Low Voltage 0402 MLCCs now in ESA QPL

CEC and CNC series of low voltage ceramic capacitors have received the QPL certification for the 0402 case size. It is the smallest QPL-certified case size completing Exxelia’s MLCCs QPL-listed ranges.


Exxelia ranges of low voltage MLCC for surface mounting, CEC19 and CNC19, have achieved the Qualified Part List (QPL) status under the criteria of the European Space Component Coordination’s (ESCC) 3009/042 and 3009/043 respectively. The case size 0402 QPL-qualified parts are available from 10V to 25V, enabling substantial miniaturization and cost-saving. Dielectrics are based either in the very stable NPO (type 1) or the high capacitance X7R (type 2). CEC and CNC series combine high capacitance values with high thermal and voltage stability. Versions with polymer terminations are also QPL-certified. 

These ranges of versatile chip capacitors are intended for use in a wide variety of aerospace applications requiring the highest level of reliability: satellites, launch vehicles, payloads, etc. 

CEC19 features:
- very stable NPO dielectric 
- maximum capacitance values: 330pF in 10V, 120pF in 16V and 100pF in 25V,
- large operating temperatures: -55°C to 125°C

CNC19 features:
- high capacitance X7R dielectric
- high capacitance rating values: from 68pF to 12nF in 10V, 8.2nF in 16V and 5.6nF in 25V
- large operating temperatures: -55°C to 125°C

New Plug&Play filters for datacenters and mission critical facilities

Electronic equipment can leak sensitive information over conducted or radiated electromagnetic emanations, and signals transmitted down unprotected lines can potentially be intercepted. That’s why filters are implemented into systems to prevent EMI disturbances, as TEMPEST filters stop the high frequency EM signals (or noise) emanating inside the secured environment. Exxelia has a long history of manufacturing state-of-the-art electromagnetic interference (EMI) filtering technologies for space, avionic and defense markets. Thanks to this in-depth knowledge, Exxelia came to the conclusion that the installation of a product is as critical as its reliability, especially when shielding continuity and sensitive copper terminals are involved. That’s where Exxelia’s new full range of TEMPEST pluggable filters will save time and spare headaches! The 9260W series is a multi-socket line extension with a built-in 16A Tempest filter (minimum 60dB, from 100KHz to 1GHz), CE qualified according to EM 60950-1 standard. 9260W series Plug&Play solution is available with UK, US and EU standard plugs and can be provided with any other standard plug upon request. In addition, Exxelia completed its offer with the 9259W series of pluggable filters featuring various plug interfaces such as VGA/DVI, USB, Ethernet, Phone, Audio and much more. 9260W series and 9259W series are both fully compliant with EMC expectations and allow considerable time saving and cost-effectiveness. When a standard filter needs to be wired and shielded to each socket one-by-one before carefully re-closing the whole equipment, Exxelia new series can be installed using no special tools and with a smaller footprint. To all people handling sensitive information, a simple plugging operation is now enough to protect their data. Available now, 9259W and 9260W series are fully customizable upon request.
