[TCML] Terry Filter Resistors

[bartb]

Simon,

The manufacturer PN is LTO100F1K and is a TO-247 package. In free air by 
itself it's rated at 3.5W. If sinked well (big with external cooling), 
it is claimed to handle 100W. That may be more trouble than it's worth 
and more expensive than using a standard ceramic power resistor.

If it were not for the cost and complexity, you could go with this type 
of package minus forced air cooling by putting say ten 1000 ohm 
resistors in parallel on a heatsink (100 ohm total). The current through 
each resistor would branch at 1/10 current per resistor. But due to the 
cost and complexity, not a good solution. The standard power resistor is 
the way to go.

Anyway, here's the datasheet.

Take care,
Bart
