What are the key features of SRP1265A-6R8M?
- 6.8 µH nominal inductance in a 5349 case with carbonyl powder core provides stable permeability under DC bias for power conversion circuits
- 11.5 Ω DC resistance value balances core loss and conduction loss for efficient filtering in DC-DC buck and boost converters
- Precision moulded package construction ensures consistent inductance tolerance and mechanical robustness in automated SMT assembly
What is SRP1265A-6R8M used for?
SRP1265A-6R8M is suited for output filtering in DC-DC buck converters, boost regulators, and SEPIC topologies operating at switching frequencies between 100 kHz and 2 MHz where a stable 6.8 µH inductance is required. Its carbonyl powder core maintains permeability under load current, reducing output voltage ripple in point-of-load converters for embedded processors, FPGAs, and communication modules. Engineers also use it in EMI filter stages and choke applications within power supplies for industrial and consumer electronics.

Frequently Asked Questions
What is the inductance value and DC resistance of SRP1265A-6R8M?
SRP1265A-6R8M has a nominal inductance of 6.8 µH and a DC resistance of 11.5 Ω. The 6.8 µH value is well matched to switching frequencies from 100 kHz to 1 MHz in buck and boost converter designs, and the 11.5 Ω DCR contributes predictable conduction losses that engineers can account for in efficiency and thermal calculations for the power stage.
What core material does SRP1265A-6R8M use, and how does it affect performance under DC bias?
SRP1265A-6R8M uses a carbonyl powder core, which provides moderate permeability with a soft saturation characteristic. Unlike ferrite cores that saturate abruptly, carbonyl powder cores lose inductance gradually as DC bias current increases — typically maintaining 70% to 80% of the nominal 6.8 µH at rated current. This gradual rolloff prevents sudden converter instability and is advantageous in variable-load power supply designs.
In which DC-DC converter topologies is SRP1265A-6R8M most commonly deployed?
SRP1265A-6R8M is most commonly used in synchronous buck converters for point-of-load regulation at output voltages of 1 V to 5 V and load currents up to several hundred milliamps, as well as in boost converters for 5 V to 12 V step-up rails. The 6.8 µH inductance supports typical switching frequencies of 300 kHz to 600 kHz, achieving output ripple below 50 mV in well-designed PCB layouts. It also fits SEPIC and flyback auxiliary winding configurations.
What lead time and availability considerations apply when sourcing SRP1265A-6R8M?
SRP1265A-6R8M carries a factory lead time of 16 weeks from Bourns, making it important to plan inventory 4 months ahead for production builds. Design engineers should verify distributor stock levels early in the qualification phase, as the 5349 case size is a less common footprint than 4040 or 5040 standard inductors. Identifying a second-source inductor with equivalent 6.8 µH inductance and compatible DCR of 10 Ω to 13 Ω is recommended as a supply-chain risk mitigation strategy.
