CAPACITORS
For the Johanson Technology surface mount High-Q capacitor line, there are RoHS compliant families available. C-SERIES ARE NOT COMPLIANT WITH RoHS
The C-Series family will be made obsolete late this year (2005) as it cannot meet the RoHS directive because of a Cadmium compound ingredient in the ceramic body.
S-SERIES ARE COMPLIANT WITH RoHS
The S-Series family, which replaces the older C-Series family, has lead free, 100% tin plated terminations, and it can meet the RoHS directive. This does not include the optional termination code "T" which signifies tin-lead terminations. All S-Series size families (R07, R14 & R15) have lead content in the ceramic body that is way under the RoHS 1000 ppm maximum. Therefore, the entire S-Series family is RoHS compliant.
L-SERIES ARE COMPLIANT WITH RoHS
The L-Series family also has lead free, 100% tin plated terminations, and can meet the RoHS directive. This does not include the optional termination code "T" which signifies tin-lead terminations. The lead content in the part is way below the 1000ppm threshold for all parts less than 4.7 pF. For parts greater than or equal to 4.7 pF, the lead content is greater than 1000 ppm in the ceramic body (but NOT in the termination), the RoHS directive exemptions given in the RoHS Directive Annex items 5 & 7d apply. All other RoHS prohibited materials are non-existent in this family. Therefore, the entire L-Series family is RoHS compliant.
E-SERIES ARE COMPLIANT WITH RoHS
The E-Series family which was designed for low loss, high current and high voltage applications has lead free, 100% tin plated terminations, and it can meet the RoHS directive. This does not include the optional termination code "T" which signifies tin-lead terminations. All E-Series size families (S42, S48 & S58) have lead content in the ceramic body that is way under the RoHS 1000 ppm maximum. Therefore, the entire E-Series family is RoHS compliant.
LASERTRIM
The laser trim capacitor series meets the RoHS directive as long as a dielectric of "N", "S", or "M" is shown in the part number.
SINGLE LAYER
The single layer capacitor series mostly meet the RoHS directive. However, some dielectrics do not. Please consult the factory for further clarification. In all instances, the terminations are lead free.
INDUCTORS
RF CERAMIC INDUCTORS ARE COMPLIANT WITH RoHS
For our monolithic inductor family, the entire product family is RoHS compliant, and has lead free terminations when manufactured after June 1, 2002. The ceramic body has a lead compound in it that is greater than 1000 ppm (there is no lead in the termination), whereby the RoHS directive exemptions given in the RoHS Directive Annex items 5 & 7d apply. All other RoHS prohibited materials are non-existent in this family. The part number will not change to signify compliance, but the date code (which is part of the lot code) needs to be greater than 226-XXXX (which is the first week of June 2002).
WIREWOUND INDUCTORS ARE COMPLIANT WITH RoHS
For our wirewound inductor family, the entire product family is (and always was) RoHS compliant (all prohibited materials are absent), and has lead free terminations, regardless of date of manufacture.
RF COMPONENTS
RF Components
For our RF component line, including filters ( LPF, HPF, BPF, and Filter-Baluns ), antennas, couplers, baluns, and diplexers, the entire family has lead free terminations if manufactured after August 1, 2004. The ceramic body has a lead compound in it that is greater than 1000 ppm (there is no lead in the termination), whereby the RoHS directive exemptions given in the RoHS Directive Annex items 5 & 7d apply. All other RoHS prohibited materials are non-existent in this family. The part number will not change, but the date code (which is part of the lot code) needs to be greater than 433-XXXX (which is the first week of August 2004).
Upcoming New Product Roadmap
There are upcoming new products at Johanson Technology, which will have zero lead in the part (including the ceramic body). Check our web site periodically for future updates.
