yes you are right! Farnell has E96 resistance values of Panasonic SMD pulse proof high power Resistor series ERJP on stock!
ERJP03 (0603; 0.2W; E96)
ERJP06 (0805; 0.25W; E96)
ERJP08 (1206; 0.33W; E96)
ERJP14 (1210; 0.5W; E96)
Reason for stocking this wide portfolio and variety of resistance values is, that there is a significant trend in the market towards downsizing!
Of course 1 reason is to safe space, but the other reason is increasing requirements especially from Automotive market towards more heat-shock cycles. Therefore smaller size, plus soft termination contribute towards significant increase of solder joint reliability!
By using ERJP series instead of Std. Thick Film Resistor customer can at least reduce 1 case size by haveing same Power Rating!
Farnell understand this trend and therefore offer a wide choice of products and E96 resistace values to the market and its engineers!
In case of further questions please ask me any time!
I am currently using Melf resistor for Surge Characteristics, reading the above my understanding is that Panasonic Anti Surge would be an excellent alternative?
What are the advantages of using Anti surge? Are there any Advantages of Cost Reduction? Improvement of Mounting Speed VS Melf?
Is this series suitable for both reflow soldering & Flow Soldering?
Sorry for so many questions, are the above series mentioned by MS Kubo AECQ-200 Approved?
Currently we can see significant trend in the market to replace cylindrical MELF resistor by SMD resistor!
Several reasons:
- improvement of mounting speed
- better solder joint reliability
- easy mounting
- cost reduction
Normally MELF is used for 1 of below 3 reasons. Depend on the reason we can provide s SMD solution which you can test as all these parts are stocked at Farnell.
Why doe engineer still use MELF?
1.) Surge withstanding
-> SMD surge prrof resistors available now ERJP, ERJT series
2.) Stability over lifetime, precision
-> SMD high reliability, stability over life time Thin Film Reistors available ERA-series
-> no drift of resistance value even under toughest environment conditions
3.) high power required
-> SMD Wide terminal series available ERJB
Of course all Panasonic SMD resistors correspond to AEC-Q200!
