What Calramic Technologies does
Calramic Technologies LLC is a Reno, Nevada-based manufacturer of high voltage ceramic capacitors, founded in 2002, producing components rated from 500VDC to 80KVDC for military, commercial, and space-grade applications. Its product portfolio spans radial leaded, surface mount, multilayer chip, single-layer bare disc and rectangular, switch-mode power supply (SMPS), and 200°C rated high-temperature capacitor families, supported by a proprietary Double Action Pressing Technology that produces uniform fired ceramic density and MIL-PRF-49467 compliant screening including partial discharge and up to 4000-hour life testing. Custom designs and catalog modifications account for approximately 40% of production, with rapid prototype turnaround and no minimum quantity requirements, indicating a hybrid catalog/engineered-to-order business model.
The company serves aerospace, defense, space satellite, industrial (geothermal, down-hole, power conversion), and medical (X-ray, mass spectroscopy) end markets, with primary vertical emphasis on aerospace and defense per its segmentation. Go-to-market is B2B sales-led via direct sales representatives in the US and Canada, supplemented by international distributors covering 200+ countries and a DigiKey partnership for online catalog distribution. Pricing is unit-based with standard lead times of 10-14 weeks and a 2-3 week expedited FAST TRACK option; the company is ISO 9001:2015 certified and maintains a no-obsolescence policy for designed-in products.
In June 2026, HEICO Corporation's Exxelia subsidiary acquired a 90% ownership stake, providing a US-based ceramic capacitor platform within HEICO's Electronic Technologies Group; founder and CEO Jeff Day retained 10% and continues to lead the company, which operates with 40+ employees from its Reno facility.
