Cal-Chip Electronics, Incorporated

Thick Film Chip Resistors - RM Series

“Fixed Chip Resistors” manufactured for more compact electronic com-

ponents 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.

MARKING

Resistance value in three digit designation system is marked on the

glasscoat. Illustrated is a resistor of 15KΩ. Four digit resistance desig-

nation 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 and ±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

2. For E-96 Series (±1%-F Tolerance)

In 0805, 1206, and 1210sizes:

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

3. For E-96 Series (±1%-F Tolerance) in 0603 size
