Murata Shielded Inductors Provide Power Line Filtering For Applications With EMI Susceptibility

Murata Power Solutions announced the new 1200RS and 1200LRS series of inductors for providing power line filtering in low to medium current applications such as switching power supply circuits. An integral ferrite shield makes them especially useful in designs that are susceptible to electromagnetic interference (EMI).

The through hole, radial leaded devices have compact overall dimensions of 10.0 x 8.5mm that support their inclusion in designs where PCB space is limited. The 1200LRS series is available with inductance values ranging from 6.8µH to 22mH and dc current ratings up to 4.7A I_DC. The 1200RS series offers higher current versions with the same footprint. Inductance values extend from 10µH to 1mH and maximum current ratings to 4.6A IDC. All parts have a low dc resistance to help maximize efficiency.

Operating temperature range of the 1200RS and LRS series is -40 to +85°C. The new devices use UL 94V-0 approved materials, are fully RoHS compliant, and have backward compatibility with Sn/Pb soldering systems.

Dependent on series, prices range from US$0.41 to US$0.50 in high volume quantities.
