Overview of EPCOS Film Capacitors
This datasheet provides detailed information about the EPCOS Metallized Polyester Film Capacitors from the MKT Series, particularly the B32520 B32529 models. It states that certain products within this series are being withdrawn, and offers substitute products along with the timeline for the withdrawal process. The substitute products B3252905335* and B3252905474M* replace B3252900335 and B3252900475M*, respectively. The crucial dates include the announcement on April 4, 2014, the last order date of July 15, 2014, and the last shipment date of October 15, 2014. Customers are encouraged to contact their nearest EPCOS sales office for further information and assistance in selecting suitable substitute products.
Applications and Features
The capacitors are used for various general purposes including blocking, coupling, decoupling, bypassing, and RFI handling for automotive applications. These capacitors are recognized for their high pulse strength and high contact reliability, with RoHS-compatible and halogen-free options available upon request. They showcase MTBF of over 100,000 hours, underscoring their reliability in a range of uses.
Capacitor Specifications and Options
Operating at a maximum temperature of 125°C and compliant with IEC 60068-1 (climatic category 55/125/56), these capacitors ensure robust performance under varying conditions. They use dielectric polyester (PET) and are available in two technologies depending on the lead spacing; stacked-film is used for lead spacing between 5 and 15 mm, while wound capacitor technology is applicable for 10 to 37.5 mm spacing. Their construction includes a plastic case and epoxy resin sealing, both complying with UL 94 V-0 standards for safety. Terminals are parallel wire leads, lead-free tinned, and can come in special lengths upon request.
Product Dimensions and Packaging
Capacitors from this series come in different dimensions and lead spacing options ranging from 5.0 mm to 37.5 mm, accommodating various mounting and design requirements. Lead diameters are mostly 0.5 mm, with the data sheet providing a detailed dimensional drawing for reference. Markings on every unit include the manufacturer’s logo, capacitance, tolerance, voltage rating, date of manufacture, coded type, series, and lot number. The capacitors are available either in bulk or taped packaging options, with additional notes on taping and packing provided in a separate chapter.
Important Notice
The datasheet concludes by urging readers to pay attention to important notes at the document’s end, which likely contain safety, regulatory, or usage information pertinent to all users and potential customers.
