Type 288P
Vishay Sprague
R-C Arc Suppressors
ORANGE DROP
®
, Radial Lead
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.
PERFORMANCE CHARACTERISTICS
Operating Temperature:
- 40 °C to + 85 °C
Insulation Resistance:
When measured at + 25 °C, the
insulation resistance shall exceed 10000 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.
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.
