ESJ Microwave Technology RoHS compliant parts contain no more than 0.1% lead (Pb) by weight per homogeneous material, or else the devices may contain lead (Pb) for uses allowed by the RoHS Directive, as amended. ESJ Microwave Technology might use any of the following RoHS exemptions for RoHS compliant parts:
| RoHS Exemption | RoHS Exemption Description |
| 6(c) | Copper alloy containing up to 4 % lead by weight |
| 7(c)-I | Electrical and electronic components containing lead in a glass or ceramic other than dielectric ceramic in capacitors, e.g. piezoelectronic devices, or in a glass or ceramic matrix compound |
In determining the RoHS status of our products, ESJ Microwave Technology Co.,Ltd relies upon its suppliers’ material content data certification for each homogenous material in the product(s) that they or their subcontractors provide. The above statements above are valid and accurate to the best of our knowledge for ESJ Microwave Technology products in original packaging condition.
