High Pulse Load MELF Resistor
REG.-Nr. B583
CMB 0207 speciality MELF resistors with advanced pulse
load capability are the perfect choice for the protection of
circuitry with signal and mains input lines from surge pulses.
The resistors are also suitable for circuits exposed to high
levels of electromagnetic interference or electro-static
discharge. The applications are in all fields of automotive,
telecommunication, industrial and medical equipment.

Notes
• These resistors do not feature a limited lifetime when operated within the permissible limits. 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.
2. Specified power rating requires dedicated heat-sink pads.
3. Film temperatures above the specified range may be permissible, e.g. 175 °C. Please contact the factory for details.
