Product details

Package and temperature grade

Housed in a 165-FBGA (13x15 mm) package, surface mount. The 0 °C to 70 °C commercial temperature range suits indoor rack-mount equipment, telecom line cards, and lab instrumentation — not extended or industrial environments. The fine-pitch BGA demands controlled reflow profiles and X-ray inspection post-assembly.
