Main Electrical and Physical Characteristics of the LQG15HS2N2B02D Murata Electronics Surface Mount Inductor

The LQG15HS2N2B02D Murata Electronics SMD Inductor is defined by the following critical parameters:

Inductance: 2.2 nH (nominal)

Maximum Rated DC Current: 900 mA

Maximum DC Resistance: 90 mΩ

Form Factor: 0402 (1005 metric, thin profile)

Unit Mass: approximately 0.001 g

The device is unshielded and constructed with multilayer technology, balancing small size with consistent electrical performance. Its current handling capability—up to 900 mA—supports high-frequency and power integrity applications, while the low DC resistance minimizes insertion loss and enhances overall efficiency in RF and signal-line filtering circuits.

Electrical performance is assured through compliance with standardized test methods, and all ratings are specified for performance under conditions such as glass-epoxy substrate mounting, as recommended by Murata.

Guidelines for Placement and Soldering of the LQG15HS2N2B02D Murata Electronics Surface Mount Inductor

The LQG15HS2N2B02D Murata Electronics SMD Inductor is intended exclusively for assembly via reflow soldering methods. Key considerations for installation include:

Adhering to specified land dimensions, soldering materials, and thermal profiles to avoid thermal shock, solder joint cracking, or electrical degradation.

Ensuring that inrush or surge currents in the application do not exceed rated limits to prevent internal damage or catastrophic failure such as fusing or overheating.

Mechanical layout design should minimize exposure to flexing, board bending, or stress concentrations around the mounted inductor—especially near board breaks or screw fittings.

Avoid excessive solder volume which may induce mechanical stress and compromise electrical reliability; this is particularly critical in high-density layouts.

Cleaning procedures must respect maximum allowable temperatures (60°C for general, 40°C with IPA) and preclude aggressive solvents. When using resin encapsulants, perform qualification tests to avoid interaction-induced failures.

Murata further recommends evaluating the inductor in the final application context to confirm compatibility with customer specifications and end-use conditions.

Environmental Suitability and Reliability Aspects of the LQG15HS2N2B02D Murata Electronics Surface Mount Inductor

To maintain long-term reliability and electrical performance, the LQG15HS2N2B02D Murata Electronics SMD Inductor must be operated within its specified environmental limits:

Avoid exposure to corrosive atmospheres (e.g., chemical vapors, chloride, sulfur compounds) and situations where condensation or liquid ingress is likely.

When installed near heat-generating devices, ensure adequate thermal management so that the device’s ambient and substrate temperature remain within rated maximums.

Proper storage and handling are crucial; excessive humidity, temperature fluctuations, or physical shocks during transportation can impact performance.

The device is RoHS-compliant, ensuring suitability for environmentally regulated markets.

The product is not intended for direct deployment in critical safety, aerospace, or high-reliability life-support applications unless specifically evaluated and approved for such use cases by Murata.
