Note:
Estimates are made from our tests and manufacturers
data. Conditions are fresh batteries and room temperature. Clad
or ‘‘leak-proof’’ batteries are recommended for any application
of five months or more. Nickel Cadmium cells are not recom-
mended.
APPLICATIONS NOTES
Note 1:
All capacitors shown are electrolytic unless marked otherwise.
Note 2:
Flash rates and frequencies assume a
g
5% capacitor tolerance. Electrolytics may vary
b
20% to
a
100% of their stated value.
Note 3:
Unless noted, measurements above are made with a 1.4V supply, a 25
§
C ambient temperature, and an LED with a forward drop of 1.5V to 1.7V at 1 mA
forward current.
Note 4:
Occasionally a flasher circuit will fail to oscillate due to an LED defect that may be missed because it only reduces light output 10% or so. Such LEDs can
be identified by a large increase in conduction between 0.9V and 1.2V.
