CHIPS CERAMIQUE MULTILAYER CERAMIC CHIP CAPACITORS HC HD HA HB THD

Category: Capacitors, Electronics, Exxelia Group

Overview

The datasheet presents specifications for a range of multilayer ceramic chip capacitors known commercially as HC, HD, HB, HA, and THD. These capacitors are designed for high-frequency microwave applications and offer a variety of standard models, including the former types CEC 73, CEC 24, CEC 4, CEC 22, CEC 33, CEC 34, CEC 31, and CEC 32. The products come in different physical dimensions, with the length (L), width (h), and thickness (e) in millimeters, with some dimensions having a plus tolerance of 0.2mm.

Electrical Characteristics

These capacitors are categorized by different rated voltages, including 100, 200, 300, and 500 volts, with the temperature coefficient of -55°C to +125°C, and an operating temperature range for HC, HD, HB, and HA. The nominal voltage for these capacitors ranges from 50V to 500V. Additionally, the products are designed to withstand 2.5 times the rated voltage and feature a dissipation factor (tan δ) of less than 0.5%. Insulation resistance varies with capacitance value: less than 4.7pF with >10^4 MΩ, and 4.7pF to 47pF with >10^3 MΩ.

Quality Factor and Capacitance

The datasheet indicates the Quality Factor (Q) can be referenced in a table not provided within the first two pages, implying detailed information is available in subsequent sections. Capacitance values are given either with clear numeric values or with coded marking. The document also describes the coding system used to order these components, which includes information about the capacitance value, tolerance, and rated voltage.

Terminations and Options

These capacitors use a ceramic dielectric suitable for high-frequency applications and feature solderable terminations. The standard models provide options for tape and reel packaging for automated assembly processes. For capacitors with a tin-plated option, additional dimensional tolerance is provided as (E) + 0.5mm.

Ordering Information

When ordering, consumers need to specify the commercial type, capacitance (in pF, nR, or uF), tolerance, rated voltage, and whether a tin-plated option is required. The commercial types are given as HC, HD, HB, HA, or THD, with R extensions indicating the tin-plated options (e.g., HC-R, HD-R).
