P-QJ201 Transistor - JFET, N-Channel, MMBFJ201, SOT-23
Surface mount MMBFJ201 JFET. Commonly used in place of the discontinued through-hole J201. These JFETs can be found in many effects pedals, synthesizers, and other projects. The MMBFJ201 is an N-Channel general purpose amplifier JFET. This device is designed primarily for low level audio and general purpose applications with high impedance signal sources.
$0.45
P-Q2N3904 Transistor - 2N3904, TO-92 case, NPN
General purpose low-power NPN bipolar junction transistor, used frequently in hobbyist electronic projects.
$0.18
P-QTL072 Op-Amp - TL072, Dual, Low-Noise, JFET Input, 8-Pin DIP
The TL072 is a high speed JFET input dual operational amplifier incorporating well matched, high voltage JFET and bipolar transistors in a monolithic integrated circuit. The device features high slew rates, low input bias and offset current, and low offset voltage temperature coefficient.
$0.70
C-ETRX-25 Capacitor - 25V, Radial Lead, Electrolytic
Package of 5
High quality, radial leaded, aluminum electrolytic capacitors rated at 25VDC.
Starting at $0.49
P-QFV-1 Integrated Circuit - Spin FV-1, DSP, Multi-Effect / Reverb
The Spin Semiconductor FV-1 is a complete reverb solution in a single IC. With integrated stereo ADC and DACs, the FV-1 can be treated like any other analog component in your product's signal path. The FV-1 can access a total of 16 programs, 8 are built into the internal ROM and the designer may elect to connect a serial EEPROM with 8 additional programs. By using an external EEPROM, the designer can distinguish his product from others by creating a custom program set without the need for a microprocessor in the system. With 3 potentiometer inputs, programs may have real time variable parameters such as decay time in a reverb, rate and depth in a chorus or frequency in a filter. These inputs are available as coefficients to your program and may be used independently of each other. The rich instruction set allows users to program effects of all kinds. With instructions like LOG and EXP, users can easily program audio expansion and compression routines.
