The C945 is an age old Japanese Bipolar audio frequency NPN transistor 60V 150mA TO-92 package. It has a decent gain value (hfe) of maximum 700 and is highly linear. Hence it was widely used in amplifier.
These epitaxial planar transistors are mounted in the TO-126 plastic package. The NPN types are the BD135 and BD139, and the complementary PNP types are the BD136 and BD140.
The 2SD2196 200V 15A 65W NPN Darlington Transistors TO-3P Plastic Package. This is a Through Hole Maximum Operating Temperature: + 150C Continuous Collector Current: 15A DC Collector/Base Gain hfe Min: 1500 Height: 13.5 mm Length 15 mm.
The IRF830PBF is a 500V 4.5A 100W TO-220AB Package Third generation power MOSFETs from Vishay provide the designer with the best combination of fast switching, low on-resistance and cost-effectiveness.
The Hall Effect Sensor Module can be used to detect the presence of an magnetic field. If there is an magnetic field present, it will report a high level signal.
The CD4026B- and CD4033B-series types are supplied in 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (NSR suffix), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).
