Description:

Metal film resistors are a fixed form type resistor. They are constructed out of a ceramic carrier with a thin pure metal film around it, that functions as resistive material.

Applications:

-Telecome

-Test and Measurement

-Pure tin plating provides compatibility with lead (Pb)-free and lead containing soldering processes

Specifications

1. General

1.1 Scope

This specification is available for Carbon Film Fixed Resistor manufactured by,it accords with RoHS test of Environment related substance requirement.

1.2 Type designation (example)

The type designation shall be in the following form and as specified.

MF 1/4 W 10K J T52

1.3 Rated power

Rated power is maximum power which can be continuously loaded at specified ambient temperature

70℃,as Table-1;however when the ambient temperature exceeds 70℃,rated power should be determined

from the derating curve of Fig.1.
