EMH2 / UMH2N / IMH2A
Transistors
General purpose (dual digital transistors)
EMH2 / UMH2N / IMH2A
!
Features
1) Two DTC144Es chips in a EMT or UMT or SMT
package.
2) Mounting possible with EMT3 or UMT3 or SMT3
automatic mounting machines.
3) Transistor elements are independent, eliminating
interference.
4) Mounting cost and area can be cut in half.
