Construction

Surface Mount Resistors/Flat Chip Resistors RK73B 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 are ensured by the use of metal glaze thick film.
•	High stability and high reliability with the triple layers 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.
