    Product Description


    HTB1YzdRMXXXXXb1XpXXq6xXFXXXN.jpg

    Metal film resistor

    The metal film resistance is the resistance so far is widely used, its high precision, stable performance, simple structure and lightweight. Play an important role in electronic industry and high precision military aerospace etc..









    Multi-layer ceramic capacitorTU3.jpg

    Carbon film resistor with low cost, electrical 

    performance and poor stability, generally not 

    suitable for general  resistor. But because 

    it is easily made of high resistance film, 

    so is mainly used for high resistance

     high voltage resistor. The use of high 

    voltage resistors.







    HTB1Ef8SMXXXXXaaXFXXq6xXFXXXX (3).jpgSMD series

    Wire wound resistor is mainly used to play a buck, shunt, load, feedback, transfer, matching the low frequency AC circuit, or in a power supply circuit to the absorber and the divider, can also be used as shock attenuation in the transformer circuit and adjustment circuit of the pulse formation and shunt. In addition, can also be used to filter capacitor discharge rectifier and spark. At the same time can be widely used in the field of home appliances, medical equipment, automotive, railway, aviation, military equipment etc..



    Thick film resistorHTB1AGJTMXXXXXXVXFXXq6xXFXXXQ.jpg

    The metal oxide made of precious metals silver palladium, ruthenium and rhodium (such as palladium oxide and ruthenium oxide etc.) and glass glaze binder mixed into slurry, coated on the insulating framework, with high sintering temperature.

    This resistance range, low price, small temperature coefficient, good moisture resistance, the resistor and thick film resistors.










    HTB1qXBBMXXXXXawapXXq6xXFXXXD.jpgcement resistor

    Cement resistance is the resistance wire wound in alkaline resistant ceramics on the outside with heat resistance, wet resistance and corrosion protection materials and the fixed winding resistance in the square porcelain box, with special non flame cement filling and sealing. The lateral cement resistance is mainly made of ceramic material (generally can be divided into high aluminum porcelain and feldspar porcelain).

    Q2. How can I get a sample to check your quality?

    A:After price confirmation, you can require for samples to check our quality counter display. 


    If you need the samples, we will charge for the sample cost .But the sample cost can be refundable after order confirmation when your quantity of the order is more about the MOQ. 

    Q3. You can provide some samples for me?

    A: Yes, we can provide free samples to you, but the freight need you to bear. 

    Q4.I am a small wholesaler, do you accept small order? 

    A: It's no problem if you are a small wholesaler, we would like to grow up with you together.

    Q5. How long can I expect to get the sample? 

    A: After you pay the sample charge and send us confirmed files, the samples will be ready for delivery in 3-7 days. The samples will be sent to you via express and arrive in 3-5 days. You can use your own express account or prepay us if you do not have an account.


    Q6. What about the lead time for mass production?
