Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs) XZR Dielectric – KEMET

Category: Capacitors, Electronics, Kemet Electronics Corporation

Overview and Benefits

KEMET’s Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs) feature the XZR dielectric suitable for commercial-grade applications. These capacitors can operate within a temperature range of -55°C to +125°C and are characterized by the Electronics Components, Assemblies and Materials Association (EIA) as a Class II material, indicating their adequacy for bypass and decoupling applications or for non-critical frequency discriminating circuits. The XZR dielectric is highlighted for being temperature stable and showing minimal change in capacitance across a wide range of ambient temperatures, with a predictably limited change of +15% from -55°C to +125°C.

Key Features:

Operating temperature range from -55°C to +125°C.
Compliance with Lead (Pb)-free, RoHS, and REACH standards.
Dielectric strength that maintains stability across temperatures.
Availability in various case sizes: EIA 0402 to 2225.
DC voltage ratings spanning from 6.3 V to 250 V.
Capacitance range from 10 pF to 47 pF, with capacitance tolerances of +5%, +10%, and +20%.
Non-polar design simplifies installation.
100% pure matte tin-plated termination finish offering excellent solderability.
Optional SnPb termination finish upon request.

Applications

The XZR SMD MLCCs are commonly used in decoupling, bypass, filtering, and transient voltage suppression configurations. KEMET’s innovative technology makes these capacitors a suitable choice for a broad range of electronic devices seeking reliable performance.

Ordering Information and Packaging

Clients can specify their requirements through a detailed ordering code system covering case size, capacitance, voltage rating, tolerance, and termination finish. For instance, the ordering code sequence details the case size specification, series code, capacitance in picoFarads (pF), tolerance, rated voltage, and design. These capacitors come in a standard matte tin termination (denoted by “C” for 100% pure matte Sn), with additional termination finish options upon request.

There are several packaging options, including bulk bags and different reel sizes, both marked and unmarked, with the provision of increasing packaging quantity through a 2 mm pitch option available for certain case sizes. Default packaging is provided as “Bulk Bag,” and capacitors without packaging codes are supplied this way. KEMET offers support for clients who need special marking options such as laser marking.

KEMET Electronics Corporation, located in Fort Lauderdale, FL, stands behind these SMD MLCCs, providing comprehensive support and information for potential buyers and existing clients.
