The **LPCE-651-R** is a specific electronic component primarily categorized as an **Electromagnetic Compatibility (EMC)** solution. It belongs to the family of **Ferrite Sleeves/Cores**, specifically designed for cable management and noise suppression. --- ### 1. Technical Specifications Below are the typical technical characteristics of the LPCE-651-R: | Parameter | Specification | | :--- | :--- | | **Component Type** | Split Ferrite Core (Snap-on) | | **Material** | Ferrite (MnZn or NiZn based) | | **Impedance @ 25MHz** | ~110 Ω (Typical) | | **Impedance @ 100MHz** | ~200 Ω (Typical) | | **Internal Diameter** | ~6.5 mm | | **Outer Dimension** | ~15.0 mm | | **Length** | ~28.0 mm | | **Operating Temperature** | -25°C to +85°C | --- ### 2. Key Features and Construction The "LPCE" series usually refers to "Low Profile Cable EMI" filters. The "651" designates the sizing (6.5mm internal diameter), and the "R" often signifies **RoHS Compliance**. * **Split-Core Design:** The part consists of two halves of a ferrite cylinder housed in a plastic "clam-shell" case. This allows it to be installed on cables that are already terminated with connectors. * **Snap-Mount Mechanism:** It features a locking plastic clip that ensures the two halves of the ferrite are held tightly together around the cable to prevent magnetic flux leakage. * **Broadband Suppression:** It is engineered to provide high impedance over a wide range of frequencies, particularly effective at suppressing High-Frequency (HF) noise. --- ### 3. Primary Applications The LPCE-651-R is used to ensure electronic devices meet EMC compliance standards (like FCC or CE). Common use cases include: 1. **Data Cables:** USB cables, RS-232, and peripheral leads to prevent data corruption from RFI (Radio Frequency Interference). 2. **Power Supplies:** Suppressing switching noise generated by AC/DC adapters. 3. **Industrial Equipment:** Protecting sensitive sensor lines from motor-induced electromagnetic interference. 4. **Medical Devices:** Reducing unwanted emissions to avoid interfering with other sensitive monitoring equipment. --- ### 4. Implementation Example To use this component, you simply snap it over the cable as close to the source of noise (or the entry point of the device) as possible. ```markdown Usage Instructions: 1. Open the plastic housing. 2. Place the cable inside the groove. 3. Snap the housing shut until it clicks. 4. (Optional) For higher impedance, loop the cable through the core twice if the diameter allows. ```
