ISA-PLAN
ISA-PLAN
With ISA-PLAN® technology, the elements of a precision and power resistor are etched from the films of resistance alloys (MANGANIN®, ZERANIN®), which are electrically isolated and applied to a good heat-conducting metal substrate. The planar structures of the precision and power resistors and an optimized current density distribution allow for low-inductance designs and very low thermal internal resistance. An optimized current density distribution thus prevents the risk of hot spots.
The benefits of ISA-PLAN
Design
High continuous resilience with a small design
Values
Standard delivery of the strictest tolerances
High continuous
High continuous and pulse resistance
High stability
Very good long-term stability
Low values
Extremely low TK values
Low thermal stress
Thermal stress against copper is largely eliminated
How it works
After cleaning, marking and the fitting hole punching, the panels undergo a photolithography process where individual structures of the low-resistance resistors are already defined. The entire assembly in conjunction with the etching technology allows to produce an ideal four-wire SMD resistor in the low-resistance range.
