What are the key features of PM127SH-100M-RC?
- 10 µH ferrite-core inductance with ±20% tolerance for power-stage filtering in DC-DC converters
- Ultra-low DCR of 19.5 mΩ minimizes conduction losses for high-efficiency power supply designs
- Large 4949 (12.7 mm × 12.7 mm) rectangular SMD footprint supports high saturation current handling
- Rectangular ferrite construction provides stable inductance across a wide temperature range for industrial power applications
What is PM127SH-100M-RC used for?
The PM127SH-100M-RC is used as an output filter inductor in synchronous buck and boost DC-DC converters in industrial power supplies, server power delivery networks, and motor-drive pre-regulators where low DCR and stable 10 µH inductance reduce output ripple current. Its high saturation current capability makes it suitable for point-of-load converters supplying FPGAs, DSPs, and high-current microprocessors. The 4949 SMD package supports standard reflow assembly in high-volume power electronics manufacturing.

Frequently Asked Questions
What is the inductance value and DCR of the PM127SH-100M-RC, and why do these parameters matter for power supply efficiency?
The PM127SH-100M-RC has a nominal inductance of 10 µH and a DC resistance of only 19.5 mΩ. In a synchronous buck converter, low DCR directly reduces I²R conduction losses; at 10 A output current this inductor dissipates approximately 1.95 W, making it efficient for high-current point-of-load supplies in server and industrial hardware.
What package size does the PM127SH-100M-RC use, and how does that affect PCB layout for power converters?
The PM127SH-100M-RC uses a 4949 case code corresponding to a 12.7 mm × 12.7 mm rectangular SMD footprint. This large body accommodates a high-volume ferrite core for elevated saturation current, and the flat SMD profile simplifies reflow soldering on double-sided PCBs in industrial and telecom power supply modules.
Which DC-DC converter topologies benefit most from the 10 µH, 19.5 mΩ PM127SH-100M-RC inductor?
Synchronous buck converters operating at 200 kHz to 500 kHz benefit most, as the 10 µH inductance limits peak-to-peak ripple current to manageable levels at these switching frequencies while the 19.5 mΩ DCR keeps conduction losses low. It is also suitable as the input choke for boost pre-converters in 48 V to 12 V power architectures used in data center rack power supplies.
Is the PM127SH-100M-RC RoHS-compliant, and what is the typical procurement lead time?
Yes, the PM127SH-100M-RC carries a RoHS-compliant (Pb-free) designation from Bourns. The factory lead time is listed at 16 weeks, so design teams targeting volume production should place orders well in advance of production milestones, or source from distributor buffer stock to meet shorter delivery windows.
