Electronic systems are becoming smaller but are expected to deliver enhanced performance at the same time. The SC-55 series is a compact, high-performance SMD thick film chip resistor from Miba Resistors. It was developed to enable high electrical power in TO-263 footprint, while also delivering stable and reliable performance.
In this article, you will find important and relevant details about it.
The SC-55 series combines a power rating of 55 W and a TO-263 compatible footprint while exhibiting very low capacitance and inductance. It offers an efficient solution for applications where space is limited.
Optimized for high frequencies: Thanks to its very low capacitance and inductance, the SC-55 SMD chip resistor exhibits excellent high-frequency characteristics. This makes it ideal for fast switching operations and pulse-loaded applications.
Easy to integrate: Very low weight (<0.4gm) of SC-55 can replace D2PAK power resistors without changing the board layout.
Reliable under load: At the same time, it exhibits stable performance with high reliability, even at elevated temperatures and under continuous/pulsed load.
The new Miba Resistor SMD chip resistor demonstrates its strengths wherever a compact design is required:
The SC-55 is designed to integrate seamlessly into existing development environments as TO-263-compatible footprint allows it to be used as a drop-in replacement for existing D2PAK resistors without any layout modification. This saves time in the development process and reduces the effort required for design changes.
Compact design and low weight, the SC-55 SMD chip resistor is especially suitable for systems with limited space. Its high pulse load capacity also ensures stable results, even during fast switching operations and changing operating conditions.
The SC-55 is already available to customers in the US from DigiKey. This means that it will soon be available to developers worldwide for testing and production use.
