Multilayer Ceramic Capacitors: TDK expands MLCC lineup with new state-of-the-art, low-resistance soft termination types
The latest merchandise contains resin coatings that exclusively cover one side of the circuit board. TDK has incorporated a unique design and structure to produce reliable and low-resistance products. They have introduced a fresh lineup of capacitors that boast a high capacitance of 22 ㎌ in 3216 size and 47 ㎌ in 3225 size. The commodities are available in both automotive grade (complying with AEC-Q200) and commercial grade, showcasing significant enhancements.
TDK Corporation (TSE:6762) has grown its CN range of multilayer ceramic capacitors (MLCCs) with an uncommon design and structure. This design deviates from the typical soft termination MLCCs. Instead, the terminal electrodes are only partially covered with resin layers, allowing electric current to flow outside these layers. This reduces electrical resistance and is a unique innovation in the industry. Moreover, TDK expanded its range to address market needs for large-value capacitances by adding the CNA series (automotive grade) and CNC series (commercial grade) products to the roster.
The latest MLCCs have a capacity of up to 22㎌ in 3216 size, which measures 3.2 × 1.6 × 1.6 ㎜ (length x width x thickness), and up to 47㎌ in 3225 size, which measures 3.2 × 2.5 × 2.5 ㎜. They also come with soft termination that has low-resistance. This means that these MLCCs are able to hold more electrical charge than typical products, which can help reduce the number of parts required and ultimately the size of the device.
MLCCs featuring soft termination are designed to prevent any short circuits that may occur in power and battery lines. Nonetheless, it's worth noting that the presence of soft termination does come with a slightly increased resistance in terminal electrodes. To reduce losses, it's crucial to maintain a low level of resistance.
The CNA series for automobiles meet AEC-Q200 standards.
The commencement of mass production is set to begin on September 2023. These items are an extension of the earlier launched CN series in September 2021, since there is still a growing requirement for more significant capacitance.
, TDK has reported that they will be implementing new measures to improve the efficiency of their manufacturing process. Starting in September 2023, TDK plans to put new strategies in place to make their manufacturing process more productive and effective, according to their recent announcement.
If you want an automotive grade product, go for CNA, but for a commercial grade, CNC is your best bet. You can easily buy samples from the product page that pops up after selecting the Type option.
