1) _{Load acc. To DIN 45921 on PCB. limited by temperature of solder area (competitor data often too high)}
With suitable heat dissipation higher power rating is possible.
Diagrams for over temperatures available on request.
2) _{TC/50: Temperature range + 25°C...+ 125°C}
Zero-Ohm-Jumper: :< 50 mOhm. TCR max. + 4000
M at 2512/4020: Meander structure with higher working voltage in bracket.
Higher power dissipation, other sizes and specifications on request.
