Walter Ultra Thin Long Electrode Alloy Resistor MHTC Series Selection Manual and Purchase Address: Click on the image to enter

 

The  Walter electronic ultra-thin long electrode alloy resistance MHTC series adopts the FR4 process. The Walter electronic chip long electrode alloy resistance MHTC series mainly includes 0805 and 1206 volumes, ultra-low resistance alloy resistance, and ultra-thin materials suitable for mobile phones, tablets, Bluetooth and other products. Below is an explanation of the parameters of the Walter small volume alloy resistance MHTC series.

 

The Suzhou Walter Electronic Walter alloy current detection resistor MHTC series has the following advantages:

 

1. Wide range of volume options: 0805,1206

 

2. Wide range of resistance options: 0.001R~0.005R

 

3. Wide range of power options: 1W

 

4. High accuracy: △ ≤ 1%

 

5. Low temperature coefficient: TCR < 50ppm/℃

 

6. High frequency response: H < 5.0nH

 

7. Excellent low galvanic effect (EMF<0.5uV/℃)

 

8. How to use RoHS and REACH halogen-free standards

 

9. The anti welding layer complies with UL94-V0 level

 

10. Low inductance (<0.05uH 10MHz)

11. Process: FR4
