About These Specifications
Maximum and minimum specifications are warranted not to exceed these values within certain operating conditions and include the effects of temperature and uncertainty unless otherwise noted.
Typical specifications are unwarranted values that are representative of a majority (90%) of units within certain operating conditions and include the effects of temperature and uncertainty unless otherwise noted.
Characteristic specifications are unwarranted values that are representative of an average unit operating at room temperature.
All specifications are characteristic unless otherwise specified.
Nominal specifications are unwarranted values that are relevant to the use of the product and convey the expected performance of the product.

Estimating Reed Relay Life
- Determine the peak voltage experienced across the relay while switching and mark this value on the Volts line.
- Determine the sum of the DUT, cable, and instrumentation capacitances and mark this value on the Load Capacitance line.
-
Draw a straight line between both values.
The intersection points of this line and the No Protection and 50 Ω Protection axes are the corresponding estimated relay lifetimes in cycles.
Estimating Reed Relay Life Example
The reed relay module is connected to a DMM through 1 meter of cable. The DMM and cable capacitances are 100 pF and 30 pF respectively. The maximum voltage switched across the relay is 50 V. Determine the estimated number of relay cycles with and without protection resistance.
Solution
The total load capacitance is the sum of the cable and DMM capacitance, which is 130 pF. Draw a line between the 50 V point on the Volts axis and 130 pF on the Load Capacitance axis.
The line drawn intersects the Cycles axes at approximately 500,000 on the No Protection axis and about 25,000,000 on the 50 Ω Protection axis, as shown in the following figure. This series resistance should be placed as close as possible to the relay for maximum effect.
