Frequently Asked Questions
Is this product safe to handle?
It contains beryllium oxide, which is safe only if the BeO disc remains undamaged. Dispose of it as chemical or special waste.
What are the primary applications for the BFQ135 transistor?
It is suitable for MATV and microwave amplifiers, radar, emitter systems, oscilloscopes, and spectrum analyzers.
What is the maximum total power dissipation (Ptot)?
The maximum specified total power dissipation (Ptd) under these conditions is 2.7 W.
If I exceed the absolute maximum ratings, what are the risks?
Refer to the Absolute Maximum Rating System for limiting values; exceeding these limits compromises product safety and reliability.
