Humidity Test: Condition networks with no voltage applied for 72 hours
at 95% relative humidity and + 75°C. Remove networks from humidity
chamber, wipe surface dry of moisture and dry in circulating air for
4 hours. Measure insulation resistance at + 25°C and rated DC voltage.
The minimum insulation resistance shall be 5000 Megohm after test.
Not more than one failure in 18 units tested shall be permitted.
AC Operation: The maximum permissible AC voltage to which these
networks may be exposed is 250 volts rms. In no case should the sum
of the DC and peak AC voltage applied to a network exceed the rated
DC voltage.
PERFORMANCE CHARACTERISTICS
Operating Temperature: - 40°C to + 85°C.
Insulation Resistance: When measured at
+ 25°C, the insulation resistance shall exceed
10,000 Megohm. Measurements shall be
made after a 2 minute charge at rated DC
voltage.
Tolerance: Standard tolerance is ± 10% for
both the resistor and capacitor.

Contact Arc Suppression reduces field maintenance, premature equipment
failure and RFI. A capacitor connected across the contacts helps in the
solution of these problems but can cause contact welding and reduced
equipment reliability. By adding a resistor in series with the capacitor, these
additional problems are eliminated.
Because of the increased use of R-C combinations for Arc Suppressors and
snubbers, Sprague® provides low cost Type 288P R-C Arc Suppressors in a
single low profile package.
The standard ratings shown have those combinations of resistance and
capacitance values most commonly required for low power applications.
The standard Type 288P R-C Arc Suppressors consist of a metalized
polyester film capacitor in series with a low value 1/2 watt composition resistor.
These units are supplied with radial leads for quick and easy installation.
The outer covering is a tough, conformal coating of epoxy resin for protection
against heat and moisture. The Arc Suppressors are quite similar in appearance
to the Type 225P Orange Drop® polyester film capacitors.
