Johanson Dielectrics Inc.Johanson Dielectrics Inc. specializes in the design and manufacturing of passive electronic components, primarily focusing on capacitors, particularly ceramic capacitors. Their components are notable for their high-frequency performance and miniaturization, making them suitable for various advanced electronic applications.
A significant product category offered by Johanson includes multilayer ceramic capacitors (MLCCs), well-known for their stability and reliability under varying environmental conditions. These MLCCs come in various capacitor types, such as Class 1 (NP0/C0G), which exhibits precise capacitance with low temperature dependency, and Class 2 (X7R, Y5V), which allows for higher capacitance values with some tolerances in temperature and voltage. The capacitors are available in a wide range of capacitance values, voltage ratings, and dielectrics, tailored for diverse circuit requirements.
In addition to conventional MLCCs, Johanson manufactures coaxial capacitors characterized by their compact design for RF applications. These components are used extensively in wireless communications, where performance at high frequencies is critical. The company's capacitors often feature low equivalent series resistance (ESR) and high self-resonant frequencies, optimizing them for signal integrity in high-speed digital and RF circuits.
Johanson Dielectrics also emphasizes manufacturing techniques and materials that enhance component durability and thermal performance. Their products typically operate in a range of –55°C to +125°C, accommodating various operational environments encountered in telecommunications, automotive electronics, and consumer devices. Applications include filtering, decoupling, and tuning circuits in RF devices, meeting stringent standards required in aerospace and medical electronics.
The company serves numerous industries, notably telecommunications, automotive, consumer electronics, and industrial automation, where miniaturized and reliable passive components play a critical role. Johanson Dielectrics’ emphasis on high-frequency performance and versatile application capabilities positions them as a key player in the passive components market.
