Fixed Inductors

1. Overview

Fixed inductors are passive electronic components designed to store energy in magnetic fields when electrical current flows through them. Unlike variable inductors, their inductance values remain constant during operation. These components play critical roles in filtering, signal processing, energy storage, and electromagnetic interference (EMI) suppression across modern electronics, including power supplies, communication systems, and automotive electronics.

2. Main Types and Functional Classification

TypeFunctional CharacteristicsApplication Examples
Wirewound InductorsHigh precision, high current handling, low resistancePower supplies, DC-DC converters
Chip InductorsCompact SMD package, stable performance at high frequenciesMobile devices, RF circuits
Ferrite Bead InductorsEffective high-frequency noise suppressionEMI filtering in digital circuits
Thin-Film InductorsUltra-compact, high Q-factor, tight tolerance5G communication modules, IoT devices

3. Structure and Composition

Typical fixed inductors consist of:

  • Magnetic Core: Made from ferrite, powdered iron, or composite materials to concentrate magnetic flux
  • Coil Structure: Copper wire wound around the core (enamelled or silver-plated)
  • Encapsulation: Molded resin or ceramic coating for mechanical protection and insulation
  • Terminations: Solder-coated ends for PCB mounting (for SMD types) or leaded connections

4. Key Technical Specifications

ParameterDescriptionImportance
Inductance (L)Measured in henrys (H), determines energy storage capacityDefines filtering/energy storage performance
Rated Current (Irated)Maximum DC current before saturationPrevents core saturation and failure
DC Resistance (DCR)Resistance of coil windingsAffects efficiency and thermal performance
Self-Resonant Frequency (SRF)Frequency where inductor behaves as capacitorLimits effective operating frequency range
Q FactorQuality factor indicating efficiencyHigher Q = lower energy losses

5. Application Fields

  • Consumer Electronics: Smartphones, laptops, LED drivers
  • Industrial Equipment: Motor drives, power inverters
  • Automotive Systems: ECU modules, EV battery management
  • Telecom Infrastructure: Base station filters, optical transceivers

6. Leading Manufacturers and Products

VishayIHLP2525CZER1R0M1 H, 12A, composite construction
Coilcraft0402DC-103J10 H, 5% tolerance, ultra-low profile

7. Selection Guidelines

Key considerations during selection:

  • Calculate required inductance based on switching frequency and ripple current
  • Verify rated current exceeds maximum operating current by 20-30%
  • Select SRF higher than circuit operating frequency
  • Consider package size vs. thermal dissipation requirements
  • For EMI suppression: Choose ferrite beads with impedance curves matching target frequencies

8. Industry Trends

Current development trends include:

  • Miniaturization: Sub-0.5mm size inductors for wearable devices
  • High-Frequency Operation: Components supporting >10GHz 5G applications
  • Integrated Solutions: Combined inductor-filter modules
  • Material Innovation: Nanocrystalline cores for higher saturation flux
  • Automotive Focus: AEC-Q qualified parts for EV/HEV systems
