Frequently Asked Questions
What package style is this op-amp housed in?
This part is housed in an 8-lead TO-99 hermetic metal can package with radial gold-plated through-hole leads and a pin 8 alignment tab.
What markings are stamped on the component?
The top face of the metal can is stamped with the marking 318. No additional manufacturer logos or date codes appear on the body.
Why buy individual components instead of a bulk surplus lot?
Buying exact counts avoids paying for excess parts or untracked surplus lots when only a few pieces are needed for a repair or build. More pieces cost less each, and the price-break table on this page shows what each quantity costs. Orders ship for an $8 flat rate, or free once the order passes $28, leaving our Idaho warehouse the same or next business day.
Hermetic metal cans from the golden age of analog design deliver a level of durability modern plastic packages rarely touch. Drop this 318 into your circuit and let the analog signal flow the way it was designed to.
