SMT/Radial Lead Inductors reduce EMI in power applications.
October 1, 2008 -
Suited for low- to medium-current applications, 1500 and 1900R series RoHS-compliant radial leaded inductors respectively feature current ratings to 16.2 and 7.8 A IDC max and inductance values from 1.0 µH to 1.0 mH and 4.7 µH to 100 mH. Low-profile (0.39 in.) 4200 and 4300 series toroidal SMT inductors, suited for use in switching AC/DC power supplies and DC/DC converters, respectively offer max current ratings of 15.4 and 22.4 A IDC and inductance from 1.27-17.6 and 2.1-4.0 µH.

New Surface Mount & Radial Leaded Inductor Ranges Help Engineers Reduce EMI in Power Applications
o Thru-hole radial lead and low-profile surface-mount toroidal parts added
o Total of over 50 new part numbers
o Inductors for filtering noise in high current designs
Murata Power Solutions has enhanced its radial lead and toroidal surface-mount inductor portfolios with the addition of four new ranges of RoHS compliant components. The introductions comprise over 50 new part numbers that reinforce Murata Power Solutions' reputation as a provider of industry-leading magnetic products.
The 1500 and 1900R series are general purpose radial leaded inductors suitable for providing filtering in low to medium current applications such as those found in power supplies. The 4200 and 4300 series of toroidal surface-mount inductors meanwhile are designed for use in switching AC/DC power supplies and DC/DC converters. Their low-profile design makes them ideal for use in designs where component height is restricted.
Both the 1500 and 1900R series offer low DC resistance. The 1500 series is available with current ratings up to 16.2A IDC and inductance values that range from 1.0µH to 1.0mH. The 1900R series is rated to 7.8A IDC with inductance values of between 4.7µH and 100mH. Custom parts are available on request. Both ranges are supplied in cartons of 40, are fully compatible with RoHS soldering systems and have backward compatibility to Sn/Pb solder processes. Operating free air temperature range is -40ºC to +85ºC.
The 4200 and 4300 series toroidal surface-mount inductors have compact overall dimensions with a maximum overall height of less than 0.39". Both ranges utilize UL94 V-0 package materials, are pick & place compatible and meet J-STD-020C reflow requirements with backward compatibility to Sn/Pb soldering systems. The toroidal construction of the new inductors aids design engineers by helping minimize EMI issues. The 4200 series has a current rating of up to 15.4A IDC and a choice of inductance values between 1.27µH and 17.6µH. The 4300 series comprises parts with inductance values ranging from 2.1µH to 4.0µH and a maximum current rating of 22.4A IDC. Operating temperature for both ranges is -40ºC to +125ºC.
Pricing is between $0.87 and $1.69 for a quantity of 1k.
