Snap-in Terminal Electrolytic Capacitor
Snap-in terminal, Long life 2000hours
Suitable for Ballast circuit,inverter,transducer.
General Characteristics
1.1 Marking:
Capacitors shall be marked with TOPMAY mark, rated capacitance,
rated DC working voltage
The cathode lead will be identified with minus signs (-) on the side of the case
1.2 Operating Temperature Range:
These capacitors are designed to operate over a temperature range of -25 to
+105ºC
At -40ºCcapacitance shall retain at least 70% of their original 25ºC
measured capacitance. At +105ºC, capacitance shall increase to
no more than 120% of their original 25ºC measured capacitance.
1.3 Vent Test(applies only to those capacitors with vents)
During and after the applicable test below (1.3.1) there shall be no explosion,
flash, flame or expulsion of particles of the core or container
In addition, the case shall not be expelled from the core. lf the capacitor under
test is a multisession unit , this test shall apply to the input section only.
1.3.1 DC test, Capacitors with DC rating volts or less:
Both of the following tests shall be performed, but on separate test units.
1.3.1.1 Forward Bias Test;
The capacitor under test shall be connected to a DC power supply that has sufficient voltage to supply a constant direct current of 500 milliamperes with the positive terminal of the capacitor connected to the positive supply terminal and the negative capacitor terminal connected to the negative supply terminal. The constant current shall be maintained until (1) the capacitor vents, (2)300 seconds have elapsed ,or (3) the capacitor under test open circuits
1.3.1.2 Reverse Bias Test:
The capacitor under test shall be connected to a power supply with sufficient voltage to provide a Constant direct current of 500 milliamperes
when the positive capacitor terminal is connected to the negative supply
terminal and the negative capacitor terminal to the positive supply terminal .The constant current shall be maintained until(1)the capacitor vents, (2)300 seconds have elapsed, or (3) the capacitor open circuits.
