JR Series High Power Jumper Chip The Ohmite JR series high current jumpers are rated up to 100 amps and provides a max resis- tance range of 0.5m to 0.2m ohms. This minimizes effects on the designed circuit. Five industr y sizes are available. The JR series also provides great insulation resistance over 100M ohms. SeRieS SPecificationS Max. Max. Series Res.
