What are the advantages of MELF resistors?

MELF SMD resistors are the perfect choice for applications where reliability and stability are of major concern at higher power ratings and higher operating voltages.

Many electronic circuits are exposed to high pulse loads. This means that pulse-proof resistors are essential for protecting the circuit’s electronic components. These must be excellent in both pulse handling and long term stability, with low drift.

MELF SMD resistors offer a good solution. Although they are a thin film type, they are cylindrical rather than flat. This gives them a surface three times larger than a thin film resistor of the same size. This design also allows a helical trimming pattern to be used, enabling a uniform current distribution. Therefore, they can distribute heat more efficiently so their pulse load capability is five times higher, and their long term stability is excellent as well.

Apart from the standard metal film technology, MELF resistors are also available with carbon film, which has unrivalled thermal stability; this further enhances their pulse load capability.
