Some things you have to be sure of... Can you guarantee the LEDS are DRY when you receive them ? They may be packed in dry bags but when was this done and has the LED distributor had them open at his site ? Using vacuum sealed dry packs is a good way

The low value will be 0.624uF. You have to factor it from the low tolerance (-10%). So: 0.9 x 0.92 (machine tolerance) x 0.91 x 0.91 x 0.91 (3 decade aging factor for X7R dielectric). We factor hours at the 3rd decade (10,000 hours), but you can
