10V reference, 3458A calibration.

[fcb]

We are releasing a small batch of our 389-2 10V reference.  Now calibrated using our 3458A.

Here's the original datasheet: https://downloads.electron.plus/manuals/previous/389-2_summary_1Jan18.pdf, and userguide: https://downloads.electron.plus/manuals/previous/389-2_userguide_1Jan18.pdf

We are only releasing this batch to mainland UK customers (for shipping reasons!): £48 incl. VAT, calibration & shipping - we haven't put them on the main site yet and they won't be that price either, if you'd like one then drop me an email: sales@electron.plus.

Is that LT1021 in epoxy packages?

[fcb]

Yes, the LT1021.  We assemble, then bake them for 24/48hrs, then they are coated with quite a few layers of silicone to help stabilise the humidity.  We started making these in 2015 and make occasional batches.  We have some left from the most recent batch.  And we are revamping the casing (adding custom labels and some other bits), so these will be the last of this model number.  The replacement will be higher priced.

Is there any info on long term drift. What level of performance can be expected?

[fcb]

Across a group of these over the last 5 years, overall 'drift' has been between 3ppm and 16ppm.
