Fairchild Semiconductor reserves the right to make changes at any time without notice in order to improve design. If you’d like to buy new transistors, I’d look for something with a high gain bandwidth product.

Specifications may change in any manner without notice.

The schematic uses bf1999 BF transistor which is marked “obsolete” by datzsheet component suppliers. I tried to search at my preferred shop, https: Glenn W9IQ 14k 1 8 If you have some NPN transistors on hand, try those. Life support devices or systems are devices or systems which, a are intended for surgical implant into the body, or b support or sustain life, or c whose failure to perform when properly dafasheet in accordance with instructions for use provided in the labeling, can be reasonably expected to result in significant injury to the user.


Looks like a 2N will work. What would be a current and widely available equivalent? What are some equivalents of a BF transistor? Sign up using Facebook. Alexander Churanov 45 4.

A critical component is any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness.
