28 MHz GBW, 50 V/µs slew rate — JFET input in a hermetic can
The 5962-8770602GA is a single-channel JFET-input operational amplifier from the 5962-87706 series, packaged in a hermetic TO-99-8 metal can.
Hermetic TO-99-8 — built for sealed, high-reliability deployments
The TO-99-8 metal can package is a through-hole, hermetically sealed enclosure. It is designed for environments where moisture, outgassing, or mechanical shock would compromise a plastic package — avionics, satellite payloads, missile guidance, and downhole instrumentation. The metal can also provides a degree of RF shielding.
For a military-temperature, hermetic JFET op-amp, this is a stable sourcing position — no urgency to stockpile or qualify a substitute.
