Overview of EPCOS Metallized Polyester Film Capacitors (MKT) Series B32520 B32529
The datasheet provides technical information about the EPCOS Metallized Polyester Film Capacitors, specifically the B32520 and B32529 series, designed for general-purpose applications in the electronics industry. Released in August 2004 by EPCOS AG, this document is essential for engineers and buyers looking to understand the specifications and potential applications of these components.
Applications
The capacitors in the B32520 and B32529 series are suitable for various electronic functions, including blocking, coupling and decoupling, bypassing, and RFI suppression, especially in automotive contexts.
Construction and Features
These capacitors are made of polyethylene terephthalate (PET) using stacked-film technology, which is ideal for lead spacings between 5 to 15 mm. For wider lead spacings of 10 to 27.5 mm, the wound capacitor technology is employed. The devices are encased in plastic with a UL 94 V-0 rating, ensuring a high level of safety by means of flame-retardant material, and sealed with epoxy resin with the same flammability standard.
The series exhibits high pulse strength and contact reliability. The capacitors can operate at a maximum temperature of 125°C and adhere to the climatic category 55/125/56 as per IEC 60068-1 standards, signifying their robustness in various environmental conditions.
Specifications
The dimensions of the capacitors vary based on type, with detailed dimensional drawings available in the datasheet. Lead diameters also vary, ranging from 0.5 mm to 0.8 mm, corresponding to the type of capacitor. Specific types are denoted using a coding system where codes N, Q, or T represent the construction technology used.
Marking and Delivery
Each capacitor is marked with the manufacturer’s logo, capacitance value, capacitance tolerance, rated DC voltage, date of manufacture, and type/series codes for easy identification. They are available in bulk or in taped formats like Ammo pack or reel, with additional information on taping available in another chapter of the datasheet.
Note on Reproduction
Reproduction, publication, dissemination, or use of the datasheet and the contained information without express written consent from EPCOS AG is strictly prohibited. Purchase orders for these products are subject to standard conditions recommended by the ZVEI German Electrical and Electronic Manufacturers’ Association unless an alternative agreement is in place.
