Ordering Information
Product name + variant + option codes (if any)
+ circuit condition (if non-standard)
eg:
GWX-38
±20ppm (standard)
GWX-26/A 8.0pF
±15ppm 8.0pF
Option code X (eg GWX-38/X) denotes a custom specification.
IMPORTANT: GWX-38 production will cease Oct 2007. Do not use
GWX-38 for new designs. Use GWX-26 in preference.
