Overview
IEC 60384-14-2:2025 is an international standard developed by the International Electrotechnical Commission (IEC) that provides a blank detail specification for fixed capacitors used in electronic equipment, specifically for electromagnetic interference (EMI) suppression and for connection to supply mains. This standard focuses solely on safety tests and forms the basis for a common international safety mark for these capacitors. It sets out a uniform procedure for safety test approvals as defined in IEC 60384-14, as well as parameters relevant to design safety and requirements for conformance and requalification testing for each lot of components.
This edition incorporates significant updates, notably replacing dimensional tables with guidance text and adding requirements for DC applications and high humidity conditions. IEC 60384-14-2:2025 is intended for use alongside IEC 60384-1:2021 and IEC 60384-14:2023.
Key Topics
-
Scope
Focuses on blank detail specifications for fixed capacitors and resistor-capacitor combinations requiring only safety testing for use in electronics. It is essential for drafting detail specifications that target safety compliance for EMI suppression capacitors connected to power supplies.
-
Safety-Related Design Declaration
Specifies processes for manufacturers to declare key safety-relevant design parameters, which are confidential between the manufacturer and certification body.
-
Testing Requirements
- Initial Approval: Sets the baseline safety inspection and testing prior to product release.
- Conformance Testing: Mandates safety conformity checks on every manufacturing lot.
- Requalification: Outlines procedures for requalifying products when essential design changes occur.
-
New Technical Changes
- Guidance replaces fixed tables for dimensions, allowing more flexibility and clarity for manufacturers.
- Additional requirements for capacitors intended for DC service and high humidity environments, ensuring reliability under diverse conditions.
- Cross-references to changes from the previous edition are provided for clarity.
-
Information for End Users and Purchasers
The specification indicates what ordering and marking information should be supplied for clear identification and traceability.
Applications
IEC 60384-14-2:2025 is widely applicable in industries where electronic equipment must comply with international safety standards for EMI suppression, such as:
- Consumer Electronics: Ensuring capacitors used in devices connected directly to supply mains meet rigorous international safety standards.
- Industrial Control Systems: Supporting system integrators and OEMs in selecting capacitors with verified EMI suppression performance and safety.
- Home Appliances and Power Supplies: Guaranteeing components used in AC or DC supply connections conform to necessary safety and durability criteria.
- DC and High Humidity Environments: Covering new scenarios where capacitors must operate reliably under challenging environmental conditions.
By aligning with IEC 60384-14-2:2025, manufacturers and certification bodies can ensure products consistently meet global safety expectations-minimizing risk for device manufacturers, integrators, and end-users.
