They are the perfect choice in high frequency circuit designs where the parasitic inductance of regular, helical trimmed resistors can not be accepted, but where also pulse energies apply. Typical applications are in the fields of telecommunication equipment and industrial electronics. • Compliant to RoHS directive 2011/65/EU APPLICATIONS • Telecommunication equipment • Industrial electronics METRIC SIZE DIN 0204 CECC RC 3715M TECHNICAL SPECIFICATION DESCRIPTION CMA 0204 HF CECC size RC 3715M 50 Ω; 47 Ω to 300 Ω Resistance range Resistance tolerance ±2% Temperature coefficient Approx. - 250 ppm/K Operation mode Standard Power Climatic category (LCT/UCT/days) 55/125/56 55/155/56 0.25 W 0.4 W Rated dissipation P70 (1) Limited by P70 Operating voltage, Umax.

However, resistance value drift increasing over operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a functional lifetime. (1) The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heatflow support of the printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature is not exceeded. Furthermore, a high level of ambient temperature or of power dissipation may raise the temperature of the solder joint, hence special solder alloys or board materials may be required to maintain the reliability of the assembly.
