High Pulse Load MELF Resistor
CMA 0204
Vishay Beyschlag
CMA 0204 speciality MELF resistors with advanced pulse
load capability are the perfect choice for the protection of
circuitry with signal or mains input lines from surge pulses.
The resistors are also suitable for circuits exposed to high
levels of electromagnetic interference or electrostatic
discharge. The applications are in all fields of automotive,
telecommunication, industrial and medical equipment.
FEATURES
• Special carbon film technology
• Up to 4 kV single pulse capability
• Up to 70 W continuous pulse load
• Green product, supports lead-free soldering.
APPLICATIONS
• Automotive
• Telecommunication
• Industrial
• Medical equipment

Note
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.
