SMD Polor Capacitor - English / Hindi

Polority के हिसाब से कैपसिटर दो तरह के होते हैं।
1.     SMD Polorised Capacitor /  Electrolytic  - 

Tantalum Capacitors which is polarized, and may be used in DC circuits. Typical values range form 0.1uF to 470uF.
Standard Tantalum values change in multiples of 10, 22, 33, and 47. Normal Temperature Coefficient [TC] for Tantalum Capacitors is +5%.


Polarized capacitors are typically used in large voltage situations, such as DC line filtering to reduce noise related to uneven voltage levels after rectification from an AC source. Mainly measured in microfarads.




   Polarity is critical to these devices. They are marked with the voltage rating (usually double the circuit voltage used) as well as the farad marking.

ऐसे कैपसिटर जिनमे negative और positive  टर्मिनल होते हैं। Polarized Capacitor कहलाते हैं।


 इन Capacitor को circuit में लगाते समय 

नेगेटिव  पॉजिटिव का विशेष ध्यान रखना पड़ता हैं यदि यह उलटे लगा दिए जाए तो यह गरम होकर फट जाते हैं।










Capacitor work 
कैपसिटर का विभिन्न सर्किट में प्रयोग व् काम
  • ·         कैपसिटर मुख्य काम AC को पास करना  DC को रोकना होता हैं। Pass AC Current And Stop DC Current 
  • ·         यह ख़राब सिग्नल को रिजेक्ट एवं नए सिग्नल को उत्पन करता है Filter bad signals and generate new signals 
  • ·         सिग्नल फ़िल्टर करना l ( Non-Polar Capacitor ) Signal filtration 
  • ·         करंट फ़िल्टर करना एवं करंट को बूस्ट करना  ( Polar Capacitor ) | Filter Current and boost Current
  •   





     
  • Capacitor को C से शो किया जाता है 
  • Circuit Symbol 
  • इसकी इकाई फैरड होती है Unit - Farad
