TOSHIBA TRANSISTOR 2-4E1A -50V -.15A .2W ECB Transistor, Type: SI-P, Voltage: 50 V, Current: 0.15 A, Power: 0.2 W, Frequency: 80 MHz
It would be nice if MCM listed the full part model. It's important when matching for my headphone amplifier. Toshiba's sound very nice and clean when used in an amplifier. I highly recommend them as a matched NPN+PNP pair (check the data sheet for the compliment's model number).
This is a 2sa1048gr (at least as it was shipped in July 2011). Beta was measured 230-250 on my 6 ordered. The rest can be gathered from the data sheet. Note that these are low capacitance and low noise transistors.
