High-Value Resistors for Mic Builders and Tempcos for Synths
Posted: Mon May 26, 2008 3:37 pm
I'm stocking a couple of hard-to-find resistors that some members here may eventually need.
For the mic builder I currently have a few 2G ohm (for the search engines who visit us 2000 Mohm). I'm almost sold out of these but I have a few 1Gohm on the way with more backordered. These are Vishay RNX0382G00KNLB (2G) and RNX0501G00FNEL (1G). They are 3/8W and 1/2W sizes. (Doubt we'll see that dissipation in a microphone though.)
The other one I stock is the Precision Resistor PT-146 (PT146). This is a 3500 ppm temperature compensating 1K 1% ideal for use in log and anitlog amplifiers. The 1K PT-146-1K and the 2K PT-146-2K (2K available from Music from Outer Space) are often use in DIY synth building. The 2K is a better choice if it's in the feedback loop of an op amp.
