Surface Mount Resistors/Chip Networks (Concave Termination) CNB
Coating color : Black
  Construction
   
Surface Mount Resistors/Chip Networks (Concave Termination) CNB Construction
1. Protective coating
2. Resistive film
3. Inner electrode
4. Outer electrode
5. Ceramic substrate
 
Features
 
More advancement in the mounting density than individual chip resistors.
Mounting cost reduction by decreasing the number of parts mounting times.
Higher self-alignment effect in reflow-soldering process.
Suitable for an image recognition mounter due to square corner design.
Suitable for both reflow and flow solderings.
4 or 8 elements are integrated for Pull-up/ Pull-down.
Easy to make a PWB layout with a zigzag electrode.
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.
 
 
Applications
 
Resistors for Pull-up/Pull-down for digital circuits

Please note that network resistors generate higher heat rather than single flat chip resistor even under rated power output.
Rated voltage= √(Power Rating×Resistance value) or Max.working voltage, whichever is lower.
   
Derating Curve

Surface Mount Resistors/Chip Networks (Concave Termination) CNB Derating Curve
For resistors operated at an ambient temperature of 70 or above, a power rating shall be derated in accordance with the left derating curve.
