Johanson is proud to announce the new C-Series High Frequency Multilayer Ceramic Capacitors. These ultra-low loss capacitors are made with Copper electrodes, instead of Palladium and Silver, making them less subject to the price volatility of precious metals. Therefore, prices for these low ESR capacitors will be more stable over time. Available in three cases sizes (0402, 0603, 0805), this series features an enhanced ESR of over 1.5GHz, and was developed with two key design criteria - reliability and lot-to-lot RF consistency. Applications include low power RF, smart metering, RF remote control, broadband wireless equipment, cellular base station equipment, RF matching and filter networks and RF microwave test equipment.

Key Features:
  • EIA case sizes from 0402, 0603 and 0805
  • Lead Free Terminations:
    • Electrodes: Cu
    • Core Termination: Cu
    • Barrier Layer: Ni
    • External Termination Layer: 100% Sn Standard
  • Enhanced High-Q / Low Loss NPO – Lower Loss than Standard NPO
  • RoHS Compliant w/ standard 100% Tin termination
  • Stable COG (NPO) temperature coefficient
  • Highly reliable performance
  • Industry standard case sizes
  • Tape & Reel for surface mount assembly → 7” reels
  • Lower Price than Pd/Ag products
  • Enhanced ESR over 1.5 GHz
Applications:
  • Cellular Phone
  • Low Power RF
  • Handheld Computers & Tablets
  • RF Remote Control
  • Smart Metering
  • Cellular Base Station Equipment
  • Broadband Wireless Equipment
  • RF Matching & Filter Networks

Advantages of a Low Loss Capacitor
  • Extended battery life in mobile equipment
  • Increased power output and higher efficiency from RF power amplifiers
  • Reduced amount of heat generated through ultra-low ESR and High-Q
  • The signal to noise ratio and overall noise temperature can be improved
  • Lower in-band insertion loss (S21) when used in filter networks

How to Order

Global Part Numbering Schema:
Johanson is migrating to a new global part numbering schema.  Below is the new capacitor part numbering. Orders with the legacy part numbering will be accepted for the next few years.  Eventually, all capacitor part numbers will need to shift to the new schema.
