Accelerate the domestic substitution of passive components. 

1.Segment the product application scenarios 

0201 X5R 100nF 10V

X5R Media Compatibility - Standard operating conditions range from 55℃ to 85℃. The micro package is specifically designed for high-density PCBs, featuring high-frequency decoupling for chips and RF noise reduction. Widely used in smartphones, TWS headphones, smartwatches, AR/VR, micro IoT sensors, portable medical devices, for MCU power supply bypass, Bluetooth/Wi-Fi RF filtering, 10V voltage rating reserved for lithium battery charging peak redundancy, extremely small package solves the problem of limited wiring space in thin and light terminals, suppressing circuit noise and improving signal stability. 

1206 X5R 10μF 50V 

High capacitance combined with 50V high voltage rating, the X5R high capacitance low-cost feature is suitable for normal temperature high-power power supply scenarios. It is applied in industrial DC-DC modules, LED drivers, fast charging adapters, security power supplies, communication gateways, strongly absorbing power supply ripple, resisting startup voltage surges, simplifying the number of peripheral capacitors, optimizing the overall EMI performance, and is compatible with large-scale mass production of civilian and general industrial power supplies. 

1206 X7R 10μF 25V 

X7R supports wide temperature media - stable operation within the range of -55℃ to 125℃, with a capacity fluctuation of ≤±15%. It is resistant to high temperatures, aging, and temperature shock. It is suitable for industrial PLCs, frequency converters, vehicle-mounted low-voltage electrical control systems, dashcam devices, and outdoor security equipment, meeting the high reliability requirements for high-temperature enclosed, variable temperature changes, and long-term continuous operation. It is compatible with industrial-level and vehicle-mounted environments with strict requirements. 

2.Core Product Advantages

Precise material layering for precise adaptation, balancing cost and performance.

X5R has high capacity density and outstanding cost performance, suitable for large-scale production in consumer electronics; X7R has excellent wide-temperature stability, specializing in high-temperature, vehicle-mounted, and outdoor high-reliability scenarios, with customizable material selection to optimize material costs.

Closed-loop specification combination covers circuit requirements.

0201 is responsible for precise decoupling of the chip near the source, and the two 1206 high-capacity models undertake power-side energy storage and voltage stabilization, covering low-voltage, high-voltage, normal temperature / wide-temperature operating conditions, simplifying customer BOM selection and supply chain management.

Self-developed process with stable electrical performance.

Self-developed ceramic slurry and high-precision thin-layer stacking process, products have low ESR and low dielectric loss, filtering, voltage stabilization, and anti-surge capabilities对标 international leading brands， with excellent batch consistency.

Full-chain self-production， delivery and supply chain advantages.

The automated production line in Chizhou base is for large-scale production， the entire process of materials， production， and testing is independently controllable， short delivery time， outstanding cost performance， relying on IATF16949 and ISO9001 quality control system， supporting long-term stable supply for major customers， helping the terminal supply chain achieve autonomous control and cost reduction and efficiency improvement.
