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.
