About Power Inductors

Power inductors are fundamental energy storage devices in switching power supplies, temporarily holding current during DC-DC conversion cycles. They smooth output voltage ripple while filtering high-frequency noise – critical for maintaining signal integrity in digital systems. Modern designs prioritize compact footprints, high saturation currents, and EMI shielding to meet shrinking form factors.

Selection requires balancing inductance values, DC resistance, and self-resonant frequency against thermal constraints. Automotive-grade inductors like the LQH3 series withstand extreme temperature fluctuations and mechanical stress, ensuring longevity in electric vehicles, ADAS systems, and industrial automation where component failure is unacceptable.

Packaging Options

Available in industry-standard Tape & Reel (TR), Cut Tape (CT), and Digi-Reel® formats for automated SMT assembly. PCX maintains ready stock across all configurations.

FAQs

Q: Is this inductor suitable for automotive under-hood applications?
A: Yes, its AEC-Q200 qualification and -40°C to +125°C operating range meet automotive requirements.

Q: What’s the difference between saturation current and rated current?
A: Rated current (860mA) is the maximum DC before temperature rise exceeds specs. Saturation current (570mA) is when inductance drops 30% due to core magnetic saturation.

Q: Can I use this for high-frequency switching above 5MHz?
A: Not recommended – self-resonant frequency is 10MHz. Operation near SRF reduces effectiveness.

Q: Does the shielded design require additional isolation?
A: The built-in ferrite shield contains 90%+ magnetic flux, eliminating need for external shielding in most designs.

Q: Are Murata inductors compatible with lead-free reflow processes?
A: Yes, all LQH3 series components support JEDEC-standard reflow profiles up to 260°C peak.

Q: How does tolerance affect power supply performance?
A: ±20% tolerance may require feedback loop adjustments in precision voltage regulators but is acceptable for most DC-DC buck/boost circuits.
