Category: Capacitors, Electronics, Kemet Electronics Corporation

Summary of KEMET Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs) – Commercial “L” Series

KEMET’s Commercial ‘L’ Series SMD MLCCs feature the high-performance COG (NPO) dielectric and are tailored for applications requiring stable capacitance, such as in military, aerospace, and high-reliability industrial environments. These capacitors are offered with tin/lead (SnPb) termination to address specific applications where non-RoHS compliant solutions are essential. This series ensures robust lead-containing termination systems, ideal for critical and resonant circuit applications.

Operating Temperature and Capacitance Stability: With a temperature coefficient of just ±30 ppm/°C, the capacitors work efficiently between -55°C to +125°C. The COG dielectric provides stability, showing no change in capacitance over time or with voltage application, and an insignificant change with temperature fluctuations.

Capacitor Specifications: KEMET offers a variety of case sizes, from EIA 0402 to 2225, and includes DC voltage ratings from 10 V up to 250 V. Capacitance values range from 0.5 pF to 0.47 µF. Available tolerance options are extensive, ranging from ±0.10 pF to ±20%. These capacitors exhibit low equivalent series resistance (ESR) and equivalent series inductance (ESL), meaning they can handle high ripple currents and have no piezoelectric noise, ensuring high-frequency stability.

Packaging and Ordering Options: Customers can order the products in bulk bag or on a reel, both unmarked, with specific ordering codes for each packaging type. KEMET also provides an option for a 2 mm pitch reel for a doubled packaging quantity. While default packaging does not require an ordering code, the datasheet encourages contact with KEMET for special packaging, marking, or product modifications.

Key Benefits: These capacitors are non-polar, making installation hassle-free. The termination finish is SnPb plated, with a minimum of 5% lead, endorsing reliability. Additionally, flexible termination options are available on request, ensuring the product can be adapted for various surface mount technologies and requirements.

Additional Services: For specific and atypical applications, clients can directly contact KEMET for additional capacitance tolerances, termination finishes, other dielectrics, or higher voltage ratings.
