especially true of wire wound types which exhibit both resistive and a significant inductive reactance at high frequencies.
