High Alumina 100MR Cement Resistor 5 Watt For Printed Circuit Boards

 

Quick Detail:

 

1.Small size,resistant to vibration,humidity and heat,good dissipation,low noise and no annual shift in resistance value,low price
2.UCHI is equipped to design and produce custom components to meet many design and reliability demands. Contact us with your specific needs.
3.Delivery:5-7days
4.Conforms to the ROHS standard and the LEAD-FREE non-lead standard.

 

 

Description:

 

1.cement resistors are made by winding resistance wires around non-alkaline ceramic core,which is added with a layer of heat and humidity resistant and non-corrosive protective material.
2.The wire wound resistor is then placed in a square ceramic package sealed with special nonflammable heat-resistant cement.
3.For high resistance value,wires are replaced by metal oxide films.

 

 

Applications:

 

Complete insulation suitable for printed circuit boards,Power supplies ,Voltage dividers ,Motor controllers ,Automotive applications ,Power electronics circuits.

 

 

Specifications:

 

  1. General

 

1.1 Scope

This specification is available for Cement 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.

 

   

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.
