Overview of EPCOS Metallized Polyester Film Capacitors (MKT) Series B32520 B32529

This datasheet provides detailed information on the EPCOS Metallized Polyester Film Capacitors series B32520 B32529, which are designed for general purpose applications, notably in the automotive industry for blocking, coupling/decoupling, bypassing and Radio Frequency Interference (RFI) suppression. Notably, specific models within this series—identified by the ordering codes B3252900335 and B3252900475M—are declared to be withdrawn, with the last order date on 2014-07-15 and the last shipment date on 2014-10-15. Customers are encouraged to contact their nearest EPCOS sales office for assistance in finding suitable substitute products. A link to the worldwide sales network can be found at the EPCOS website.

Key Features and Advantages

The capacitors exhibit high pulse strength and high contact reliability. They are RoHS-compliant and halogen-free options are available upon request. The series features stacked-film technology for lead spacings from 5 to 15 mm and wound capacitor technology for lead spacings from 10 to 37.5 mm. Different types within this series have varying lead spacings and diameters, catering to diverse requirements. Moreover, terminals come with parallel wire leads that are lead-free tinned, and special lead lengths can also be produced based on the customer’s needs.

Product Construction and Specifications

The capacitors are constructed with a dielectric made from polyethylene terephthalate (PET), housed within a plastic case and sealed with epoxy resin, both of which meet UL 94 V-0 standards for flammability. The maxim operating temperature for these capacitors is 125°C, and they fall under climatic category 55/125/56 as per IEC 60068-1. Each capacitor is marked with the manufacturer’s logo, capacitance, tolerance, DC voltage rating, date of manufacture, type, series, and lot number, with variations in marking for lead spacings.

Product Packaging and Compliance

Products in this series can be delivered in bulk or taped (either Ammo pack or reel) depending on the lead spacing, and information regarding taping is detailed in a specified chapter titled “Taping and packing”. Customers are referred to important notes at the end of the document for further information – however, the datasheet prompts users to pay attention to these notes which may contain critical usage and safety information.

It’s also important to note, per the datasheet’s notification, the withdrawal of specific product variants requires customers to plan for a transition to substitute products in a timely manner to avoid any disruption in sourcing these components.
