Transistors
High transition frequency (dual transistors)
EMX4 / UMX4N / IMX4
1) Two 2SC3837K chips in a EMT or UMT or SMT package.
2) High transition frequency. (f
3) Low output capacitance. (Cob=0.9pF)
Please consider to design ESD protection circuit.
∗1 120mW per element must not be exceeded.
∗2 200mW per element must not be exceeded.
This product might cause chip aging and breakdown under the large electrified environment.
