What is MLG1005S39NJT000?
The MLG1005S39NJT000 is a fixed SMD inductor manufactured by TDK. Key specs include a 39 nH inductance, 250 mA rated current, and a 1 Ω maximum DC resistance. RoHS compliant, it is designed for high-frequency circuit impedance matching and noise suppression.
✔ RoHS Compliant / ✔ SMD / ✔ TDK Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- RF Front-End Modules: The 39 nH value (self-resonant frequency in GHz range, typical for MLG series) provides precise impedance matching for LNA or PA stages in cellular and Wi-Fi front ends.
- Bluetooth & Zigbee Antenna Circuits: Its 250 mA current capability easily handles low-power transceiver signals, while the 1 Ω DCR minimizes insertion loss in the narrowband matching network.
- Portable GNSS Receivers: The compact SMD footprint suits space-constrained GPS/Galileo modules; the multilayer construction ensures stable inductance over temperature and frequency.
Key Features & Advantages
- Precise 39 nH Inductance: Tight tolerance (±5% for N-version) ensures consistent circuit performance in production volumes.
- Low 1 Ω DC Resistance: Reduces resistive power loss in signal paths, vital for battery-operated portable devices.
- Multilayer Ceramic Construction: Provides high self-resonant frequency and excellent stability under vibration and thermal stress compared to wire-wound alternatives.
Frequently Asked Questions
- Q: What makes MLG1005S39NJT000 different from a standard 39 nH wire-wound inductor?
A: As a multilayer chip inductor, it offers much higher self-resonant frequency (typically above 1.5 GHz) and negligible EMI shielding issues, making it ideal for RF rather than power applications. - Q: Is MLG1005S39NJT000 RoHS compliant?
A: Yes, as a TDK product, it is standardly RoHS compliant and lead-free per EU Directive 2011/65/EU. - Q: What is the MOQ?
A: We support small batch orders and full BOM kitting at SZYY.
