What does the label printed on the BM capacitor mean?
There are several types of BM capacitors. Let's illustrate them with a few typical types of printing.
1) AC two-wire type:
BM: Our trademark.
CBB61: Metallized polypropylene film capacitor, square.
4.5uF: the capacity of the capacitor.
± 5%: The tolerance of the capacitor is plus or minus five percent.
350V.AC: The use voltage of the capacitor, 350V AC.
50 / 60Hz: The frequency of the applied voltage is 50 or 60.
-25 ℃ ~ + 70 ℃: The operating temperature of the capacitor is negative 25 degrees to positive 70 degrees.
11.7: Date of capacitor production, July 2011.
: UL certification mark, the number below is the certificate number of BM capacitor UL certification.
2) AC terminals:
SH: The capacitor has a self-healing function. All CBB capacitors are self-healing.
P0: Not explosion-proof.
B: Class B product, can run continuously for 10,000 hours.
40/105/21: It is a product test parameter, which means that the test has been run continuously for 21 days between minus 40 degrees and 105 degrees, and there is no problem with the capacitor.
CQC 08002022577: Passed CQC certification, 08002022577 is the CQC certification certificate number for BM capacitors.
3) Safety regulations:
MKP-X2: Safety capacitor.
K: capacitance tolerance is K level, ± 10%
: The product has passed CUL, VDE, ENEC, CQC certification. IEC60384-14 is the certificate number of BM capacitor.
CBB65: Metallized polypropylene film capacitor, round explosion-proof.
P2: The capacitor is not explosion-proof.
C: C grade product, can run for 3000 hours continuously.
40/85/21: It is a product test parameter, which means that the test has been run continuously for 21 days between minus 40 degrees and 85 degrees, and there is no problem with the capacitor.
Protected 10000AFC: It is the maximum protection current value when the explosion-proof function is enabled.
C22.2 No.190: It is the certificate number of CUL certification.
Polybutene: The packaging material of the capacitor is polyisobutylene.
13.7: The production date of the capacitor is July 2013.
CBB22: Metallized polypropylene film capacitor, encapsulation type.
335J400V: The capacitance is 3.3uF, the tolerance is ± 5%, and the voltage is 400VDC (DC voltage)
Note: Because the value of F (Farad) units is too large, there is a way to express capacity using pF (picofarads) as the unit. The method rule is to use three digits to indicate capacity, the first two digits to indicate the capacity value, and the second digit to indicate the index of 10. For example: 335 means 33 * 10 ^ 5pF = 3300000pF, which is 3.3uF; 224 means 22 * 10 ^ 4pF = 220000pF, which is 0.22uF.
