Product specifications
1. Open Circuit Inductance Test Parameters: 100kHz, 0.25 Vrms, 0.0 Adc
Parallel: (1,2 -4,3) Series: (1-4) tie (2-3)
2. RMS current for an approximate DT of 40°C without core loss.
It is recommended that the temperature of the part not exceed 125°C.
3. Peak current for approximately 30% roll-off at 20°C
4. DCR limits @ 20°C
5. Applied Volt-Time product (V-μS) across the inductor. This value represents
the applied V-μS at 100KHz necessary to generate a core loss equal to 10%
of the total losses for a 40°C temperature rise.
6. Turns Ratio (1:3):(2-4) 1:1
7. Part number definition: DRQxxx-yyy-R
- DRQxxx = product code and size,
- yyy = inductance value in μH,
- R = decimal point. If no R is present, third character = # of zeros
