What are the key features of SRP1206-2R0Y?
- 2µH inductance with ultra-low 6mΩ DC resistance minimizing conduction losses in power conversion circuits
- SMD 1206 (4949 case) ferrite-core rectangular construction for surface-mount power inductor applications
- 30% inductance tolerance suitable for non-critical filtering and energy storage in switching regulators
- General-purpose power inductor rated for high-current DC/DC converter output filter stages
- RoHS compliant (Pb-free, JESD-609 e2) for global regulatory compliance
What is SRP1206-2R0Y used for?
The SRP1206-2R0Y is designed for output filter inductors in DC/DC buck and boost converter circuits where a 2µH ferrite-core inductor with low 6mΩ DCR enables high efficiency at switching frequencies typically between 500kHz and 2MHz. Its SMD 1206 footprint suits compact power supply designs in portable electronics, wearables, and IoT devices where board space is limited but current capacity must support loads up to several amperes. It is also used in EMI filter networks and energy storage stages of point-of-load converters on multi-rail power supply boards.

Frequently Asked Questions
How does the 6mΩ DCR of SRP1206-2R0Y affect power efficiency in a DC/DC converter output filter?
The SRP1206-2R0Y has an exceptionally low DC resistance of 6mΩ, which means at a continuous output current of 5A, the conduction power loss is only 5² × 0.006 = 0.15W. This minimal loss makes it highly efficient for DC/DC buck converter output filters switching at 500kHz to 2MHz, compared to inductors with DCR above 50mΩ that would waste ten times more power at the same current.
What switching frequency range is the 2µH SRP1206-2R0Y inductance optimized for in a buck converter design?
A 2µH power inductor like the SRP1206-2R0Y is typically optimized for switching frequencies between 500kHz and 2MHz in buck converter designs, where the inductance provides adequate ripple current attenuation at the selected frequency. At 1MHz with a 5V input and 3.3V output, the inductor ripple current is approximately (5-3.3)/5 × 3.3/(2µH × 1MHz) ≈ 0.56A peak-to-peak, which is typical for low-ripple designs.
How does the ±30% inductance tolerance of SRP1206-2R0Y affect converter performance and is it acceptable for most applications?
The SRP1206-2R0Y carries a ±30% inductance tolerance, meaning the actual value can range from 1.4µH to 2.6µH. In DC/DC converter output filters, inductance variation shifts the ripple current by the same percentage, but because the control loop compensates for output voltage, this tolerance is acceptable for most non-precision applications. For designs requiring tighter inductor control, a ±20% or ±10% tolerance variant may be more appropriate, but 30% is standard for power converter output stages.
What current rating does the SRP1206-2R0Y support and how should designers calculate thermal derating at elevated temperatures?
The SRP1206-2R0Y ferrite power inductor is designed for high-current applications where the DCR of 6mΩ keeps self-heating low, with typical saturation current ratings in the SRP1206 series ranging from several amperes to over 10A depending on the specific variant. Designers should derate rated current by approximately 20% to 30% at ambient temperatures above 85°C to account for reduced core saturation margin and increased DCR at higher temperatures per the manufacturer's thermal derating curves.
