**Bourns is using the definition that appears to be the prevalent definition used as the industry standard at this time. The Bourns definition of “halogen-free” is:
Bromine (Br) content:
≤ 900 ppm; Chlorine (Cl) content: ≤ 900 ppm; Total Br + Cl content: ≤1500 ppm.
Specifications are subject to change without notice.
The device characteristics and parameters in this data sheet can and do vary in different applications and actual device performance may vary over time.
Users should verify actual device performance in their specific applications.
