MLCCs combine high volumetric capacitance and low ESR.
Press Release Summary:
Offering alternative to polarized tantalum and electrolytic capacitors in filter applications, X7R and X5R series multilayer ceramic capacitors (MLCCs) are packaged in 0402 to 1812 case sizes and offer capacitance values from 100 pF to 100 ÂµF. Available value-added capabilities for these products include non-standard plating finishes, such as gold; affixing of various standard and custom lead frames; as well as screening to various reliability MIL PRF levels.
Original Press Release:
NOVACAP's New High-Capacitance MLCCs Combine High Volumetric Capacitance with Low ESR to Dramatically Reduce Component Dimensions
X7R and X5R series offer alternative to polarized tantalum and electrolytic capacitors in filter applications
VALENCIA, Calif.-- November 11, 2008 -- NOVACAP , a Dover Company (TSE: DOV), introduces a new line of high-capacitance multilayer ceramic capacitors (MLCCs) that combine higher volumetric capacitance per given board area with lower equivalent series resistance (ESR) than alternative solutions. The high-capacitance devices in the new X7R and X5R series are packaged in 0402 to 1812 case sizes with a capacitance value range of 100 pF to 100 µF. These devices are ideal for replacing polarized tantalum and electrolytic capacitors to simplify manufacturing. Their low ESR characteristics, typically one to two orders of magnitude lower than alternative devices at frequencies greater than 10 kHZ, allow for comparable filter circuit designs to be achieved at typically one-third to one-fifth of the capacitance values. Additionally, these devices offer improved reliability performance over tantalum and electrolytic capacitors utilizing less power. Typical applications for these capacitors include digital circuits, power supply bypass capacitors, LCD modules, smoothing capacitors and input-output filters in DC-DC converters.
According to Scott Sentz, Novacap's Director of Marketing, "Novacap is able to offer value-added product processing and test screening to meet each customer's unique design requirements. These additional benefits typically are not offered by other suppliers."
Novacap's value-added capabilities for the X7R and X5R series include:
Ability to provide unique, non-standard plating finishes, such as gold.
Ability to assemble and stack capacitors to increase capacitance for a given board pad space without imposing a height restriction.
Ability to use a single pick-and-place step to put the high-capacitance-value devices into an array along with multiple components (i.e., capacitors, resistor, inductors).
Ability to affix various standard and custom lead frames to improve reliability through thermal and mechanical stress reduction.
Ability to screen for optimum reliability. Products are burned in at an elevated voltage and temperature and are 100% electrically inspected to ascertain conformance to strict performance criteria.
Ability to screen capacitor groups to various reliability MIL PRF levels (Group A, Group B, Group C tests) and provide qualification testing for each customer's SCD requirements.
Ability to comply with environmentally friendly standards such as RoHS.
