7. Marking

7.1 ±2% & ±5%(E24) : RMF06 / RMF10 / RMF12 / RMF13 / RMF20 / RMF25

Resistance value is expressed by 3 digits, the first two digits represent the significant figures of

nominal resistance value inΩ, and the third digit represents exponent for base of 10.

E.G. :, 102 = 10×10

7.2 ±0.5% , ±1% (E96 ) : RMF10 / RMF12 / RMF13 / RMF20 / RMF25

Resistance value is expressed by 4 digits , the first three digits represent the significant

figures of nominal resistance value inΩ, and the fourth digit represents exponent for base of 10.

E.G. : 1000 = 100×10

0.5% , ±1% ( E96): RMF06

When the marking space is too small in such small-sized resistors as RMF06, the marking can not

made by 4 digits and may be made by two digits combined with one English capital.
