TTE Filters offers RoHS Compliant and Lead Free Alternatives

In its ongoing commitment in supplying superior quality products to the RF & Filters industries and meeting world wide environmental regulations TTE now offers RoHS compliant components produced in accordance with the RoHS-2 2011/65/EU European Parliament Restriction of Hazardous Substances Directive banning the use of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE). Currently TTE uses only “lead solder alloys” in its products and does not plan to introduce any of the remaining 5 banned substances into the future release of any new products.

TTE's Definition of a "Lead Free Component"

TTE defines a lead free component as one that is produced with a true 100% lead free solder alloy on both the internal joint connections and external lead finishes of the component.

Note: TTE does not claim the exemption outlines in paragraph 7 of the Annex table allowing a solder alloy of 85% lead or greater to be used in its lead free products.  Please refer to the EU Directive for further information.

TTE's Definition of a RoHS Compliant Component

TTE defines an RoHS component the same as its Lead Free component. A lead free component can be considered as being RoHS compliant by meeting the .1% of the homogeneous material of the device requirement and in addition is also compatible with 260°C soldering processes; verified through internal product testing.

Part Number Derivation

  1. Series
  2. # of poles / The “T” option specifies a filter with low THD for ADC/DAC testing.  When selected the min THD is > -80dBc, -96dBc typically.
  3. “R” RoHS compliant.  Allow for longer lead-time
  4.  F-3dBc
  5. Terminations
  6. Case selection from the case selection guide.  Filter with “T” option are larger.

Lead Free Solder Type

TTE has selected 3 types of Lead Free solder alloys dependent on product style. Please consult factory for specific type when placing order.


When ordering RoHS/Lead Free products, the R must be assigned within the part number and identified on the purchase order as described in the marking example above.
