CalRamic Single Layer Disc

Exxelia CalRamic has a variety of High Voltage Ceramic Capacitor inventory that are in-stock and can ship same-day upon receipt of your order. If you are looking for prototype quantities, or initial LRIP quantities, contact us for part specific availability.  We can sometimes ship the same day ARO.

Standard ceramic capacitor lead times typically range from 8 to 14 weeks, depending on the product type, configuration, and manufacturing requirements. Leaded and coated  disc capacitors and leaded and coated multilayer capacitors may have different production timelines. Space-level capacitors, enhanced testing, and additional screening requirements may extend lead times slightly. Exxelia-CalRamic is committed to dependable delivery performance and has a strong track record of meeting agreed upon schedules.

Exxelia-CalRamic does not impose standard minimum order quantity requirements. We support a wide range of customer needs, from single-capacitor requirements for engineering  evaluation or prototype development to production quantities in the thousands. Order quantities are evaluated based on the customer’s application, technical requirements and production schedule.

Custom designs and catalog product modifications are 40% of what we manufacture to help our clients in their specific High Voltage requirements.  Sometimes this can be done at no additional cost to the client.

No, Exxelia CalRamic Technologies does not obsolete products that have been designed for a client.  It is our objective to maintain our ceramic capacitor product mix and supply for our clients without discontinuation.

Exxelia-CalRamic offers a range of screening options for high-voltage ceramic capacitors, using MIL-PRF-49467 as a reference basis where applicable. Available screening may include full Group A, Partial Discharge, and additional electrical or environmental testing based on customer requirements. When more extensive qualification is needed, Group B screening can also be supported, including fully rated life testing for up to 4,000 hours. Ultrasonic C-SAM screening is available when required for enhanced inspection. CalRamic can also incorporate many customer-specific screening specifications into the manufacturing and test process. For detailed options, pricing, and lead-time impact, please contact Exxelia-CalRamic’s technical team.

Yes, Exxelia CalRamic has the ability, in most cases, to “FAST TRACK” orders when required, and sometimes lead times can be lowered to as little as 2-3 weeks ARO.  This is offered at an additional cost and one of Exxelia CalRamic’ s team members can assist with setting up your expedited order.

Exxelia CalRamic has an extensive Library database of application notes encompassing all aspects of high voltage ceramic capacitors. In this database you can find detailed information around Soldering Multi-Layer Capacitors AN101, Wave Soldering Multi-Layer Capacitors AN102, Soldering Rework Methods AN108 and Soldering Methods for SMPS style capacitors AN116. All these application notes and many more can be found on our Application Notes page and if more information is needed don’t hesitate to contact one of our technical team members.

All Exxelia CalRamic products continue to be proudly manufactured in the USA at our facility in Reno, Nevada. This ensures full compliance with domestic sourcing requirements for US defense and aerospace applications.
