Murata Manufacturing Co., Ltd. is claiming the smallest and thinnest 1-µF LW reversed multi-layer ceramic capacitor (MLCC) for automotive applications with the introduction of its LLC series. Featuring a reversed termination for low equivalent series inductance (ESL), the automotive-grade MLCCs tout the industry’s first 0.18-mm profile package.
In addition, the 1-µF capacitance in a 0.5 × 1.0 mm footprint makes the parts the smallest in the market, Murata said.

The small size is achieved using Murata’s proprietary thin-layer forming and high-precision lamination technology, in combination with advanced material atomization and homogenization techniques. The result is about a 20% reduction in component height compared with existing parts, according to the company.
Murata said the smaller size allows the capacitors to fit more easily on the backside of circuit boards. It also allows the parts to be placed in optimum positions for decoupling of processor power rails, close to the die. This reduces the number of capacitors required, thus saving cost and increasing system reliability, the company said.
The MLCC series features low equivalent series resistance (ESR) and a reduction in ESL, which is reported to reduce the high-frequency impedance of the capacitors. “This improves circuit performance to meet the requirements of modern, low-voltage, compute-intensive applications such as automotive advanced driver-assistance systems (ADAS),” Murata said.
The LLC series complies with AEC-Q200 requirements, passing the 1,000 temperature cycle test and temperature/humidity endurance test of 85°C at 80-85% humidity for 1,000 hours. The operating temperature range is -55℃ to 125℃. Click here for additional product information.
