Overview
The Murata EKEM13UC is a chip ferrite bead sample kit featuring components from the BLM series. Murata Manufacturing’s chip ferrite beads are inductor-type EMI suppression filters effective at low to high frequencies. This sample kit is ideal for design engineers and technicians evaluating ferrite bead solutions for noise suppression in electronic circuits.
Key Features
- BLM series ferrite beads are designed for power supply circuits that require high-rated current and suitable for suppressing high-frequency noise over a wide frequency range in power supply circuits.
- The BLM series are effective in circuits without stable ground lines because it does not need a grounding connection.
- The nickel barrier structure of the external electrodes provides excellent solder heat resistance.
- The BLM series can be used in high-current circuits due to its low DC resistance and can match power lines to a maximum of 20 A-DC while offering effective noise suppression across a wide frequency range.
- Murata’s BLM EMIFIL chip ferrite beads offer AEC-Q200-certified products for automotive applications such as infotainment and powertrain safety applications.
Technical Specifications
As a sample kit, the EKEM13UC includes multiple ferrite bead component options from the BLM series for evaluation purposes. Typical BLM series specifications include operating temperature ranges from -55 to +125°C and rated currents ranging from 200 mA to 20 A depending on the specific component included in the sample set.
Typical Applications
- Power supply circuit noise suppression
- Automotive infotainment systems
- Powertrain safety equipment
