Restriction of the substances contained in the article under Reach:
REACH regulation impose restrictions of product applications and substance ban on the basis of Article 67.1.
The inclusion of a Substance of Very High Concern (SVHC) in the Candidate List creates the duty to communicate information on substances in articles to allow safe use of the article, which is applicable to suppliers in Europe (Reach Article 33). It does not impose any restrictions on the use of the products, nor is it a substance ban. Please check "Murata products containing SVHC and Information on safe use" .

AEC-Q200 compliant product

Products that acquired safety standard certification IEC60384-14.
Safety Standard Certification

Products that are based on the electrical appliance and material safety law of Japan.

Product of 10 to 40kV rated voltage

Low dissipation for high frequency
By devising ceramic materials and electrode materials, low dissipation is achieved in frequency bands of VHF, UHF and microwave or beyond.

Low inductance
This capacitor is designed so that the parasitic inductance component (ESL) that the capacitor has on the high frequency side becomes lower.

Product suitable for acoustic noise reduction and low distortion
This product suppresses acoustic noise, which occurs when a ceramic capacitor is used, by devising the materials and configuration.

Product resistant to deflection cracking
This capacitor is designed to prevent failures as much as possible by short mode caused by cracking when there is board deflection.

Product with solder cracking suppression
“This capacitor is configured with metal terminals and leads connected to the chip. The metal terminals and leads relieve the stress from expansion and contraction of the solder, to suppress solder cracking.”

No DC bias characteristics
Polymer capacitor is no capacitance change with DC bias due to aluminum oxidized film for dielectric.

By making full use of the water repellence of the capacitor surfaces, this product minimizes Ion migration from the external electrodes (Terminations) that results from condensation.

Low-inductance product suitable for noise suppression.
This product has extremely low ESL and is suitable for suppression of noise, including high frequencies.
Contributes to noise suppression as an EMI filter

Product for reflow soldering

Product for flow soldering

Limited to Conductive Glue Mounting
Since silver palladium is used for the external electrodes,the capacitor can be mounted by conductive adhesive.

Product for bonding
Since gold is used for the external electrodes, the capacitor can be mounted by die bonding/wire bonding.

Product for welding
Capacitor configured with lead electrodes and can be mounted by welding. Please contact us about the lead wire material.
