High Temperature Film Capacitorfor Automotive Application

Product catalog summary

Overview: The document outlines the development and specifications of high-temperature film capacitors by Murata Manufacturing Co., Ltd., tailored for automotive applications that demand high heat resistance and safety. These capacitors are ideal for electric vehicles (EV), hybrid electric vehicles (HEV), plug-in hybrid electric vehicles (PHEV), and fuel cell electric vehicles (FCEV).

Conventional vs. High-Temperature Capacitors: Conventional film capacitors are typically used for smoothing capacitors in xEV power electronics, with a continuous use guarantee at 105°C. They have limited self-healing capabilities at high temperatures, which can result in short mode failures. In contrast, the new high-temperature capacitors can operate continuously at 125°C and feature functional self-healing at high temperatures, leading to open mode failures.

Specifications: The high-temperature film capacitors are available with rated capacitances of 10, 15, and 20µF, and a rated voltage of 500Vdc. They are designed for an operational life of 2000 hours at 125°C/500Vdc and can endure biased humidity conditions of 85°C/85%RH/500Vdc for 1000 hours.

Applications: These capacitors are suitable for use in electric compressors, on-board chargers (OBC), and wireless power transfer systems (WPT) in automotive applications, contributing to high power density and reliability in high-temperature environments.

Material and Performance: The capacitors utilize a new high heat-resistant dielectric material, allowing for higher permissible ripple currents under high-temperature conditions compared to conventional polypropylene (PP) film capacitors, which is particularly beneficial in high-frequency applications.

Design Considerations: The document stresses the importance of adhering to ratings and cautions related to storage, operating conditions, soldering, mounting, and handling to prevent issues such as smoking or burning. It also notes that specifications are subject to change and advises consulting with sales representatives or product engineers before ordering.

Export Control and Reliability: The document includes export control information, specifying that Murata products should not be used for military applications or in high-reliability applications without prior consultation. It also highlights that no ozone-depleting substances are used in the manufacturing process.
