RMCF / RMCP Series

General Purpose Thick Film Standard Power

and High-Power Chip Resistor

Stackpole Electronics, Inc.

Resistive Product Solutions

Part Marking Specifications

The thermal resistance of the RMCP will be similar to the RMCF. For example, the RMCF2512 and the RMCP2512 will have similar

surface temperatures at 1W; the RMCP is designed to withstand higher temperatures associated with high power levels.

For shared E24/E96 values, 1% tolerance product may be marked wit three digit marking instead of the standard four-digit marking

for all other E96 values. All E24 values available in 1% tolerance are also marked with three-digit marking.

A two-digit number is assigned to each standard R-Value (E96) as shown in the chart below. This is followed by one alpha character

which is used as a multiplier. Each letter represents a specific multiplier as follows:

Explanation

Value

01B

01 means 10.0 and B = 100

10.0 x 100 = 1K ohm

E96

25C

25 means 17.8 and C = 1,000

17.8 x 1,000 = 17.8K ohm

93D

93 means 90.9 and D = 10,000

90.9 x 10,000 = 909K ohm

5% Marking

The nominal resistance is marked on

the surface of the overcoating with the

use of 3 digit markings.

0201 and 0402 are not marked.

1% Marking

The nominal resistance is marked on

the surface of the overcoating with the

use of 4 digit markings.

0201 and 0402 are not marked.
