## Performance indicators 

## Approvals & Compliances 

RB common-mode chokes are mainly used to filter EMI noise on AC power lines up to 600 VAC but they are as well applicable in DC power lines of photovoltaic installations or similar applications up to 1000 VDC. EMI noise of electronic equipment can go to the power lines and disturb the proper function of other devices like TV sets or radios. Thus noise generated by the equipment from switched power electronics or by high slew rates of controllers needs to be filtered. RB common-mode chokes are used to suppress EMI noise in PCB integrated filter designs with line bypass capacitors or in combination with single phase filters for extra low leakage filter designs.

## **Available Supporting Material** 

## **Accessories** 

For all RB choke types an evaluationboard is available (not including capacitors and RB chokes) 

All boards feature voltage ratings according to the chokes usable on the board - up to 600VAC/ 1000VDC. 

The capacitors used need to be selected according to application and safety level. 

Recommended are Y1 and X1 capacitors with a voltage rating of at least 600VAC and 1000VDC. 

The pitch for Y-capacitors (between phase and PE) is 15 or 22.5 mm. With a max outer dimnesion of 12 x 26 mm (w x l). 

The pitch for X-capacitors (between phases) is 22.5, 27.5 or 37.5 mm. With a max outer dimnesion of 28 x 40 mm (w x l). 

For discharge reason a resistor can be fitted in parallel to the X-capacitors. 

All connections to the boards are done with M6 screw terminals (recommended torque is 2.5 Nm.
