NOTE:
If required the resistors can also be supplied with straight leads and cropped leads. Please inform at the time of placing order.
* MP is the measurement point at which the resistance values must be checked using 4½ digit micro ohm meter with four wire system and insulated clips.
 
TYPICAL APPLICATIONS:
These low inductance and flame retardant resistors have evolved to become cost effective solutions for applications like the protection of the output transistor in audio visual equipment and current sensing in switching and linear power supplies. By providing low resistance value coupled with low inductance, the switching distortion with high frequency which affects the sound quality of audio equipment is minimised.The very nature of it's size and construction makes the BR series thin and light weight which translates into the saving of PCB space.
NOTE:
Due to recent technological advances, the ceramic cases used may be steatite ceramic / corderite ceramic / high alumina ceramic depending on the nature of the application. Hence the ceramic cases may be off-white / variations of brown and variations of gray; colours which are inherent to these ceramic materials.
