Optional component terminations

Coilcraft can add special termination finishes to meet specific requirements for all surface mount or leaded component. These special finishes will improve the solder fillet and ensure an exceptionally reliable solder joint.

RoHS gold terminations can be replaced with tin-lead finishes for exempt applications; special high temperature terminations are available for automotive or other demanding environments.

The following finishes can be applied to any component:
  • 63/37 tin-lead
  • 95.5/4/0.5 tin-silver-copper
  • Other alloys upon request
Once the new termination finish has been applied, the components are 100% tested for inductance and any other required electrical parameters.

Unlike third-party “tinning services” that use generic packaging materials, Coilcraft will tape, reel and package the components to original factory specifications. This protects the parts during shipping and assures trouble-free handling during manufacturing.

Ordering special terminations

Refer to the data sheet for the product you wish to order. The “L”, "E" or "R" near the end of the part number represents the standard RoHS termination code.

Substitute one of the following code letters for the “L” or "E":
  • S Tin-lead (63/37) – non-RoHS compliant
  • T Tin-silver-copper (95.5/4/0.5) – RoHS compliant
Substitute one of the following code letters for the “R”:
  • P Tin-lead (63/37) – non-RoHS compliant
  • Q Tin-silver-copper (95.5/4/0.5) – RoHS compliant
