Hello,
We have a 0R56 , 1206 resistor which suffers the attached inrush power pulse at switch-ON. (shown in 2 scope shots of the same thing, but one is a close up)
The initial high pulse, which is 120W high, has a base of just 40ns. Would there be any chance that over say 10 years this pulse could eventually lead to the destruction of this resistor? The product is switched on once per day.
(after the initial high pulse, there is a 140us period where the resistor power is just 0.6W, and this is obviously harmless)
Please answer with relation to the following resistor…..
ERJ-8BQJR56V

Also, please answer with this standard 0.25W 1206 resistor in mind…

We know we can buy resistors such as RCWE1206 series that can definitely handle this pulse, but they are significantly more expensive, and few in number, so may have supply issues.
