Ultrastable ceramic chips target Bluetooth

NIC Eurotech has added a new range of low ESR multilayer ceramic chip capacitors to its portfolio of products.

NIC Eurotech has added a new range of low ESR multilayer ceramic chip capacitors to its portfolio of products.

With ESR as low as 0.30ohm for capacitance values between 22 and 47pF at 500MHz, the NMC-L series is ideally suited to high-speed high-frequency applications such as those found in Bluetooth products.

Manufactured using ultrastable low-loss NPO/COG dielectric, the devices are available with values ranging from 0.5 to 47pF.

Both 50 and 100V DC-rated parts are available.

A broad operating temperature range of -55 to +125C makes them suitable for use in most environments.

Capacitance stability is also very high with a figure of 0 +/- 30ppm/C quoted across the temperature range.

Many wireless and Bluetooth designs are housed in extremely small enclosures.

The NMC-L range is offered in both 0603 and 0805 case sizes making placement easy in such applications where printed circuit boards can be extremely densely populated.

An even smaller 0402 version is currently in development.

Nickel barrier terminations and stringent quality controls in the manufacturing process mean that NMC-L ceramic chip capacitors have excellent mechanical strength.

This is particularly important in portable communications applications where equipment has to meet tough vibration and drop test specifications.

Supplied in tape and reel packaging, the NMC-L range is compatible with both reflow and flow soldering processes.
