K 33 E E-96 For the dimension type of 63, express the resistance value with three code, the first two digit code denote the resistance of E-96 series, and the third code of letter denote the multiplier (see the table three and four ). 2M R The decimal point should be expressed by R. 5.6 The jumper should be expressed by For the dimension type of there is no mark on the glass side. IEC IEC E24 For the resistance which don't belong to IEC serial, use the resistance of IEC serial which is most close to the required resistance of non-iec serial for replacement.

Marking TD3G47BT 47=4.7K R5=.5 To use four digits code represent resistance value, 47=4.7K R5=.5 E24 E96 E96. When resistance value belongs to E24 as well as E96 series, we suggest preferentially use E96 series. K=2, Marking for Size Resistor For size resistor, express the resistance value with four digits code; K 63 Marking for 63 Size Resistor 63-E96 For resistance value belongs to E96 series, express the resistance value with three digits code. 2M 63-E24 For resistance value belongs to E24 series, express the resistance value with three digits code. K The decimal point should be expressed by "R" For the dimension type of 2 42 there is no mark on the glass side. 89
