Open circuit inductance test parameters : - Inductance values up to 100uH: 100kHz - 0.10Vac with 0Adc bias - Inductance values higher than 100uH: 20kHz - 0.10Vac with 0Adc bias. 2. The heating current is the DC current required to raise the component temperature by 40°C at 25°C ambient temperature. The heating current is determined by mounting the component on a typical PCB and applying the current for 30 minutes. 3. The saturation current Isat is the current which causes the inductance to drop by 30% at an ambient temperature of 25°C. This current is determined by placing the component in the specified 4. 5. 6. 7. ambient environment and applying a short duration pulse current (to eliminate self-heating effects) to the component. Performances @ 25°C ambient temperature. Parallel connection mode (1,2 - 3,4); Serial connection mode (1-4) with (2-3) short circuited. Optional Tape and Reel packaging can be ordered by adding a "T" suffix to the part number (i.e. PF0553.102NL becomes PF0552.103NLT). Pulse complies to industry standard tape and reel specification EIA481. The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range.
