PTC characteristic film heater with self-regulating function
Minco's SLT (Self-Limiting Technology) heater was developed as a replacement for traditional heaters and temperature controllers. It uses patented PTC characteristics with polymer materials, allowing it to meet various temperature control requirements without the need for temperature sensors or controllers. This simplifies system design and reduces manufacturing and operational costs. Heaters designed for each application adjust their output according to the usage environment, achieving self-temperature control. Unlike existing PTC heaters from other companies, its film-like structure provides flexibility and lightweight properties, avoiding constraints during application. The resistance of the polymer compound increases exponentially once the designed temperature is reached, automatically suppressing power. This eliminates the risk of overheating, making it suitable for environments where safety is a priority.

basic information
The SLT heater maintains the temperature of the heating target in a stable environment. It operates at high power during low temperatures, but as the temperature rises, the output gradually decreases, becoming nearly zero near the set temperature. The SLT heater has strong PTC (positive temperature coefficient) characteristics, allowing it to quickly reach a predetermined set temperature. Unlike other manufacturers' PTC ceramic heaters, it exhibits PTC characteristics across the entire temperature range from -100°C to the specified set temperature. Functions and Benefits: • It achieves high temperature uniformity and self-temperature control in a stable environment. • The patented material possesses PTC characteristics, simplifying system design and ensuring optimal performance. • Ambient temperature range: -45°C to 120°C • Operating set temperature range: 10°C to 70°C • No risk of overheating due to insulation material peeling or environmental changes • Thin, flexible, and lightweight

Company information
Minko has been providing thermal solutions since its establishment in Minneapolis, USA, in 1956. Initially, the company was engaged in the design and assembly of precision electrical equipment, but it expanded its range of in-house developed products starting with wire-wound temperature sensors, followed by flexible heaters and flexible printed circuit boards. Currently, it has evolved into providing heaters, sensors, flexible circuit boards, and integrated thermal solutions. Today, over 600 employees work at five locations in the USA, France, Japan, China, and Singapore, where local application engineers directly assist customers. Additionally, manufacturing is conducted at three locations in the USA, France, and China, allowing for production at the most suitable site based on specific projects, ensuring prompt delivery of products.
