MLRF0603 & MLRF0805 Sn/Pb Terminated Series Address Market Need for Solder-Friendly Components

Gowanda, NY (USA) – Gowanda Electronics recently achieved qualification to the military’s MIL-PRF-83446 specification for its MLRF0603 and MLRF0805 series of RF surface mount wirewound coil, ceramic core chip inductors with tin/lead terminations.  These are the first series in the industry to attain Qualified Product List (QPL) status for this particular Department of Defense specification.  Gowanda was the first to introduce gold-terminated 0603 and 0805 chip inductors several years ago.

Tin/lead solder terminations are necessary for processes where reflow soldering is the component assembly method.  In such situations, gold terminations require additional processing to pre-tin the terminations prior to assembly in order to prevent gold embrittlement.  The tin/lead terminated QPL inductors now available from Gowanda provide an effective time-saving, solder-friendly solution.

The MLRF0603 and MLRF0805 series are designed for RF applications in military, aerospace and defense communities.  This includes use in communication, guidance and security applications, as well as radar, test & evaluation and special mission applications.  These series can also be used in other high frequency applications around the world where the rigorous testing associated with these QPL-approved inductors makes them desirable for high reliability (hi rel) designs, or wherever QPL-approval provides additional assurance of performance and reliability.

Gowanda Now Offers 0603 and 0805 Chip Inductors with Au or Sn/Pb Terminations for MIL-PRF-83446 Applications

Gold terminations are available as well as tin/lead solder terminations.  The Sn/Pb solder-coated termination meets Termination Finish Code B and Code F of the MIL-PRF-83446 mil spec.  The Au termination meets Code A.  Operating temperature for each series is -55ºC to +125ºC.

Gowanda Electronics’ proprietary epoxy capping technique provides uniform dimensional stability for pick-and-place assembly and assures environmental and mechanical protection of the coil.
