Marking
3-digits marking for E24 series 1% ,5% products. For values up to 9.1 the R is used as a decimal point. For values of 10.0 or greater, the first 2 digits apply to the resistance value and the third indicates the number of zeros to follow. Example: 4.7 = 4R7, 10 = 100, 100 = 101, 6800 = 682, 47000 = 473. No marking for WA04Y chip resistors array and E96 series resistance.
Functional Description
Standard nominal resistance values are from the E24 series for 5% tolerance and E24/E96 series for 1% tolerance, in accordance with IEC publication 60063. Power dissipation is dependent on ambient temperature; refer to derating curves.
Mounting and Soldering
Suitable for automatic placement systems on ceramic substrates and PCBs. End terminations ensure reliable soldering. Can withstand immersion in a solder bath of 260C for 10 seconds. Tested for solderability at 235C for 2 seconds. No leaching at 260C for 30 seconds.
Test and Requirements (JIS C 5201-1 : 1998)
Tests are carried out according to IEC publication 115-8, category LCT/UCT/56, and meet EIA, EIAJ, and JIS requirements. Standard atmospheric conditions apply unless otherwise specified.
