What are the key features of SRP1265A-R22M?
- 0.22 µH inductance with 0.6 Ω DC resistance (DCR) in a compact 5349 (12.5 × 12.5 mm) shielded package for high-current DC-DC converter stages
- Carbonyl powder core material provides magnetically shielded construction that reduces EMI emissions in switch-mode power supply designs
- General-purpose power inductor configuration supports buck, boost, and SEPIC converter topologies in industrial and consumer electronics
What is SRP1265A-R22M used for?
The SRP1265A-R22M is designed for high-current buck and boost converter output filter stages in portable electronics, server power supplies, and industrial motor drives where low DCR and compact 5349 package dimensions are required. Its shielded carbonyl powder construction minimizes magnetic interference with adjacent analog circuits on densely populated power management boards.

Frequently Asked Questions
What inductance value and DCR does the SRP1265A-R22M provide, and how do these affect converter efficiency?
The SRP1265A-R22M has a nominal inductance of 0.22 µH and a DC resistance of 0.6 Ω. At a 10 A output current, the 0.6 Ω DCR produces 0.6 W of conduction loss, so careful thermal management is required. The low 0.22 µH value suits high-frequency buck converters operating above 500 kHz, reducing inductor size while maintaining acceptable ripple current.
Which converter topologies are compatible with the SRP1265A-R22M power inductor?
The SRP1265A-R22M is a general-purpose shielded power inductor compatible with buck (step-down), boost (step-up), buck-boost, and SEPIC converter topologies. Its 0.22 µH inductance is particularly suited for high-frequency switching regulators above 500 kHz, where small inductance values keep the physical component size small while achieving less than 30% peak-to-peak ripple current in typical designs.
What does the 5349 case code indicate about the SRP1265A-R22M package size for PCB layout planning?
The 5349 case code corresponds to a 12.5 mm × 12.5 mm footprint with an approximate height of 9 mm, making it one of Bourns' larger power inductor packages capable of handling higher saturation currents. This footprint should be allocated at least 2 mm of clearance on each side in the PCB layout to allow adequate airflow and prevent mutual inductance coupling between adjacent magnetic components.
