Frequently Asked Questions
What inductance value and DCR does the Bourns SDR0302-5R6ML offer for power converter designs?
The SDR0302-5R6ML provides 5.6 µH nominal inductance with a 0.16 Ω DC resistance in a 1211 SMD case, making it suitable for buck and boost DC-DC converters operating in the 200 kHz to 1 MHz switching frequency range in portable electronics and point-of-load power supply designs.
How does the shielded construction of the SDR0302-5R6ML reduce EMI in sensitive analog circuits?
The SDR0302-5R6ML uses a fully shielded ferrite core that contains magnetic flux within the core structure, reducing radiated EMI by more than 20 dB compared to unshielded drum-core inductors. This makes it compatible with FCC Part 15 and CISPR 22 Class B emission limits in consumer electronics switching power supplies operating at 300 kHz or higher.
Is the SDR0302-5R6ML an appropriate substitute for the SDR0302-6R8ML in a 5 V to 3.3 V buck converter?
The SDR0302-5R6ML at 5.6 µH is a lower inductance alternative to the 6.8 µH SDR0302-6R8ML in the same 1211 package. In a 5 V to 3.3 V buck converter, using 5.6 µH instead of 6.8 µH will increase ripple current by approximately 20%, which may require a slightly larger output capacitor to maintain the same output voltage ripple specification below 30 mV peak-to-peak.
