1. Product Overview:

️· Product: FP1005R Series Inductor
️· Type: Shielded Power Inductor
️· Applications: DC-DC conversion, power management in a wide range of electronics (servers, computers, telecom equipment, etc.)
️· RoHS Compliant: Yes

2. Key Features and Specifications:

️· Size: 1005 (1.0mm x 2.5mm x 2.5mm)
️· Inductance Range: 0.8µH to 22µH (Various versions: R3, R4 have different inductance options – see the full table in the datasheet)
️· Rated Current (Irms): Varies based on inductance value (typically up to 8 Amps - check the specifics for each inductance) – derating is required for AC currents
️· Saturation Current (Isat): Varies by inductance (typically around 8-12 Amps; check datasheet).
️· Operating Temperature: -40°C to +125°C (Important: Ensure temperature rise does not exceed 125°C under worst-case conditions).
️· Packaging: Tape and reel, 950 parts per 13" reel.

3. Electrical Characteristics (Important Values):

️· OCL (Open Circuit Inductance): Tested at 100kHz, 0.1Vrms, 0.0Adc, +25°C.
️· FLL (Full Load Inductance): Tested at 100kHz, 0.1Vrms, Isat1, +25°C.
️· K-Factor: Used in calculations of core loss.

4. Part Numbering and Versions:

️· FP1005Rx: Basic part number structure. 'x' is the version indicator. Different versions (R3, R4) have slightly different electrical characteristics.
️· -Rxx: Indicates the inductance value in microhenries (µH), where 'R' is the decimal point.

5. Dimensions & Tolerances:

️· 1.0mm x 0.9mm x 2.5mm.
️· All dimensions are nominal. Tolerances are ±0.25mm unless otherwise specified.

6. Soldering & Reflow Profile:

️· The datasheet provides standard SnPb and Lead-Free solder reflow profiles. Adherence to these profiles is critical for proper soldering. Pay attention to temperature and time parameters.
️· The reflow profile ensures proper solder joint formation without damaging the component.

7. Important Considerations & Warnings:

️· Temperature Rise: PCB layout, trace width, airflow, and proximity of other components significantly impact temperature rise.
️· Derating: AC currents require derating of the rated current.
️· Core Loss: Core loss increases with peak-to-peak ripple current and frequency. The K-factor is essential for calculating Bp-p for core loss.
️· Life Support Policy: The product is not intended for use in life support systems without Eaton's written approval.

8. Core Loss vs. Bp-p and Inductance Characteristics:

️· The datasheet includes graphs that visually display the relationship between core loss, peak flux density (Bp-p), and inductance. It also displays %OCL vs %ISAT.

To effectively use this information:

️· Consult the complete datasheet: This summary provides key information, but the full datasheet contains detailed specifications, graphs, and guidelines.
️· Verify Part Number: Double-check the correct part number for your specific requirements (inductance value, version, etc.).
️· Consider Application Requirements: Factor in operating conditions (temperature, current, frequency) to ensure proper selection and performance.
