3. INCREMENTAL CURRENT (INCR I) is the approximate current at which the inductance will be decreased by 5% from its initial (zero-DC) value because of saturation. If the current is increased beyond INCR I, the inductance will continue to decrease as shown by the saturation curve below. | ||||

| 2. CURRENT RATING (Rated IDC) is based on 0.75 watt power dissipation (I²R) for an approximate 20°C temperature rise. Depending on the application, these units may be operated at higher currents.
The core material for the 7230 series has been chosen for optimum current handling capability. Because this material has a relatively low volume resistivity, the core will appear as a shunt resistance on the order of 1 Kilohm, which may have to be taken into account when determining total power dissipation; e.g., if the induced voltage across the coil is 10 volts, there will be a V²/R loss on the order of 0.10 watt, in addition to the I²R losses associated with the winding. |
