When we use electricity to create danger, some fire-fighting equipment will sound an alarm to remind us to pay attention to circuit safety or to remind us to escape. Our customer has customized and produced four pin drum core inductors for use in fire protection equipment that boost or reduce circuit voltage. Together with other components, they can stabilize our circuit voltage and ensure our electrical safety.

The characteristics of four pin drum core inductor include：

/Small size, saving space for limited firefighting equipment and not occupying too much firefighting equipment space.

/High energy storage, although small in size, is different from its own volume. It has a large amount of energy storage, which can effectively provide energy for firefighting equipment.

/Having anti-interference function.

/In order to facilitate the differentiation of pin positions, long and short pin are often designed for easy PC board insertion. The inductance can be customized, and the turn ratio can be fixed, achieving the standard of lifting and lowering pressure.

/When the inductance is high, it is necessary to wind enough turns and the wire diameter is small. It is often fixed with glue at the tin point to protect the hanging point and prevent wire breakage.

/Protect with high-temperature resistant UL sleeves or PVC. Special pin design, less prone to open circuit and short circuit phenomena.
