Low Voltage 0402 MLCCs now in ESA QPL

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

Boost your project with Exxelia film capacitors with reduced delivery times!

We are pleased to announce that certain products in our RA and KM film capacitor series, as well as our special PMR range (for the medical and railway markets), now benefit from reduced delivery times.   Reduced lead times for film capacitors of the RA (Polypropylene PP) and KM (Polyphenylene sulfide PPS) families: Indeed, delivery times for film capacitors in the RA and KM ranges have been considerably reduced. Previously, these products had an average lead time of 20 weeks, but through efforts to optimize our supply chain, we have managed to reduce this lead time to just 8 weeks on average! One of the key product of this range is the KM 111 S/T. This high performance film capacitor is ideal for a wide range of applications, such as power electronics, filters, inverters. The KM 111 S/T provides the precise capacitance value needed for special aviation electromechanical applications. With its high operating voltage and high energy density, the KM 111 S/T offers outstanding performance. And now, with a lead time reduced to just 8 weeks, you can incorporate it into your designs faster, accelerating your product development.

In some cases, we have been able to reduce the usual delivery times for these specific products by a factor of 10. This means you can now get the PMR range film capacitors you need in record time! Film capacitors in the PMR range are specifically designed to meet the stringent requirements of medical and railway applications. Their reliability, stability, and extended life make them ideal choices for medical equipment, monitoring devices, rail transportation systems, and more. Thanks to our reduced delivery times, you can now benefit from these advantages without waiting long to receive your products.   PMR EFCO PMR 4 PMR 64
