Surface Mount Resistors/Flat Chip Jumper Resistors RK73Z
Coating color : Green (1H, 1E)
Black (1F, 1J, 2A, 2B, 2E, W2H, W3A)
  Construction
   
Surface Mount Resistors/Flat Chip Jumper Resistors RK73Z Construction
1. Protective coating
2. Resistive film
3. Inner electrode
4. Ni plating
5. Solder plating
6. Ceramic substrate
 
Features
 
• Small and light weight.
• Excellent heat resistance and weather resistance, because of the use of glaze thick film as resistive film.
• High stability and high reliability because of the triple-layer structure of electrode.
• Applicable to various kinds of automatic mounters for taping, etc.
• Suitable for both flow and reflow solderings.
• Products with lead free termination meet EU-RoHS requirements.
EU-RoHS regulation is not intended for Pb-glass contained in electrode, resistor element and glass.
