Typical Applications & Why This Part Fits

• High‑Frequency RF Front‑Ends: Its 1.2 nH inductance ensures precise resonance in GSM/WLAN band‑pass filters, while 1 A current handling supports power amplifier stages.
• DC‑DC Converter Output Filters: The low 90 mΩ DCR minimizes conduction losses, enabling >90% efficiency in 1 A boost or buck converters for IoT modules.
• Signal Integrity in 5G mmWave Modules: Ultra‑low inductance and miniature SMD footprint reduce parasitic capacitance, preserving signal quality at frequencies above 2 GHz.

Key Features & Advantages

• Low DC Resistance (90 mΩ): Reduces I²R power dissipation, allowing continuous 1 A current without excessive heat in compact designs.
• High Saturation Current (1 A): Maintains inductance stability under full load, crucial for digital power management in base stations and edge computing.
• Monolithic Ceramic Construction: Provides excellent Q‑factor and self‑resonant frequency (SRF > 10 GHz), enabling stable operation across wide temperature ranges.

Frequently Asked Questions

1. Q: What makes LQG15HS1N2S02D different from a standard wire‑wound chip inductor?
   A: Its monolithic ceramic structure yields superior high‑frequency performance with SRF > 10 GHz, whereas wire‑wound inductors often exhibit lower SRF and higher parasitic capacitance.
2. Q: Is LQG15HS1N2S02D RoHS compliant?
   A: Yes, as a muRata product, it is standardly RoHS compliant and lead‑free, per the manufacturer’s current environmental compliance.
3. Q: What is the recommended reflow profile for this part?
   A: MuRata recommends a reflow peak temperature of 260 °C (10 s max) with a ramp‑up rate ≤ 2 °C/s. We can provide exact profile guidelines upon request.
