EMI-RFI Filters Catalog

Product catalog summary
Overview: This document is a comprehensive product catalog from Exxelia Technologies, focusing on EMI-RFI miniature filters. These filters are designed to attenuate specific electrical frequencies and protect electronic equipment from interference. The catalog includes various types of filters such as low-pass, C, L, Pi, T, 2xPi, 2xL, and 2xT cells.
General Information: Filters are devices used to reduce certain electrical frequencies, primarily aimed at protecting electronic equipment from interference. The catalog provides guidance for designers in selecting and using Exxelia Technologies filters.
Filter Types and Specifications: The catalog lists various filter types, including solder type filters (Ø 3 mm), screw type filters (Ø 3 mm to Ø 17 mm), and surface mount filters (3 to 10 mm). Each type is available in different cell configurations (C, L, Pi, T) and is designed for specific applications, including space applications conforming to standards like AIR 2021 E or EN 2282.
Manufacturing and Inspection: Details on the manufacturing and inspection processes for the filters are provided, ensuring quality and compliance with industry standards.
Certifications: The company is ISO 9001 certified, ensuring quality management standards are met.
Role of Protective Filters in Modern Electronics: Filters are essential in limiting interference and ensuring electromagnetic compatibility (EMC) between disturbing and susceptible elements. Disturbing elements include power control devices and automation equipment, while susceptible elements are often semiconductor devices and sensitive measurement systems.
Types of Filter Architectures: The document describes four main types of low-pass filter architectures: Capacitive Filters, L Filters, T Filters, and Pi Filters, each offering different levels of attenuation and suitable for various impedance applications.
Filter Characteristics and Applications: The document discusses the importance of input and output impedances in determining the quality factor of a filter and its suitability for specific circuits.
Technology and Characteristics of EXXELIA Filters: Details on the components, mounting, and general characteristics of EXXELIA filters are provided.
Measurement and Selection Methods: Methods for measuring filter performance and selecting appropriate filters for specific impedance conditions are outlined.
Installation and Standards Compliance: Guidance on mounting and connecting filters, as well as compliance with standards such as AIR 2021 E, EN 2282, and AIR 7305, is included.
Electromagnetic Compatibility: The document emphasizes the role of filters in achieving EMC by reducing interference through active and passive protection methods.
Specifications and Standards: The document outlines the specifications for filters used in high impedance circuits, emphasizing a 60 dB/decade attenuation. It references the MIL STD 220 C standard, which specifies methods for measuring the performance of passive, low-pass EMI/RFI filters.
Measurement Principles: The standard measures insertion loss, considering frequency, temperature, and direct current bias. Filters are typically feed-through types, designed for bulkhead mounting.
Filter Structure Selection: Selection is based on desired attenuation at the lowest frequency, source and load impedance, and possible attenuation slopes from the cutoff frequency (Fc).
Technology and Characteristics: Exxelia Technologies filters use ceramic dielectrics conforming to NF/MIL standards. Inductors are selected based on physical dimensions and electrical characteristics, using ferrites or wound toroids.
Filter Selection Method: Filter selection depends on application fields (e.g., military, aerospace), circuit characteristics (voltage, current), environmental conditions, and the type of signal to be filtered.
Environmental Conditions and Signal Type: Environmental factors such as temperature and corrosive atmospheres influence filter choice. Filters should not alter the signal pass band, and most Exxelia filters provide over 70 dB attenuation.
Mounting and Connections: For effective performance, the filter case must share the same ground reference as the equipment. Proper mounting instructions must be followed to avoid performance degradation.
Filters Conforming to Standards: The document outlines the standards AIR 2021 E or EN 2282, which define compatibility conditions for in-flight and ground generators, interfaces, and equipment.
RoHS Leaded Components: Most filters are available in RoHS-compliant versions, marked with a 'W' label, adhering to the 2002/95/CE regulation.
Solder Type Filters: Various types such as C, L, and Pi are described with specific characteristics and applications.
Screw Type Filters: Utilizes multilayer ceramic discoidal capacitors with silver metal housing and resin sealing.
General Characteristics: Rated voltage ranges from 50 to 1000 VDC and 115 to 250 Vrms. The test voltage is twice the rated voltage (2 x UR), except for specific cases where it is 1.25 x UR.
Working Conditions: The operational temperature range is from -55°C to 125°C.
Mounting Precautions: Soldering should be performed at a temperature of 275°C ± 5°C for a duration of 6 seconds.
Marking: Components are marked with EFD, type of unit, data sheet reference, rated voltage, date-code (year-month), and circuit of the unit.
Reliability and Specific Versions: Reliability models and specific versions are available upon request.
Conformity: Products conform to AIR 2021 E or EN 2282 standards, with RoHS compliance indicated by 'W'.
Thread Specifications: Thread types include ISO (M 10 x 0.75) and ASA (Ø 5/16 - 24 UNF) with specific dimensions for each.
Filter Types: Various filter types are available, including L, Pi, and T configurations, each with specific characteristics and applications.
Ordering Information: Ordering codes include details such as RoHS compliance, rated voltage, thread type, diameter, and filter type.
Capacitance Values and Codes: Capacitance values range from 1000 pF to 220 nF, with corresponding codes provided for each value.
Technology and Applications: Exxelia Technologies manufactures miniature EMI filters using ceramic capacitors and ferrite inductors. These filters are known for high reliability and performance, meeting ESCC requirements and being referenced in ESA EPPL.
Specifications: Four types of cells are proposed for space applications: C, L, Pi, and T, all with a diameter of 35mm.
Filters and EMC Protections: Exxelia Technologies provides a wide range of filters and EMC protections for applications such as high power, ancillary circuits, small signals, TEMPEST for secure communications, and NEMP-HA for protecting electronics from high-altitude nuclear explosions.
Contact Information: Headquarters and plant addresses in France are provided, along with contact details for further inquiries.

General information Généralités 1.3. Propagation media The mains supply grid may conduct high level parasites at high frequency which easily by-pass transformers or rectifier circuits, and remain harmful. Le réseau de distribution électrique « secteur » peut conduire des parasites de haut niveau et de fréquence élevée qui franchiront facilement les transformateurs, les circuits de redressement, sans perdre de façon notable leur nocivité. Due to their function these circuits are the most sensitive to interference by parasites. They are made to receive signals which may be of various origins and...
