Brand: Standard / SPIRIT
Place of Origin: Xiamen, China
Type: metallized film polypropylene capacitor (no polarity does not distinguish between positive and negative)
Specification: 3.3μF 250V
【use】
  ①The role of high resistance and low resistance. Components that can be used to make frequency dividers
  ②Simple frequency division of speaker tweeter / car tweeter speaker filtering
 
[Notes on use]
  ① When dividing the treble, the string is on the positive pole of the tweeter
  ② The capacitor is electrodeless, and the wiring itself does not need to distinguish between positive and negative
  ③When used as a frequency divider, if a frequency divider has been used, there is no need to connect a capacitor to the treble. Choose one of the capacitor and the frequency divider.
【Recommendation】
  ① The car tweeter or speaker tweeter (tweeter + bass two-way speaker) generally uses a capacitor of about 3.3, usage
     The tweeter and woofer are connected in parallel, and the positive string of the tweeter is connected to the capacitor, and the woofer is not used;
 
  ② If you do n’t want to use a frequency divider for the three-way speaker, you need to use a capacitor of about 3.3 for the tweeter.
     The midrange uses a capacitor of about 12, no bass, there is no standard match for the capacitor three-way frequency, and the parameters of the speaker and personal preferences
     Related, you need to try and adjust.
 
     Theoretically, the larger the capacitance, the lower the filtered bass band, and the lower the crossover point

  ①What is MKP?
       MKP is a metalized polypropylene film capacitor (Metalized Polypropylene Film Capacitor), metallization means that the aluminum electrode is not a thin film, but evaporated aluminum foil. Compared with ordinary CBB capacitors, MKP has a high withstand voltage starting point, low loss, low internal temperature rise, negative capacitance temperature coefficient, and excellent flame retardant performance.
 
  ②Why use capacitor?
       The treble in the crossover speaker must be divided, that is, the low frequency is considered, and the low frequency is prevented from entering the tweeter, otherwise the tweeter will be 100% burned out (the woofer may not be divided and will not burn)!
 
  ③What is the difference between capacitor and frequency divider?
       The frequency divider can use a frequency divider, or a capacitor to simply divide the frequency, choose one of the two, you do n’t need to use it. The sound quality of capacitor frequency division depends on the quality of the capacitor, and the sound of a good capacitor is clearer and more detailed. This capacitor is a genuine spirit product, the conventional 2.2-6.8uF (the specific value depends on the speaker design, speaker quality and personal needs) is suitable for two-frequency treble frequency division, the effect is very good.
 
     Capacitor frequency division and crossover frequency division have their own advantages and disadvantages: because only one capacitor is used, the signal loss is less, and the sound is larger than that of the crossover, but the capacitor only divides the high frequency, and the woofer does not Unfiltered waves, so the sound from the woofer will be more ambiguous than the sound from the crossover. If the ear is not very picky, you can choose capacitor frequency division, saving cost and easy to install.
