A 5WR1J cement resistor is a 5-watt wirewound power resistor with a resistance value of 0.1 ohms and a tolerance of plus or minus 5% (indicated by the letter "J"). It features a ceramic case filled with cement for high heat resistance and flame-proofing.

Specifications

• Resistance Value: 0.1 ohms (1R variant can vary, always check datasheet for exact model)
• Power Rating: 5 watts, capable of dissipating higher energy loads compared to standard resistors 
• Tolerance: ±5% (denoted by "J" in the part number)
• Type: Cement or wirewound resistor, offering high heat resistance, mechanical stability, and low temperature coefficient 
• Dimensions: Typically around 21 x 9 x 9 mm, depending on manufacturer packaging 
• Material & Construction: Ceramic cement body or wirewound construction, providing durability in high-temperature environments 
• Applications: Commonly used in power supplies, amplifiers, TV sets, meters, sound equipment, and other circuits requiring stable power dissipation and high load capacity
