EMT1 / UMT1N / IMT1A
Transistors
General Purpose Transistor
(Isolated Dual Transistors)
EMT1 / UMT1N / IMT1A
Features
1) Two 2SA1037AK 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.
