Thick Film Chip Resistors - RM Series
“Fixed Chip Resistors” manufactured for more compact electronic compo-
nents and automatic mounting system.
These Chip Resistors have electrical stability and mechanical stress due to
used reliable metal glazed paste printed on Alumina substrate. Resistors will
reduce your cost and save developmental time.
FEATURES
1. Very small, thin and light weight.
2. Both flow soldering and reflow soldering are applicable.
3. Owing to the reduced lead inductance, the high frequency
characteristic is excellent.
4. Suitable size and packaging for surface mount assembly.

Thick Film Chip Resistors
Resistance value in three digit designation system is marked
on the glasscoat. Illustrated is a resistor of 15KΩ. Four digit
resistance designation system is applied to RM12 and E-96
Series. For example, 1502 designated 15KΩ. (The last digit
specifies the number of zeros.)
1.
For E-24 Series (±5%-J, ±2%-G, ±10%-K Tolerances)
In 0603, 0805, 1206, 1210, 2010 and 2512 sizes:
3 DIGIT SYSTEM
- First two digits are significant and
third digit is multiplier, “R” indicates decimal on values
under 10 ohms.
Examples:
10R = 10 ohms
102 = 1k ohms
470 = 47 ohm
103 = 10k ohms
101 = 100 ohms
104 = 100k ohms
105 = 1 megohms
For E-96 Series (±1%-F Tolerance)
In 0805, 1206, and 1210 sizes:
4 DIGIT SYSTEM
- First three digits are significant and
fourth digit is multiplier “R” indicates decimal on values
under 10 ohms.
Examples:
10R0 = 10 ohms 1003 = 100k ohms
1000 = 100 ohms 1004 = 1 megohms
1001 = 1k ohms
1052 = 10.5k ohms
1002 = 10k ohms 2213 = 221k ohms
For E-96 Series (±1%-F Tolerance) in 0603 size
