High Precision 1M Ohm 3W E24 Resistor Carbon Film , High Power Resistors

Quick Detail:

• Temperature Range -55°C ~ +155°C

• ±5% tolerance

• High quality performance at economical prices

• Compatible with automatic insertion equipment

• Flame retardant type available

• Tin coated annealed copper wire

• Values below 1Ω or above 10MΩ are available by special request, please ask for details

Description:

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

Applications:

Can be installed into the power circuits of:

• Power supplies and inverters

• Uninterruptible Power Supplies

• Energy saving lamps

• Electronic Ballasts

• Filament Protection of various types of lamps

• Some types of heaters

• For higher power circuits ask about the MF73

and MF74 series surge suppressors.

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.

CF 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.

Table-1

Figure 1 Power derating curve

1.4 Rated voltage

The rated voltage shall be the D.C. or A.C.(R.M.S. at power frequency) voltage which corresponds

the rated power and the value of which is calculated from the formula below.

E=√(P×R) Where E: Rated voltage(V)

P: Rated power(W)

R: Nominal resistance(Ω)

Operating Temperature Range:-55℃～+155℃

2. Construction
