# ~5 h2 Z( r+ A, B Z7 I& N: w% YFor common-mode termination, a split termination consisting of two 1 kΩ resistorsand a 4.7 nF capacitor, with a 100 kΩ resistor to GND, can be connected to the signallines between the coupling capacitors and the connector. For reasons of symmetry,the tolerance of the two 1 kΩ resistors should be within ±1 %. The power rating shouldbe higher than 0.4 W (anti-surge) in order to survive EMI disturbances. Please checkimplementation details and other requirements with the customer (OEM). No specificpower rating is specified for the 100 kΩ resistor and 4.7 nF capacitor, but componentsshould be rated max ≥50 V.3 D' _: b% {/ D. @
