Product Description
The ETQ-P5M4R7YFM is a specialized high-current power inductor designed for demanding industrial and automotive applications.
Core Functionalities
- Energy Storage & Filtering - Designed for DC-DC converters and switching power supplies with 4.7 µH inductance (4R7 = 4.7 µH) for smoothing current ripple in high-frequency circuits.
- Rugged Construction - 5mm x 5mm x 3mm surface-mount package with metal composite core and epoxy coating for vibration, moisture, and thermal stress resistance (-40°C to +125°C).
- EMI Suppression - Reduces electromagnetic interference (EMI) in sensitive systems for compliance with CISPR 22 Class A/B standards.
- Saturation Resistance - Maintains inductance stability under heavy loads with saturation current exceeding 7A for reliable performance.
Typical Applications
- Automotive Electronics - DC-DC converters for infotainment systems, ADAS sensors, and EV auxiliary circuits; engine control units (ECUs).
- Industrial Automation - Motor drives for pumps, compressors, and robotics; renewable energy systems.
- Consumer Electronics - Fast-charging adapters (140W+ output) and gaming console power filtering.
- Aerospace & Defense - Avionics systems meeting MIL-STD-810H for shock and vibration resistance.
Technical Specifications
- Inductance: 4.7 µH (±20% tolerance)
- Current Rating: 5A (continuous), 7A (saturation)
- DC Resistance (DCR): ≤15 mΩ
- Operating Temperature: -40°C to +125°C
- Package: 5mm x 5mm x 3mm SMD (IPC 7351 Type 5)
- Termination: Tin-lead (Sn-Pb) or lead-free (RoHS-compliant) finish
- Shielding: Optional magnetic shielding to reduce EMI
Key Considerations
- The "YFM" suffix may denote customized features - always consult manufacturer's datasheet for exact parameters
- Analogous to TDK's B82481A470M (4.7 µH, 5A) and Murata's LQP15MN4R7M02D (4.7 µH, 4A)
- Pair with low-ESR capacitors for optimal ripple reduction
- Likely compliant with AEC-Q200 Grade 1 (automotive) and UL 94V-0 flammability standards
