Description
1:Model Decoding:
B41252: TDK/EPCOS series code for shielded wire-wound inductors for power applications.
9827: Key parameter code. 98 indicates an inductance value of 820 nH, while 27 may represent tolerance or special characteristics.
M000: Typically denotes tape-and-reel packaging and specific version codes.
2:Electrical Parameters:
Inductance (L): 820 nH (±10%).
Saturation Current (Isat): 7.8 A
Definition: The current at which inductance drops to a specific percentage (usually 10% or 30%) of its initial value. A critical metric for evaluating the inductor’s ability to prevent core saturation in power applications.
Thermal Current (Irms): 9.5 A
*Definition: The maximum continuous DC current based on the component’s self-temperature rise (typically 40°C or 55°C). Exceeding this current may cause overheating and potential damage.*
3:Construction & Materials:
Core Type: Ferrite core, offering high permeability and excellent electromagnetic shielding.
Structure: Shielded construction (typically molded or magnetically shielded), effectively suppressing electromagnetic interference (EMI) while providing mechanical protection.
Terminals: Excellent solderability, suitable for reflow soldering processes.
4:Operating Conditions & Certifications:
Operating Temperature Range: -55°C to +150°C
The wide temperature range ensures stability in harsh environments, particularly in automotive engine compartments.
Certifications & Standards:
AEC-Q200 Qualified: Meets the stringent reliability requirements of the automotive industry.
RoHS Compliant: Lead-free and environmentally compliant.
5:Primary Applications:
Automotive Electronics: Its primary market. Commonly used in:
Engine Control Units (ECUs)
Advanced Driver Assistance Systems (ADAS)
Infotainment Systems
Power Management ICs (PMICs)
Energy storage and filtering in DC-DC converters
Industrial Equipment: Ideal for industrial power supplies and control systems requiring high reliability and temperature stability.
Telecommunications Infrastructure: Used in power modules for servers, base stations, and other equipment.
