Midi Spring®

Air Core Inductors

符合RoHS AEC-Q flag
Our Midi Spring® air core inductors have exceptionaly high Q factors and very tight inductance tolerances, making them suitable for narrowband RF amplifier matching and tuning applications.  As their name implies, air core inductors do not use a magnetic core, resulting in high Q and the lowest possible losses for high-frequency applications.  They can withstand high temperatures, meeting AEC-Q200 Grade 1 (−40°C to +125°C) requirements.  High-reliability versions are available for space, military, and other critical applications.

 
  • Inductance values from 22 nH to 150 nH
  • Exceptionally high Q even at low frequencies; Handles up to 3.5 Amps current
  • Tight tolerance (as low as ±2%) can eliminate circuit tuning
  • Flat top jacket for mechanical stability and reliable pick and place operations
  • Solder coated leads ensure reliable soldering
  • AEC-Q200 Grade 1 (−40°C to +125°C)

注释
  1. When ordering, please specify tolerance, termination and packaging codes: e.g. 1812SMS-R12JLC
  2. Inductance tested at 150 MHz on an Agilent/HP 4286A LCR meter or equivalent with a Coilcraft SMD-A test fixture and correlation.
  3. Tolerances in bold are stocked for immediate shipment.
  4. Q tested at 150 MHz on an Agilent/HP 4291A Impedance Analyzer with an Agilent/HP 16193 test fixture or equivalent.
  5. SRF tested on the Agilent/HP 8753D Network Analyzer or equivalent and a Coilcraft CCF1248 test fixture.
  6. DCR tested on the Cambridge Technology Model 510 Micro-ohmmeter or equivalent. For other operating temperatures, use this DCR at Temperature calculator.
  7. Current that causes a 15°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
