Overview
The datasheet provides detailed information on EPCOS metallized polyester film capacitors, part of the B32520 and B32529 series. These capacitors are designed for general-purpose applications with options for customization and various mounting styles. The document outlines technical specifications, operational guidelines, and product withdrawal and substitution details for certain models.
Product Withdrawal
Note is made that specific products detailed within this datasheet (B3252900335 and B3252900475M) are set to be withdrawn. Substitutes (B3252905335* and B3252905474M*) have been suggested, with an effective withdrawal date of April 4, 2014. The last opportunity to order these components was July 15, 2014, with a final shipment deadline of October 15, 2014. Customers are encouraged to contact their nearest EPCOS sales office for alternative solutions and further assistance.
Applications and Features
These capacitors are used in applications such as blocking, coupling, decoupling, bypassing, and RFI tasks within the automotive industry. As premium electrical components, they offer high pulse strength, high contact reliability, and compliance with RoHS standards. Halogen-free variants are available upon request.
Construction and Specifications
These capacitors employ a dielectric made from polyethylene terephthalate and come in two technological variants: stacked-film for lead spacing of 5 to 15 mm, and wound capacitor for lead spacing of 10 to 37.5 mm. They are encapsulated within a plastic case and sealed with epoxy resin, both rated at UL 94 V-0 for safety. Various lead spacings and diameters are available, specified in the datasheet, to cater to different electrical and physical design requirements.
Marking and Ordering
Each capacitor is marked with the manufacturer’s logo, capacitance, tolerance, rated DC voltage, date of manufacture, series, and lot number. For lead spacings greater than or equal to 10 mm, additional coded type is indicated. Capacitors are sold both in bulk and in taped form, facilitating different assembly methods such as ammo pack or reel.
Additional Information
A dimensional drawing is provided along with a chart that specifies the dimensions for various lead spacings and diameters. It is imperative for users to read the ‘Important notes’ section provided at the end of the document for comprehensive instructions and safety guidelines related to the use and handling of these products.
The datasheet exhaustively compiles the technical details across 45 pages, but it is crucial that one contacts EPCOS directly for the most current product information, especially considering the withdrawal dates mentioned.
