■ Features
● Capable of being Re-fl ow or fl ow soldered.
● Unique Ceramic Core/Laser-cut Technology.
● Non polarity product.
● High self resonance frequency.
● Good for mounting.
● RoHS compliant
■ Recommended Applications
● RF circuitry for cellular phones and wireless communication equipment.
■ Explanation of Part Numbers
■ Storage Conditions
● Package : Normal temperature (–5 to 35 °C), normal humidity (85 %RH max.), shall not be exposed to
direct sunlight and harmful gases and care should be taken so as not to cause dew.
● Operating Temperature : –40 to +85 °C
■ Storage Period
● Solderability may be reduced due to the conditions of high temperature and high humidity which causes the oxidation
of tin-plated terminals. Even if storage conditions are within specifi ed limits, solderability may be reduced with the
passage of time. Therefore, please control the storage conditions and try to use the product within 6 months of receipt.
