Meeting EMC requirements is critical and TDK-Lambda EMI filters provide a reliable solution

Complying with EMC standards

Challenges

EMC compliance testing is one of the last stages in a project’s development. Exceeding EMI limits or failing immunity surge testing can result in delays to your schedule, require safety re-certification resulting in cost increases.

Our Solutions

The R series of EMI and EMC filters offers a vast range of package styles, current ratings and input voltages. Our filters with surge suppression use TDK’s amorphous core technology with a higher resistance to saturation from high voltage pulses and greater long-term reliability.

Class A/B EMI

Challenges

High Speed and High frequency devices are everywhere in the electronics. A System with poor EMC performance may interfere with the operation of the sensitive equipment. Even though the power supply claims Class A or B level EMC performance, at the system level it may fail to comply.

Our Solutions

We offer a large number of package styles, current ratings and input voltages including filters with surge suppression that use TDK’s amorphous core technology with a higher resistance to saturation from high voltage pulses and greater long-term reliability.

Generate Noise/Susceptible against the external Noise

Challenges

Understanding the type of electrical noise is crucial to avoid malfunction of a system. There are basically three types of noise - internally generated noise, external man-made noise and noise generated by nature such as lightning surge or solar storms.

Our Solutions

The R series of EMI filters offers not only a huge range of package styles, current ratings and input voltages, but also a choice of Ferrite or Amorphous core inductors used in the noise filter. Amorphous core inductors have higher saturation levels than ferrite and will suppress pulse noise generated by external equipment such as Laser and welding machines. These noise surge pulses will often cause malfunction of the system. TDK’s amorphous core technology with a higher resistance to saturation from high voltage pulses offer greater long-term reliability.

UL508A Safety Certification

Challenges

UL508A 2020 revision added SCCR (Short Circuit Current Rating) for EMI filters.

Our Solutions

EMC filters with SCCR ratings may shorten the time and cost for UL508A safety certification. TDK-Lambda offers EMI filters with safety certified SCCR rating - see our EMI filter brochure below for more details.

Medical EMI Filters

Challenges

Meeting EMC in medical devices is especially important as a malfunction can have dire consequences. Often these devices are in high noise environments generated by MRI scanners or other equipment or appliances, particularly in home healthcare.
Global medical certifications such as UL/EN/IEC 60601-1 and CISPR 11 are designed to limit interference to protect patients.

Our Solutions

The R series of EMI filters offers medical EMI filters with low AC leakage currents, ideal for medical devices.
