Boards for GPS antennas in mobile phones are available from 12 to 9mm square. Plates for capacitors in isolators are available in 50mm square with various types of material.

BC Series

BC Series

Larger capacitance values in smaller sizes compared to conventional materials. Low impedance, high frequency characteristic. Suitable for noise reduction for consumer electronics and industrial machines.

FSF Series (for NFC, Wireless Charger, RFID)

FSF Series (for NFC, Wireless Charger, RFID)

FSF Series is a thin flexible sintered ferrite sheet, which suppresses the effect of metals to improve communication of several applications, for example NFC, RFID device and wireless charger due to high magnetic permeability. ■ High Magnetic Permeability Improve properties of devices, for example increase distance of communication for several applications. FSF131 and FSF151 have relatively high μ' (about 130 - 150) and low μ'' at 13.56MHz, which improves performance of NFC and RFID devices. FSF201 and FSF501 have relatively high μ' (about 200 - 500) and low μ'' at 100-200kHz, which improves performance of wireless charger. ■ Thin flexible ferrite sheets Our thin ferrite sheet is laminated with sintered ferrite ceramics, PET film and adhesive tape. A slit formation enables the laminated ferrite sheets to be flexible. Yet, it still retains relatively high μ’ and low μ” at a tuned range of frequency, thus it is suitable for compact mobile devices.

CNA Series

CNA Series

CNA series are an array type capacitors which 4 elements of 3-terminal capacitors set inside of one chip of 3216 size. They are effective on cost reduction of mounting and space-saving for 3-terminal capacitors on signal lines. They are designed to control cross talk. The common gland electrode built in a chip ensures complete grounding of all lines at the gland on both ends.

Voltage Controlled Oscillators

Voltage Controlled Oscillators

MARUWA has developed the Voltage Controlled Oscillators (VCO) by applying the ceramic technologies which we have cultivated for many years. Our advantage is that we have integrated production processes from raw material process by using own dielectric ceramics (coaxial resonators). VCO can be customized, such as extremely small size model, high CN model (using own coaxial resonator), etc.
