2N3906 Matched Transistor Pairs
A number of the MFOS synth modules require matched transistor pairs such as the VCF. Read our article on how we match our transistors and for further reading, Ray Wilson's page on the MFOS site is very informative as well as providing construction details on how to build your own transistor matching devices. Whilst the recommendation is to match within +/- 2mV, we aim for better than +/- 1mV by not selecting pairs over +/- 0.7mV.

NPN Matched Transistor Pair Breakout Board (DMMT3904W)
A DMMT3904W matched NPN transistor pair ready mounted on a breakout board based on a DIP8 footprint. Supplied complete with a pair of female and a pair of male headers. Typically used for exponential conversion in VCO and VCF circuits to achieve a 1V/octave response. Pins 4 & 5 can be used for a tempco and with the male headers, it is breadboard friendly. Use the female headers on your PCB as an IC socket. Pin compatible with the SSM2210 & LM394 and our MFOS VCO. Specification PCB Size: 11.5 x 11.5mm hFE Matching: 2% max, typically 1% VBE Matching 2mV max, typically 1mV VCBO: 60V max VCEO: 40V max VEBO 6V max PD: 200mW IC: 200mA RoHS Compliant For more electrical information, see the DMMT3904W datasheet
