Whether you require a for a push-pull topology.

The C1124 is housed in a standard, through-hole plastic package—most commonly the TO-126 (also known as the Up-To-2 package variant by some Japanese manufacturers) or the slightly modified TO-92MOD depending on the specific suffix and production era. Its physical construction features a centrally located collector tab or lead designed to optimize heat dissipation to an external sink. Key Features
