1. Product Information & Core Combinations:

️· The document details ferrite core products, specifying their suitability for various applications.
️· There are four core types described (N49, N92, N87, N97).
️· The document includes tables outlining key specifications for each core type, including:
- A value (L) in nH
- µ (initial permeability)
- P (power loss) in W/set
- Ordering codes (ELP and I core variations)
️· The core combinations described use the ordering codes ELP and I.

2. Mechanical and Handling Cautions:

️· Ferrite Brittleness: Ferrite cores are brittle and sensitive to shock, rapid temperature changes, tensile loads, and ultrasonic cleaning.
️· Stress and Magnetic Properties: Stresses on the core affect the initial permeability; embedding materials should be elastic.
️· Heating: Ferrites can generate heat at higher flux densities and frequencies.
️· NiZn-Materials: NiZn ferrites can have irreversible changes in magnetic properties in high magnetic fields.

3. Processing Notes:

️· Winding processes must be gentle to prevent damage.
️· Excessive winding force should be avoided.
️· Soldering times at high temperatures should be minimized.
️· Proper pin arrangement and hole diameter must be followed in printed circuit boards.

4. Important Notes & Disclaimer:

️· Suitability: EPCOS's suitability statements about products are not binding and customers must ensure product suitability.
️· Failures: Malfunctions are possible, and customers must design accordingly, especially in safety-critical applications.
️· Compliance: Customers should review the Material Data Sheets for information on restricted substances.
