Kaschke Component - Can't Find Datasheet or Equivalent?

[CShar.3]

Hi everyone,

I have a power supply I'm trying to repair and have removed a Kaschke component that I'm unable to find a datasheet for.

Is anyone familiar with with manufacturer that can help me identify this component?

"KASCHKE 044.129"

Well this is an ST (SGS-Thomson) forum.

What type of device?

What package style?

How many pins?

Any understanding how any of those pins function in the original circuit?

Perhaps a couple clear, large and in-focus pictures of said part, in context..

Details of the make/model of power supply?

Thanks for you response!

I don't have some of the info with me that you've requested, but I have a few pictures that are hopefully helpful to you.

I believe it is some type of inductor - it has 4 pins. I'm not sure what exactly it's purpose is in the circuit.

The power supply is out of an automated light fixture (entertainment industry).

Common Mode Toroid Choke, perhaps custom, you'd likely need to measure one not blown up.

The off-the shelf ones have details, typically current/voltage

It's some filtering choke, which will almost never fail. Why did you even solder ir out? It can be checked with multimeter inside the circuit in like 6 seconds. A "repair" by randomly soldering out some components rarely leads to success. And, if the power supply is of SMPS type, then the hope of fixing the power supply by replacing some single passive component without understanding how the power supply works, is naive. Apart from aged electrolytic capacitors, almost always the source of the trouble is some damaged semiconductor and then possibly other components as a consequence.

Thanks for your response!

A few things - I am new to electronics repair, so yes, some of the things I'm doing can be considered naive. However, I believe some are justified as well.

I'm not familiar with filtering chokes so that is something I'll need to study up on.

The power supply failed due to a lamp lead being shorted to ground. A fuse blew and this component "appeared" damaged. However, due to the design of the board I was unable to see the writing on this component to identify it. Also, there are some traces underneath this component the needed attention, but there was no way to access them without removing it. So in order to identify the component and access the traces underneath I had to remove the component.
