TIDA-01513: Use of MELF Resistors

Sibi Selvaraj
Prodigy 60 points
Part Number: TIDA-01513


Tool/software:

Is it necessary to only use MELF resistor for the resistors ladders or can we use any SMD resistor of the same resistance value and tolerance level? Kindly elaborate on the technial aspect of this.

    Hi Sibi,

    In general you can use any resistor with sufficient voltage and power rating that fit your design. MELF resistors are beneficial in this application because their overload withstand capability - they can absorb transients.

    In any case you need to check for static load (power, voltage temperature & derating) as well as transients that can appear on the HV bus.

    Kind regards,

    Tomas
